Description
The SPAX universal screw, WIROX, countersunk head, Ø 3.5–4.5 mm is a SPAX screw designed for all-round screwing work in wood and panels. On the SPAX universal screw, WIROX, countersunk head, Ø 3.5–4.5 mm, the countersunk head that sits flush with the substrate and the T-STAR plus (Torx) recess give firm guidance and screwing without slipping. The cutting point of the SPAX universal screw, WIROX, countersunk head, Ø 3.5–4.5 mm pushes the fibres aside and limits splitting, including near the edges, with no pilot hole in most softwoods. Thanks to its partial thread, the SPAX universal screw, WIROX, countersunk head, Ø 3.5–4.5 mm pulls two pieces firmly together: the plain shank must at least match the thickness of the piece being fixed for optimal clamping. The zinc-plated WIROX surface of the SPAX universal screw, WIROX, countersunk head, Ø 3.5–4.5 mm gives good corrosion protection for indoor and sheltered applications. The SPAX universal screw, WIROX, countersunk head, Ø 3.5–4.5 mm comes in Ø 3.5/4/4.5 mm and in several lengths to cover a wide range of thicknesses to be joined. The SPAX technical documentation for the SPAX universal screw, WIROX, countersunk head, Ø 3.5–4.5 mm includes an Environmental Product Declaration (EPD).
