With Spax chipboard screws, you assemble timber frameworks, furniture, and interior woodwork cleanly, firmly, and without gaps. Thanks to the partial thread design, the screw draws the top piece tightly against the base timber, preventing gaps and reducing the risk of splitting the wood. The countersunk multi-head sinks flush into the surface to deliver a neat, smooth finish. The PZ2 drive recess ensures a dependable bit grip to avoid slipping during driving, while the Wirox coating delivers enhanced corrosion protection for indoor and sheltered outdoor projects. This pack of 500 steel screws measuring 4 x 60 mm gives you everything needed for strong, professional wood fastenings.
