Ruuvauskärki Wera 800/4 Z

The Wera 800/4 Z screwdriver bit is a solid, general-purpose slotted bit with a 1/4" hex shank and an overall length of 89 mm. It is manufactured by Wera for universal use and fits holders conforming to DIN ISO 1173-F 6.3. The bit is intended for accurate turning of slotted screws and for use in hand or bit-holder-mounted applications.

Advantages

The bit offers durable construction for extended service life and consistent tip geometry for reliable engagement with slotted screw heads. Its 1/4" hexagonal shank ensures compatibility with standard bit holders and quick-change adapters, while the 89 mm length provides reach in recessed or confined fastening locations.

Suitable for

How to use

Recommendations

Use the bit with holders conforming to DIN ISO 1173-F 6.3 and select the correct slotted tip size for the screw to minimise cam-out. Inspect the tip for wear before use and replace the bit when tip geometry is visibly degraded.
