Question about Apple iMac G5 Desktop

IMac G5 CASE SCREWS STRIPPED

I went to replace my hard drive in my Pre-iSight G5-- only to discover that the (3) captive screws on the bottom of the computer that hold the case together had been STRIPPED during a previous repair at an Apple Store. Only the left screw even seemed to work (barely). The right screw was frozen and the middle screw just rotated endlessly. (I had never been opened the computer myself.) Now, the computer is out of warranty. I would love to be able to replace and/or fix the screws myself... but don't know if I can based on the fact that all (3) are captive. Is there any recourse here? Thanks!

    These screws are CAPTIVE-- which means they cannot be removed and replaced. I am looking to see if there is a part that would contain new screws, etc.

  • ashman100 Jan 29, 2009

    I am inquring about the (3) CAPTIVE screws on the bottom of an iMac G5. Your solution was for an iMac G4-- which is a completely different machine than an iMac G5. Your solution does not apply to my question.

  • ashman100 Jan 29, 2009

    Where can I find these screws?

  • ashman100 Jan 29, 2009

    The Apple Store thinks the only way I can get the computer back together is to replace the entire case... As the screws are captive. Any more thoughts?

  • ashman100 Jan 29, 2009

    Again, the screws are CAPTIVE and cannot be replaced in the normal method. I am inquiring to how I can replace CAPTIVE screws and if anyone knows if i can find a replace ment part or parts... Without having to replace the entire computer case.

  • ashman100 Jan 29, 2009

    I originally posted here and paid for EXPERT iMac advice. I understand that captive screws cannot be replaced but wonder if there is a part I can purchase that would not entail replacing the entire case.

  • ashman100 Jan 29, 2009

    It is a flat panel iMac G5 20"-- pre iSight model.

  • ashman100 Jan 29, 2009

    I know this, thanks... But my problem remains unsolved.

  • ashman100 Jan 29, 2009

    Thanks. It is actually the front part of the case (not the back) that holds the captive screws at the bottom. Is there any way to replace CAPTIVE screws?

  • ashman100 Jan 29, 2009

    Thanks. If all else fails, I may try that!

  • ashman100 Jan 30, 2009

    Hi. Thanks, as I stated in my original description of the problem-- I did NOT remove any screws. The screws are captive to the base of the computer... so, unfortunately, this idea won't work.

  • ashman100 Jan 30, 2009

    There was nothing in your reply for me to try.

  • ashman100 Jan 30, 2009

    Thanks Robert. Can you tell me how to remove the current stripped captive screws (without harming the interior contents) and how I would measure them to get a slightly larger size? Remember, I have never done this before. This is a computer case and I have to be delicate with the exterior as well as the interior.

  • ashman100 Jan 30, 2009

    Since they are CAPTIVE screws... I still need to know how to get all the screws out of the case without damaging anything the computer's interior. Thanks.

  • ashman100 Jan 30, 2009

    The screws I am looking to replace are the (3) captive screws at the bottom of the computer that are regular Size 2 Phillips head captive screws. The torx screws you noted are not the same thing and the replacement power supply instructions you provided are a link for a 17" iMac-- not a 20" iMac.

  • ashman100 Jan 30, 2009

    I like the idea about the WD-40 but the stripped screws are CAPTIVE... SO I CANNOT REMOVE BY REGULAR MEANS. Thanks!

  • ashman100 Feb 01, 2009

    Not sure I want to go cutting into the interior of the computer... but thanks.

  • ashman100 Feb 01, 2009

    I have already opened the unit. Fully reading my problem description, you would see my problem is NOT opening the unit... But getting the unit to stay closed using the stripped captive screws. Thanks.

  • ashman100 Feb 01, 2009

    It seems here the only solution to this problem is to have an authorized Apple Service Center replace the entire computer case... Therefore giving me new, unstripped captive screws to hold the contents of the computer together.

  • ashman100 Feb 01, 2009

    Yes, I have seen this pdf tutorial before. Too bad the Mac "Geniuses" at the Apple Store didn't follow them-- as they are the ones that stripped the screws to begin with. Of cours, I never thought to look at my computer two years ago after the repair... Who would have thought Apple repair people would be clumsy enough to strip captive screws?

  • ashman100 Feb 01, 2009

    t seems here the only solution to this problem is to have an authorized Apple Service Center replace the entire computer case... Therefore giving me new, unstripped captive screws to hold the contents of the computer together.

  • ashman100 Feb 01, 2009

    I absolutly agree. When I started the question on this forum, I thought-- given Apple's track record-- how hard could it be to replace (3) captive screws? I thought somebody would steer me to where I could buy the metal screen (which holds the screws) or an even easier solution. But I have come to realize that there is no solution other than replace the entire case-- just to get working screws. Unfortunately, Apple effected their repair almost (2) years ago and I never thought to look at the case screws before I decided to replace the hard drive. The computer, of course, is now OUT of warranty. What type of "competent" computer technician would make such a rudimentary mistake as stripping case screws?

Hi and welcome to FixYa,

To your concern:

  • left & middle screw, use a flat screw driver to pry it out (inserted between the head's bottom and casing) while turning with the Philips screwdriver the slot on the head;
  • right screw, if it is not flushed to the casing (countersunk), then you can cut a slot that would accommodate a flat bladed screw driver.
  • the only component in danger of being damaged when the computer is jarred or subjected to a bit of shock would be the hard drive, but since its replacement is the purpose of opening the case, then a little force could be exerted without fear of compounding the issue.
  • others have posted possible source of replacement although perhaps your friendly neighborhood computer geek/shop would a few replacement screws sitting around.
Good luck and thank you for using FixYa.

If you are looking for replacement screws you can buy them below:

922-6800 Apple iMac G5 T-10 Screw


Internal Case Screw Screws : Apple iMac 20" G5
If you want to replace them with regular screws, then you need to extract one to know the length, the diameter, and the pitch.

If you want to free the screw in the middle you may need to remove power supply, in that case see instructions here.

    The replacement instructions are roughly the same for 17" iMac as a 20".

    You can only lose the captive screws, you cannot remove them.

    You cannot replace captive screws with same screws, you need to put in place regular screws.




  • Ginko
    Ginko Feb 01, 2009

    This things can happen.

    Probably an inexperienced technician damaged the case screws and decided to remove them.

    The original captive screws may be replaced with adapted regular screws, but that will be an arranged solution.

    The only proper fix is replacing the case.

    Try also contagting Apple, and complaining and telling them the story, if you escalate the problem to a customer support manager you can have the replacement part, or the repair free from Apple customer support.

Just replace the screws with a slightly larger thread

this will give you an idea of what is available (which you should be able to purchase at any hardware store)

If you can see the part that the screws are locked into, put a drop of super glue ion it. This will reconnect the broken piece to the case and you should be able to turn the screws out. When you reinsert them, turn them backwards until you freel a click, then turn it the right way.

    You could cut them off with a good diagonal cutter or dremel tool and then put new screws in.

You can replace them with 1 size larger captive screws that you can get at most hardware stores,You can also use a standard coarse thread case screw that is slightly larger than the captive hole,just make sure the length is the same.

Take it to the normal /local repair center and get it opened as they have all types of tools to open the unit and as just for getting the screws opened they will normally not charge any thing.

U can spray wd-40 at the sides of the screw and let it remain there for 10 minutes  that will loosen the screw and then you can remove it with a proper screw driver.also u can use thick clipper to hold a grip on the head of the screws and spin them to remove them.

There are 2 things that I can think of to try

The first would be to use JB weld to adhere a scredriver directly to the screw itself, you will lose both the screw and the screw driver but i would guess that you would rather replace those then the computer

The second i would be less incliened to do, but you could drill the screws out with a small drill. Be Very careful to pay attention if any shavings get inside the case, maybe position a magnit close to catch the shavings.

The screw that spins will be the dificult one, however with the JB weld you should be able to pull on it while unscrewing it.

If you do not know what JB weld is, it is a chemical compound that you have to mix in order to repair metal items, in this case it would be great to attach to the screws.

A drill bit will be your best solution.
Using the one screw you did remove, size up a bit just smaller than the screw.
Drill straight down the center and crush it in on itself with a pair of pliers and remove it.

Additionally, you may try a jewelers flat screwdriver to wedge under the screwhead as you loosen it with your other screwdriver.

Ase mechanic:
i know i am not a computer mechanic, but in tight situations like this there are tiny vise grips that may grab the head of the screw and while twisting and pulling upward you may be able to pull the screws out. they are needle nose vise grips.
Just thought I could help, sometimes a tech will do things that aren't unethinical but do work.

  • Ekse Feb 01, 2009

    Well, maybe you should get the person who broke the screws to pay you a new case.. I don't know all I see is to replace the case if they broke it they should pay it.

  • Ekse Feb 01, 2009

    I don't know what apple policy is but when I break something for example I ones fried a power supply, I bought the guy a new one and installed it without any extra cost to him because it was my fault that it was broken.

    I don't know what kind of policy they have or do they take responsibility for their actions but good luck.

Hallo Ashman
Dont worry too much the screw doesn't matter hardly. When you are screwing you can use a knife to ***** the screw that way it wont rotate freely but come out gradually. There are bigger screws available on a Computer repairing shop you can find it

    Before buying new ones you can buy a screw extractor which will help removing those broken screws from this link.

  • Rylee Smith
    Rylee Smith Jan 29, 2009

    How to use a screw extractor---



  • Grip the extractor bit firmly with clamping pliers or use a "T" Handle.
  • Place the extractor bit into the pilot hole.
  • Using a hammer, tap the extractor firmly into the pilot hole.
  • Now while exerting downward pressure on the extractor, turn the extractor counter-clockwise and remove the damaged screw.
  • If the extractor slips and loses its bite in the screw, try again and tap the extractor more firmly to try and get a good bite. Also, push down more firmly as you turn it counter-clockwise.

    My G5 tower is no longer recognising my external iSight camera. The only thing that happened was that I switched the G5 off and on again, it was working fine previously. Can you help? Many thanks


    Best thing you can do is to determine whether its the port or the camera.
    If you go to the Apple in the upper-left corner, and go to "About this Mac", then click "More information", it will start System Profiler. On the left side, under "Hardware", click on "Firewire" and see if your iSight shows up. If you have another FireWire device, plug it in, and see if it shows up there as well. The solution could just be a dead iSight (hopefully!). The worst case scenario is a dead FireWire bus...
    If you have a dead iSight, I'd guess that ebay would be your best resource at this point. If its a dead bus, I'm afraid it won't be terribly cost effective to fix it :-/

    Isight intermittent. G5 Imac 17" The Isight cam I have now dubbed 10sec cam turns off and has to be restarted.


    I understand from your problem statement that the internal iSight camera in your G5 iMac turns itself off around 10 seconds after you turn it on.
    Create a new temporary user in System Preferences / Accounts. Log out and then log in as this user. Enable the camera. Does it still turn off in 10 seconds? If not, something running in your other user account (a startup program or system preference) is interfering with the operation of your camera.
    If you have a spare external drive, install a fresh version of the Mac OS on that drive, then boot from that drive. Does the camera still turn off in 10 seconds? If not, you should run an OS installation with "archive and install" on your internal drive. If it does, you have a hardware problem that requires a Mac tech. If this is indeed a G5 iMac, the repair will likely not be cost-effective.

    Make sure all cables are disconnected. Make sure you are only undoing the three silver screws along the lower edge of the unit. (These are captive screws and should not be removed).There is one screw at each end and one in the middle. Tilt the cover up and lift it away from the computer.
