Specifications

Which one do I need?

The first number in 6.0 x 100mm (12 x 4 inch) is the diameter and the second is the length. Measure the thickness of both parts plus the depth you want in the base, then compare the total with 100mm.

How to use

1. Mark the screw positions and check the wall or floor for hidden cables and pipes.
2. Pre-drill a pilot hole in dense timber so the thread has room to start.
3. Choose a TX bit that fills the recess fully, as a loose fit can round it out.
4. Drive the screw until the countersunk head is flush, then stop.
