FAQs

Will these fit my screw gun?

These collated strips are designed to be compatible with the autofeed attachments and collated screwdrivers from all leading power tool brands. They come on standard 50-screw strips. If you're unsure, check your attachment takes 3.5mm screws at 32mm.

Coarse, fine or self-drilling – which do I need?

Coarse thread for timber studs and battens; fine thread for light-gauge metal studs and track up to 0.6mm; self-drilling for heavier steel up to 2mm.

Which length should I choose?

Go by what you're fixing through: shorter screws (25–38mm) suit a single layer of standard plasterboard, longer ones (45–55mm) suit thicker or double-layer boards, and the longest sizes are for thick insulated boards. Always check the board manufacturer's fixing guidance.
