Wiha 71946 Hex Insert Bit 1/4 in Drive M10 Impact Rated 10pk

Product Description

The WIHA 71946 is a hex screwdriver insert bit designed for use with 1/4 inch hex drive power tools and bit holders. Manufactured from steel and rated for impact use, this bit delivers the torsional strength needed for high-torque fastening applications. It measures 1 inch in overall length, making it a standard insert format compatible with most quick-change bit holders and impact drivers. Sized for M10 cap screws, it suits common fastener sizes found across mechanical, electrical, and general trade work. The package contains 10 bits, supporting job-site replenishment and reducing downtime when bits wear.

The WIHA 71946 is suited for residential and commercial trade applications where M10 hex fasteners are regularly driven. It is well-suited for use in electrical panel assembly, mechanical equipment installation, and structural fastening tasks where impact-rated tooling is required. The 1 inch OAL fits standard bit holders and magnetic extension bars used by electricians, HVAC technicians, and general contractors. Metric sizing makes it appropriate for equipment and assemblies manufactured to metric fastener standards.

Installation Notes

Insert bits should be seated fully into the bit holder before applying torque. Confirm the quick-change chuck or magnetic holder is secure before driving. Impact-rated bits are intended for use with impact drivers; use in non-impact tools is acceptable but will not cause damage. Inspect bits regularly for wear, rounding, or cracking and replace as needed to prevent fastener damage.
