Spax Wirox Washer Head Torx Wood Construction Screws

Great fixing for woodworking attachment of counter-battens and wood based panels (e.g. suction-proof fastening of roof battens).

Application
• The non-threaded part must completely reach through the upper component. The washer head then pulls the upper component tighter to the lower component with each thread rotation.
• Advantages of a washer head compared to a countersunk head: Better tightening of connections also of warped board. Washer head guarantees double the amount of power delivery.

Special Properties
• Wide overlying washer head Washer head
• WIROX P3J: The surface with extremely high protection against corrosion
• SPAX 4CUT cutter (For screw lengths of 160 mm and larger): significantly reduces the screwing in torque
• Partial thread: firm tightening of the upper wood layer
• SPAX T-STAR plus: secure bit grip, no cam-out effect, optimal force transmission

Features and Benefits
• Considerably reduced screwing-in torque and reduced splitting effect
• Length specification and manufacturer logo on the head
• Higher head traction forces than countersunk head screws
• SPAX 4CUT point allows screwing in without pre-drilling (wood-dependent), reduces splitting as square end displaces the fibres
• SPAX ground serrations: up to the point – quick and secure fastening
