TIMCO 150INDEXSST timber screws are A4 stainless steel fixings designed for timber-to-timber work, offering strong clamping and corrosion resistance for demanding exterior applications. They’re a practical alternative to traditional coach screws where you want a secure, reliable fixing in wood.

With a hex flange head (countersunk) and fixed washer, plus a helix shank to help clear debris, these 6.7 x 150 screws are well suited to structural-style timber assemblies and situations where corrosion resistance is essential.

Key Features
