Specifications

Which one do I need?

Check that 100mm is long enough to pass through the top piece and bite into what is behind it.

How to use

1. Mark the positions and check there are no pipes or cables where a 100mm screw will reach.
2. Use a pilot hole where the material is dense; softer stock may not need one for a 100mm fixing.
3. Push a pozi or cross bit fully into the head before driving each 100mm screw.
4. Do not over-tighten: once the head is flush, the 100mm screw has done its job.
