Specifications

Which one do I need?

A 75mm screw suits a joint whose overall depth is close to that, so measure before ordering.

How to use

1. Mark the positions and check there are no pipes or cables where a 75mm screw will reach.
2. Use a pilot hole where the material is dense; softer stock may not need one for a 75mm fixing.
3. Push a pozi or cross bit fully into the head before driving each 75mm screw.
4. Do not over-tighten: once the head is flush, the 75mm screw has done its job.
