Spax Washer Head Timber Screws Wirox

This pack of 150 Spax Washer Head Timber Screws features a 5mm diameter and 107mm length, making it the longest option in the range and ideal for deeper fixing applications in timber construction and interior work. Subject to applicable national building regulations, this size is well suited to fixing facades, roofs, stairs, main battens, counter battens and structural timber elements where greater thread engagement and holding power are required. The large washer head pulls two components together with great force for secure, reliable joints, while the optimised partial thread keeps overall screw length efficient. The T-Star Plus head provides an extra secure fit when used with a compatible Spax T-Star Plus screwdriver bit.
