Spax A4 Stainless Steel Torx Decking Screws

This variant of the Spax A4 Stainless Steel Torx Decking Screws is supplied in a 6mm diameter, 100mm length, in a pack of 100. At 100mm, these are the longest screws in the range, making them the go-to choice for thick or heavy-duty decking boards, or where an exceptionally deep and secure fixing into the subframe is essential for structural confidence.

Fabricated from high-grade A4 stainless steel, they offer outstanding resistance to corrosion — a critical advantage in exposed outdoor settings where moisture and weathering are constant concerns. The Torx drive head maximises torque transfer and eliminates cam-out, while the cutting ribs on the shank allow clean, split-free penetration even through dense hardwood and close to board edges.

Features and Benefits:
• A4 stainless steel provides maximum corrosion resistance for outdoor use

• Cutting ribs allow clean penetration without splitting, even in hardwood
• Fixing thread provides a strong, secure hold on the deck board
