Wiha 71303 Hex Insert Bit 1/4 in Drive Impact Rated

Product Description

The WIHA 71303 is a metric hex screwdriver insert bit designed for use in 1/4 inch drive bit holders and impact-rated power tools. Built from steel and rated for impact use, this bit delivers reliable torque transfer when driving standard hex fasteners. At 1 inch overall length, it fits standard quick-change holders and compact drill drivers. The ball-end-free design ensures positive seating on flat hex socket fasteners. Licensed electricians, HVAC technicians, and other trade professionals rely on insert bits like this for panel work, equipment assembly, and field service tasks where speed and bit durability matter.

The 71303 is suited for metric hex fastener applications including M1.6 and M2 cap screws commonly found in control panels, motor assemblies, and precision equipment enclosures. Its 1/4 inch drive shank fits universally into standard bit holders, magnetic bit tips, and impact driver chucks. The compact 1 inch overall length makes it practical for use in tight quarters where longer bits would interfere with surrounding components or fastener access.

Installation Notes

Insert bits should be seated fully into the bit holder before applying torque to prevent slipping or premature wear. When used in impact drivers, verify the bit is rated for impact use before installation — this bit carries that rating. Inspect the bit tip for wear or rounding after extended use, as a damaged tip can strip small metric fasteners. No special tools or trade license is required to use insert bits, but trade professionals should follow applicable equipment lockout procedures before accessing fastener points on energized or pressurized systems.
