Phillips PH1 screwdriver bit
Product 05059805001 is a Phillips PH1 screwdriver bit with a total length of 50 mm, designed for use with Phillips screws. The bit features a built-in torsion zone (TZ) designed to absorb peak torque, thereby reducing stress on the tip during momentary high torque impacts. The bit comes as a 1/4" hexagon drive, compatible with Wera connecting series 4 and holders according to DIN ISO 1173-F 6.3.
Description and Function
- Type: PH 1, suitable for Phillips head screws.
- Torsion zone: absorbs peak loads to extend the bit's lifespan.
- Drive: 1/4" hexagon, suitable for standard holders mentioned in manufacturer documentation.
- Material application: specified as "tough for hard materials" in the manufacturer's specification.
05059805001 is described in the manufacturer's material as a TZ-bit (Torsion Zone) where kinetic energy is diverted away from peak loads. The practical effect is a reduced risk of premature tip breakage and increased lifespan in applications involving repeated or varying torque impacts.
Typical applications
- Use with Phillips screws, as stated in the manufacturer's datasheet.
- Universal screwdriving, where TZ-bits are recommended to handle peak torque.
