Tough, for universal use. 1/4" hexagonal, suitable for holders as per DIN ISO 1173-F 6.3.

Design

TORX® with bore hole, tough, for universal use

Features and benefits

TORX® tools with a borehole prevent the unauthorised unfastening of safety screws. The screws contain a pin that protrudes into the drive profile so that "normal" TORX® tools cannot be used. This pin fits into the borehole of TORX® BO tools allowing safety screws to be unfastened.
Tough Wera bits prevent the tip from breaking prematurely. Z-bits usually are the bit for universal screwdriving applications.
