What it is
The Unifix coach screw with white zinc plating and integrated washer face (code 0192-006-30-01) is the professional solution for strong fixings in wood, ideal for joiners, building carpentry and structural applications. The hexagonal head ensures a firm grip when driving, while the protective finish ensures durability even in damp or exposed environments.
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.
