Specifications

Which one do I need?

An 8 gauge screw at 40mm long gives a bit more reach than the shorter twin thread sizes while keeping a slim shank. It is a sensible length when the part you are fixing is moderately thick. Measure the total thickness first and make sure the point will stay inside the material.

How to use

1. Mark the positions and check nothing is hidden behind the surface.
2. Pilot drill in hard or brittle material and near edges.
3. Seat a pozi bit firmly in the recess before you start turning.
4. Drive the screw until the countersunk head is flush, then stop.
5. Check each fixing holds firmly before putting weight on it.
