With the Spax chipboard screw 4 x 60 mm, you achieve strong and weather-resistant timber joints for exterior projects. Made from A2 stainless steel, it provides dependable protection against rust and moisture. The t-star plus T20 drive ensures precise bit engagement and optimal torque transmission without slipping. Thanks to the countersunk multi head, the screw mills cleanly and sits flush with the timber surface without pre-countersinking. The integrated 4CUT point eliminates the need for pre-drilling in softwoods, allowing you to build durable outdoor structures quickly, accurately, and with full control.
