With the Spax 6 x 240 mm chipboard screw, you create rock-solid timber connections in heavy structural installations. The 65 mm partial thread draws timber beams and thick components tightly together to eliminate unwanted gaps. Featuring the t-star plus T30 recess, it ensures a tight bit fit without cam-out, giving you maximum driving control and power transfer. The countersunk multi-head mills cleanly into the wood to finish flush without splitting, while the 4CUT point eliminates the need for pre-drilling in most softwoods. Protected by the durable Wirox coating, this steel fastener delivers high corrosion resistance throughout demanding interior structures and covered outdoor projects.
