Unifix Chippy Woodscrews 4.0 x 40mm in a trade tub of 2,000. The go-to size for fixing sheet materials, plasterboard battens, thin trim, and light carcassing where you want a secure hold without splitting the timber. At 4.0mm gauge and 40mm length, they drive fast into softwood framing without needing a pilot hole in most cases.

Pozi drive with double countersunk head sits flush and pulls the workpiece tight. Single coarse thread at 40° gives fast driving and a strong grip. ZYP (zinc and yellow passivated) finish provides corrosion protection for interior use. CE approved to European construction product standards.
