With Spax 6 x 70 mm chipboard screws, you create strong, durable timber joints with complete confidence. The t-star plus T30 recess delivers positive bit engagement and prevents cam-out, giving you full control and efficient torque transfer during every drive. Thanks to the full-thread design, these screws reliably absorb high tensile and compressive loads for exceptionally firm wood-to-wood connections. The countersunk multi head pulls down cleanly and sits flush with the surface without splitting the timber. In addition, the Wirox coating provides superior corrosion protection for interior joinery, furniture assembly, and covered timber structures.
