This variant of the Spax Countersinking Torx Wood Screws is sized at 4.5mm diameter x 40mm length, making it a practical mid-range option for general outdoor timber work where a strong, corrosion-resistant fixing is needed without the bulk of a larger screw. Constructed from A2 1.4567 stainless steel, these screws are fully rust-free and designed to perform reliably when exposed directly to the weather. The T-STAR Plus drive delivers a confident bit connection, and the 4CUT point allows direct driving into most wood types without pre-drilling, saving valuable time on site.
