Resilient fastening performance with Wera
- Effective torque peak absorption: The specialized torsion zone absorbs damaging stress peaks, ensuring you prevent premature bit wear and breakage.
- Extra-hard steel construction: Designed for semi-hard materials, it allows you to drive screws securely without damaging the fastener surface.
- Standard hexagonal drive: The 1/4" hexagonal drive ensures you can effortlessly fit the bit into standard bit holders.
Fasten semi-hard materials with confidence using the Wera 851/1 th bit ph 1 x 25 mm. Its specialized torsion zone effectively absorbs severe torque peaks, protecting your bit against premature wear and sudden breakage. Engineered from extra-hard steel, it allows you to drive Phillips cross-recess screws securely without damaging the fastener head. Featuring a compact 25 mm length and a standard 1/4" hexagon drive conforming to din iso 1173-D 6.3, this bit fits smoothly into any standard bit holder for daily assembly and maintenance tasks.
Scope of delivery
- 851/1 TH bits, PH 1 x 25 mm
Product description
High quality bits for Phillips screws. Screws can be applied without any damage to the surface. The Torsion design means that torque peaks can be absorbed. This prevents premature wear and enhances the service life. Extra-hard; 1/4" hexagon, suitable for holders as per DIN ISO 1173-D 6.3.
- 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 1)
Application
- Phillips screws
Drive
- 1/4" hexagon, suitable for DIN ISO 1173-D 6.3 bit holders
Design
- Torsion-style design to reduce premature wear, extra-hard
Features and benefits
- 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.
