TH-Bits are hard 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.
851/4 TH bits
- For Phillips screws
- Torsion zone for absorption of peak loads
- Enhanced service life of the bits
- Particularly hard for semi-hard materials
- 1/4" hexagon drive (Wera connecting series 4)
