Product Description

The WIHA 71706 is a screwdriver insert bit designed for use with 1/4-inch hex quick-change bit holders and power or manual drivers. It features a 6.3 mm (1/4-inch) hex drive shank and measures 25 mm (1 inch) in overall length, making it suited for tight-clearance fastening tasks. The bit drives 3/16-inch hex cap screws and is sized for standard insert-bit compatible tools. Sold in a package of 10, the 71706 is a practical stock-up option for service technicians and tradespeople who regularly work with hex cap fasteners.

This insert bit is appropriate for use in mechanical, electrical, HVAC, and plumbing service applications where hex cap screws are encountered. The compact 25 mm length fits standard 1/4-inch bit holders used with cordless drills, impact drivers, and manual bit holders. It is well suited to panel work, equipment assembly, and service calls requiring consistent hex drive access in confined spaces.

Installation Notes

Insert bits are installed by pressing the bit into a 1/4-inch hex quick-change holder until it seats securely. Verify the holder's retention mechanism is engaged before applying torque. When using with an impact driver, confirm the bit holder is rated for impact use to avoid premature bit failure. Replace worn or damaged bits rather than continuing to use them, as a damaged bit can strip fastener heads.
