Specifications

Which one do I need?

A 6 gauge screw is fairly slim, which helps reduce splitting in thinner pieces. At 30mm long, it suits fixing a thin part onto something a little thicker. If the material is heavy or the joint takes load, a thicker gauge may be a better choice. Hold a screw beside the work to check the length before you start.

How to use

1. Mark each hole and check the screw will not pass right through.
2. Drill a small pilot hole in hardwood or near edges.
3. Use a pozi bit that fits snugly so it does not slip.
4. Drive until the countersunk head is flush and stop there.
5. Test the joint before relying on it.
