With the Spax chipboard screw measuring 6 x 180 mm, you achieve strong and precise timber connections every time. The partial thread design with a 65 mm thread length pulls your wooden workpieces firmly and seamlessly against the substructure. Thanks to the t-star plus T30 drive, your bit sits securely in place, maximizing power transfer and preventing slipping during insertion. The countersunk multi head with ribs sinks cleanly and flush into the wood surface without splitting the material. In addition, the durable Wirox coating on steel provides enhanced corrosion protection, ensuring dependable performance for all your timber framing and structural woodwork.
