I need a under cabinet mount

If yours is the one with the rounded top it does not have an under cabinet mounting bracket. The top of the oven is not insulated so it would heat the cabinet above and cause a fire

Kurt,

There is usually a mounting bracket that mounts to the wall and the microwave hooks into that and is held up by the two screws you referred to in your question. Unfortunately, you have not provided enough of the model number for us to look up any info to help you find a new bracket to mount to the wall. Hope this helps!

Um, "machine screws"? Unless you have a metal fitting inside the cabinet for those to screw to, you don't need machine screws.

Assuming you do have the metal fitting, then take that fitting to the hardware store to get the correct screws (and perhaps nuts). How long? Measure the thickness of the bottom of your cabinet, add the thickness of the bracket(s), and get the next size longer.

look at the middle of the tv the 4 screw mount thats wre the tv wall mount gos. good luck

I would say finish the wall, because the microwave needs the space for cooling.

Some are avalible with a mounting bracket for on the wall

You don't use screws for drywall to hang a TV, EVER.  That's a 50 pound TV.  You should only use the heavy stud bolts that came with mounting bracket and bolt them directly into the studs.  If by some chance the mounting didn't come with them, go to Home Depot or Lowes with the mounting tell them what you're doing and they'll get you what you need.  You are using a mounting bracket, aren't you? If by some chance you're trying to do this without a mounting bracket, STOP what you're doing and get a mounting bracket appropriate for your size television.  Go to Monoprice, they're the cheapest and their quality is excellent.  Meritline is good as well, they just take a little longer to get.  See the video below.

mcdevito75 here, Best Bet bring the mounting bracket and bolts recieved with the unit to your local hardware store. they will give you the correct bolts need to mount undera cabinet.

You put a mounting plate on the wall behind where the unit will be mounted. Then the microwave hooks onto the bottom of the mounting plate and you swing it up to the cabinet above it. Then you must screw 2 mounting screws through the floor of the cabinet above into the bracket on top of the microwave.

I don’t know your counter situation, usually you have to put dishwasher in a bottom cabinet and mount both side. Suppose you only have one side to mount, you have to go to home depot to buy a 90 degree metal mounting bar, mount the top part to your top granite support board, the bottom side mount to the dishwasher, it should be a ¾” plywood board underneath the granite, you can use ½” screw to mount it.

Hope this can help you,
