# WERA 867/1 TZ Bits for Torx Socket Screws

TZ-Bits are Z bits with a Torsion zone (T). Torsion bits absorb the damaging peak torque loads in the torsion zone. This prevents premature wear and enhances the service life of the bits.

Z-Bits are ductile, tough bits, for hard materials where bit breakage is an issue such as sheet steel or metal.
