Screw fixing a number sign

Screw fixing a number sign.

This is the most common method of fixing a house sign or house number and it is probably the simplest, but there are one or two things you will need to take into account.
Choice of screw is vital, use either solid brass or preferably stainless steel.
Ordinary steel screws will rust very quickly, brass coated screws will eventually corrode and even galvanised screws will rust if the galvanised coating is scratched, as it surely will be!
The risk from rusting or corroding screws is not just the sign crashing to the ground, but that many house sign materials are susceptible to staining. Slate and stone will stain from rust, and marble will positively love to absorb rust or corrosion stains. Even Granite may stain somewhat, though not quite as badly as other materials, but why take the risk?

Drilling brickwork or masonry.

It is notoriously difficult to Accurately drill masonry walls. With a timber made sign this is not a problem, if the screw holes are a little out of alignment you can simply wind the screw into the timber. Stone signs are not so forgiving, you run the risk of snapping the actual sign! The video below shows how to accurately drill the holes.

I hope the above video helps you avoid the pitfalls that can happen on this apparently simple task.

Plastic Caps.

Many number sign makers supply their signs with plastic cover caps for the screws. I deeply dislike this idea! Firstly the caps encourage damp around the screw head increasing the risk of rust and corrosion, secondly these things simply look cheap and clunky!. This is a very personal opinion of course but if your house sign maker does supply you with these horrible things I urge you to replace them with Stainless steel dome head screws or Stainless steel Pan-head screws.
