Product Category: Bit for Internal Hexagon
Overview
840/4 Z bits from WERA are extra-rigid bits designed for internal hexagon screws. The bit features WERA's Hex-Plus geometry, which provides larger contact surfaces between the bit and the screw head, aiming to reduce damage to the screw head. 840/4 Z bits are part of Wera's Connection Series 4 and have a 1/4" hexagonal drive.
Function and Construction
- Z-design (extra-rigid) for increased stiffness during rotation.
- Hex-Plus geometry that alters the contact surface between the bit and the screw head.
- 1/4" hexagonal drive end according to Wera connecting series 4.
- Fits holders according to DIN ISO 1173-F 6.3.
Typical Applications
Applications specified by the manufacturer include:
- Screwdriving with internal hexagon screws.
- Use in working with hard materials and general screwdriving tasks.
Practical Notes
840/4 Z bits are supplied in a length and tip size specified by WERA; the bits' construction with Hex-Plus and Z-design must be considered when choosing a holder and application area. Using appropriate holders in accordance with DIN ISO 1173-F 6.3 ensures mechanical fit with the 1/4" drive.
