Woodworking

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

Constructing stairways

  • Attachment of the treads and risers to the string

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 licensing number Z-9.1-449. Z-9.1-511 – approved by building authorities for fastening rooftop insulation systems

Special properties

  1. Wide overlying Washer head
  2. WIROX P3J: The surface with extremely high protection against corrosion
  3. 4CUT (For screw lengths of 160 mm and larger): significantly reduces the screwing in torque
  4. Partial thread: firm tightening of the upper wood layer
  5. 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.

washer-head-spax-t-star-plus-6-mm-partial-thread-wirox Advantages of a washer head compared to a countersunk head:
Better tightening of connections. Easy bolting of steel parts and sheet metal to wood.
Washer head allows higher beam supporting forces.

Further advantage:
Also narrow and thin wood cross-sections can be bolted with 6 mm Ø thread.
