With Spax chipboard screws, you create strong, gap-free timber connections with complete confidence. Thanks to the 68 mm partial thread, you can pull beams, joists, and thick boards tightly against the substructure. The countersunk multi-head sinks smoothly into the timber for a clean, flush surface finish. The t-star plus T30 drive recess provides a secure bit fit and maximum torque transfer, preventing cam-out and giving you optimal control during every drive. In addition, the durable wirox coating protects these 6 x 110 mm steel screws against corrosion in interior fittings and sheltered outdoor structures. You get fast, reliable fastening and a solid build every time.
