With Spax chipboard screws, you create strong, flush timber joints for interior construction, framing, and covered outdoor structures. The 61 mm partial thread pulls wooden beams, battens, and boards firmly against the base structure without leaving gaps. Thanks to the 4CUT point and countersunk multi-head, the screw drives in smoothly and sits flush in softwood without pre-drilling or splitting the wood. The t-star plus T20 drive ensures solid bit engagement, transferring maximum torque without slipping. In addition, the Wirox coating provides high corrosion resistance for lasting durability. This 200-piece pack of 5 x 90 mm screws provides dependable performance for your daily woodwork.
