Wiha 71934 Hex Screwdriver Insert Bit 1/4 in Drive

Product Description

The WIHA 71934 is a hex screwdriver insert bit designed for driving No. 6 cap screws in production, assembly, and maintenance applications. The bit accepts a standard 1/4 inch hex drive and measures 1 inch in overall length, making it compatible with common bit holders, power screwdrivers, and impact-rated tool handles. Electricians, HVAC technicians, and general trade professionals use insert bits like this for repetitive fastening tasks where a dedicated driver is impractical. The compact 1 inch length suits confined spaces and standard bit-holder depth. Package quantity is 10 bits per pack.

This insert bit is suited for light to medium fastening work on No. 6 cap screws in residential and commercial settings. Typical applications include panel assembly, equipment mounting, and fixture installation where a 1/4 inch drive hex bit is the required interface. The 10-piece pack supports jobsite use where bit wear or loss is a routine consideration, reducing downtime during continuous fastening operations.

Compatibility

Installation Notes

Insert bits are installed and removed by hand into a compatible 1/4 inch hex bit holder or quick-change chuck. Confirm the tool is unpowered and the chuck is fully released before swapping bits. Use the correct cap screw size to avoid bit slippage and fastener damage. Bits showing visible wear or rounding should be replaced before use to prevent cam-out.
