These 'devil' screws have additional pieces of metal or plastic that act as anchors and designed to expand behind whatever it is screwed to (drywall, wood etc), to spread out the weight n the hanger or the screw reventing the scrw from slipping out through the hole (and in my case with little chance in hell of ever trying to remove them).

No so easy to you'll need plastic sheeting, brushes, rollers and primer for the paint.

So now I just bought #3 and am scheduled to close on Fri.

Honestly, I would use the cheap plastic ones and expect to replace them.

Fry when the skillet is hot!

Brass body plumbing fixtures no plastic or abs.

If it is way out of the norm like a....recycled beer can wall bonded with a recycled plastic polymer (just the craziest thing I could think of right now) then you stand to have quite an expensive hurdle getting it tested and designed to pass scrutiny. 

I am very curious as to know how they react to heat, like if somebody put a hot tea pot or frying pan down on the counter. 

When you get estimates from folks make sure they say there gonna hang plastic at least.

One thing I've done to keep the walls looking nicer is to put the plastic strips on all the outside corners.
