This variant of the Spax Countersinking Torx Wood Screws is sized at 4mm diameter x 30mm length, making it an ideal choice for lighter outdoor timber fixings where a compact but strong, corrosion-resistant screw is required, such as fixing thinner boards, battens, or trim in exposed locations.

The T-STAR Plus Torx drive provides a secure bit fit, and the 4CUT point means most timber can be fixed without the need for pilot holes, keeping the job moving efficiently.
