Wiha 71920 Screwdriver Insert Bit 10 Point 6.3 Mm Hex Drive

Product Description

The WIHA 71920 is a 10-point screwdriver insert bit designed for use with 6.3 mm hex drive power tools and bit holders. Built from steel, it measures 25 mm (1 inch) in overall length and fits the standard 1/4-inch hex shank format used across most cordless drivers and screwdriving systems. This pack ships with 10 individual bits, making it a practical choice for tradespeople who cycle through insert bits regularly during production, panel assembly, or service work. The 10-point drive profile provides solid engagement with matching fastener heads and reduces the risk of cam-out during high-torque driving.

This insert bit is suited for electrical, HVAC, and light mechanical assembly applications where 10-point fasteners are specified. Typical use cases include panel work, equipment assembly, and service tasks requiring a compact bit profile. The 25 mm length fits flush in standard bit holders and quick-change magnetic bit holders, keeping the driver profile low in tight spaces. The pack-of-10 quantity supports bench stocking for production environments or field service kits where bit replacement is routine.

Installation Notes

Insert bits are installed and removed by hand into compatible bit holders — no tools required. Verify that the drive tool is powered down or the battery is removed before changing bits on a cordless driver. Inspect each bit for wear or deformation before use, as damaged bits can strip fastener heads or cause injury. Bits should be stored dry to prevent corrosion on the steel body.
