Specifications

Which one do I need?

Measure the combined thickness of what you are joining, then see whether 30mm fits it.

How to use

1. Mark the positions and check there are no pipes or cables where a 30mm screw will reach.
2. Use a pilot hole where the material is dense; softer stock may not need one for a 30mm fixing.
3. Push a pozi or cross bit fully into the head before driving each 30mm screw.
4. Do not over-tighten: once the head is flush, the 30mm screw has done its job.
