Product Description

Product Description

ASSY screws are best driven using the AW Bit which is a mix of the Torx bit and the Phillips bit. Three different bit sizes are available in lengths of up to 50mm (2″).


The AW Bit series is engineered for:

  • Optimum torque transfer
  • Snug fit
  • Self-centering
  • Reduced wobbling

Our bits are hardened to assure long life span, the hardened bits typically perform weakly when used with impact drills. We suggest using low rpm high torque drills (corded).
