Specifications

Which one do I need?

Drywall screws are chosen by length. A 75mm screw is a long option, so it suits fixing through thicker build-ups where a shorter screw would not reach the support behind. For a single thin board onto a stud, a shorter screw is normally enough.

How to use

1. Locate the studs or battens behind the board and mark their lines.
2. Fit a Phillips bit, ideally in a depth-setting holder.
3. Hold the board firmly against the support and drive the screw square.
4. Stop when the bugle head sits just below the surface without tearing the paper facing.
5. Fill over the heads with a suitable filler, then sand smooth before decorating.

FAQs

How deep should 75mm plasterboard screws be driven?

What drive do they use?

A Phillips drive, so use a Phillips bit rather than a pozi bit for the best fit.

How many are in a pack?
