mirror screws

[dmccormick]

We have a plain mirror that we want to hang using mirror screws. It has holes drilled in the corners and we've bought some mirror screws from B&Q, but I'm not sure if that's all I need.

I thought there should be some sort of rubber grommet or cushioning around the screw so that it doesn't press directly onto the glass in case it cracks it, but the screws are just plain metal.

Can I use them directly or do I need some kind of grommet. If the latter, where do I get some and what are they really called ?

There should be a plastic washers that come with it. Are the cap clipped on or dome head bolt type that screw into the screw head.

 

[dmccormick]

the caps are dome headed and screw into the end of the screw.

Them type don't have any washers with them which I don't agree. I normally use 'O' ring seal they use for plumbing such as repairing taps. Be careful not to overtighten the screws.

Ones I usually use have a stepped plastic washer one part fits the hole in the mirror, wider part is countersunk to take the mirror screw.

put rubber o rings under the screws and i would advise under the mirror
as already suggested and dont overtighten the screws as already suggested
o rings usually free from plumbers merchants ours anyway 50 p tops

thanks everyone.
I should complain to B&Q - what's the point of selling mirror screws that are not "fit for purpose"; don't imagine I'll get very far though !

I have used the mirror screws you had bought many times without problem. I usually fix a piece of foam double side tape behind the mirror near each screw. This will take up any irregularitis in the wall & act as a cushion for any movement. It is not necessary to use plastic sleeves/bushes.

I'm with DIYisfun. Any sort of washer front side looks awful and foam behind would be much better. I prefer the flat chrome tops to the domed ones; they hide the reflection of the hole in the glass better.
