The WIHA 71956 is a hex screwdriver insert bit designed for use with 1/4 inch drive power tools, impact drivers, and bit holders. The bit measures 1 inch in overall length and fits standard 1/4 inch hex shanks. This package includes 10 bits, making it a practical choice for production environments, service vans, and job sites where bit wear and loss are common. It is suited for licensed electricians, HVAC technicians, plumbers, and other trade professionals who rely on consistent, interchangeable drive bits throughout a workday.
The WIHA 71956 is intended for use with 1/4 inch cap screws in light to medium fastening applications. The compact 1 inch overall length makes it compatible with inline screwdrivers, drill drivers, and right-angle adapters where clearance is limited. The 10-piece pack format supports tool kit restocking and reduces downtime on multi-tech service calls. This bit is appropriate for residential and light commercial trade applications.
Designed as a replacement-style hex insert bit for use with standard 1/4 inch drive bit holders, quick-change chucks, and inline screwdrivers used across electrical, HVAC, and plumbing trades.
Insert bits should be seated fully into the bit holder or chuck before applying torque. Inspect bits for wear or deformation before each use, as damaged bits can strip fastener heads. Bits are not designed for use beyond their rated drive size. Dispose of worn bits rather than continuing to use them on critical fasteners.
