Special properties

  1. Wide overlying washer head Washer head
  2. WIROX P3J: The surface with extremely high protection against corrosion
  3. SPAX 4CUT cutter (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. SPAX T-STAR plus: secure bit grip, no cam-out effect, optimal force transmission

Features

  1. SPAX 4CUT point: allows screwing in without pre-drilling (wood-dependent), reduces splitting as square end displaces the fibres
  2. SPAX 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.
