Specifications

Which one do I need?

Diameter is the first number in 3.5 x 25mm (6 x 1 inch), and the length is the second; choose the diameter to suit the work and the length to suit the combined thickness.

How to use

1. Clamp or hold the pieces in place so they cannot slip while you mark where each screw goes.
2. Pre-drill where the timber is hard or close to an edge so it does not split.
3. Pick the right size of cross/pozi bit; a worn bit can damage the head.
4. Back off the drill clutch setting so the head finishes level.
