Product description 6 50 mm-long Wera bits tidily arranged in a minimum of space in a practical Bit-Check. The tough viscous bits are suitable for universal use. In the case of the Torsion bits (TZ), torque peaks are additionally absorbed in the Torsion zone. This prevents premature wear and enhances the service life. Upright positionable, multi-component Bit-Check The Torsion design absorbs torque peaks Tough viscous bits for universal use Prevents premature breakage of the drive tip Bit-Check plastic material ensures robustness and durability 6 bits, Torsion-style (T) design to reduce premature wear, tough (Z), for universal use. Features and benefits The Bit-Checks can be positioned upright at the workplace so the tool is always quickly to hand. TZ-Bits are tough bits with a torsion zone. Torsion bits absorb the damaging peak torque loads in the torsion zone. This prevents premature wear and enhances the service life of the bits. Tough Wera bits prevent the tip from breaking prematurely. Z-bits usually are the bit for universal screwdriving applications.
