867/1 TZ TORX® bit TX20 x 25 mm — Product Overview
The 867/1 TZ TORX® bit TX20 x 25 mm is a replaceable TORX® bit from WERA designed for use with a 1/4" hexagon drive. The bit is specified for countersunk TORX® screws and features an integrated torsion zone that reduces the impact of peak torque and minimizes premature wear on the drive tip.
Function and Construction
- Torsion Zone: The bit includes a torsion zone where kinetic energy is dissipated during momentary peak loads, which, according to the manufacturer, increases its lifespan.
- Drive Interface: 1/4" hexagon drive (Wera connecting series 1) for standard holder solutions.
- Dimension: Specified as TX20 with a 25 mm blade length.
- Material Properties: Described by the manufacturer as "tough" for use on hard materials and suitable for universal screwdriving.
Typical Applications
The product documentation explicitly states that the bit is intended for countersunk TORX® screws and for general (universal) screwdriving tasks, where the torsion zone reduces the risk of premature wear or breakage of the tip.
