What it is
The Unifix VG Stardrive yellow-zinc-plated countersunk flat head screw (code 0155-8-160-01) is a structural screw designed for high-strength joints in glulam and prefabricated elements. An ideal solution for heavy carpentry, industrial joinery and timber construction where secure, durable fastenings are needed without pre-drilling.
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 in carpentry work, for fixing into timber, from assembly work to carpentry and for structural fixings, where the fixing is load-bearing and must be calculated.
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.
