What it is
The Unifix TPS chipboard screw (code 0186-24-12-01) is the professional solution for secure, long-lasting fixings in wood and chipboard materials. Designed for carpenters, joiners and installers who require precision and strength in every application.
Wood screws are screws with a wood thread, also supplied with a plug or collar, for assembling timber and fixing frames and battens to walls.
What it is for
Used for woodworking in the joinery shop and for fixing into timber, from assembly work to carpentry.
How to use it
Choose a length that penetrates at least two-thirds into the second piece. In hardwoods or near edges, pre-drill to prevent the wood from splitting. Drive with a bit of the right size, keeping the screwdriver in line and setting the clutch so as not to strip the head.
