Screwdriver Bit 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

• General-purpose slotted screwdriving
• Use with 1/4" bit holders and quick-change chucks

How to use

Insert the 1/4" hex shank into a compatible bit holder or quick-change chuck until it locks.

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.
