Masonry screws are a excellent way to fasten any material to masonry. These can be used in stone, brick or concrete and are a fast reliable way of fastening with no expansion force like you would get with wall plugs or shield anchors.
Firstly ensure that you have the correct size drill for the masonry screw that you are using. Drill a hole and ensure that the hole is deep enough for the masonry screw or it could easily crack the material which it is screwed into.
A cordless drill/driver is best to drive the screw into the hole as lots of effort is required to screw them home. Hold the item to be fastened up to the hole and place the screw in the hole and screw it home.
When the screw is tightened it provides a very good way of fastening to masonry with no expansion force, this means it can be used for close to the edge fixing!
