Specifications

Which one do I need?

Add up the thickness of what you are fixing and the depth you want in the backing material; if the total is close to 45mm, this size is a sensible choice.

How to use

1. Mark each fixing point and check behind the surface for pipes and cables.
2. Drill a pilot hole in hardwood, or close to the end of a board, to lower the risk of splitting.
3. Fit a pozi or cross bit that matches the recess so it does not slip and mark the head.
4. Stop when the countersunk head sits flush with the surface, without over-tightening.
