Features and benefits

The Bit-Checks can be positioned upright at the workplace so the tool is always quickly to hand.
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.
For a firm, wobble-free connection between holder and bit with quick-release action. Simply push sleeve forward to change bits. The non-magnetic version prevents any unwanted attraction of metal filings.
