Woodworking

  • Attachment of counter-battens and wood based panels (e.g. suction-proof fastening of roof battens)

Advantages

  • 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

Approved by building authorities

  • Under Z-9.1-449 as wood connector

Special properties

  1. Wide overlying Washer head
  2. WIROX P3J: The surface with extremely high protection against corrosion
  3. Full thread: absorption of high tensile and compressive forces
  4. T-STAR plus: secure bit grip, no cam-out effect, optimal force transmission

Features

  1. 4CUT: allows screwing in without pre-drilling (wood-dependent), reduces splitting as square end displaces the fibres
  2. ground serrations: up to the point – quick and secure fastening

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.

Better tightening of connections also of warped board. Washer head guarantees double the amount of power delivery.
