I bought new stainless steel countersunk washers and screws for the install.

Still need to pick up stainless screws and or adhesive before installing.

I used Liquid nail on the back side of the unit along with 4 hollow wall anchors and stainless steel screws.

The backsplash matches our range hood, the attached 4 screws are sufficient to secure it on the wall

Easy to install, 4 screw holes

Pre drill your holes for easier screw installation.

For the screws, I used #8 1-inch stainless steel metal screws (I wanted two potential ways to remove the screws out in future, ratchet or screwdriver)

but it was clear of the top screw due to the wall's slope

Top screws hide behind the microwave and the bottom screws hide behind the stove.

I left the protective coating on the panel, peeling back just enough at the corners to allow me to insert the stainless steel screws (which I had to buy separately).

I prefer stainless screws with finishing washers.

Would I buy a 3rd time if needed, absolutely; but while I love the 4 pre drilled hoes, for a couple of pennies more, they should add the screws and anchors like the cabinet hardware companies do

#8 screws are recommended but I used #6 stainless screws and washers to give me a little more leeway
