Wiha 71704 Ball End Hex Insert Bit 1/4 in Drive

Product Description

The WIHA 71704 is a ball end hex screwdriver insert bit designed for use with 1/4 inch hex drive power tools, impact drivers, and bit holders. The ball end tip allows engagement with fasteners at angles up to approximately 25 degrees off-axis, making it practical in tight or obstructed workspaces. At 1 inch overall length, this is a standard short-form insert bit suited for use in bit holders, extension bars, and direct-chuck tool adapters. It is sized for Number 8 cap screws and handles standard hex socket fasteners. Electricians, HVAC technicians, and general mechanical contractors commonly use bits in this format for panel assembly, equipment installation, and fastener-dense service work.

This insert bit is intended for professional trade use where access to fasteners is limited or where angle driving is required. The 1/4 inch drive size is the most common standardized bit shank in the trade, compatible with the vast majority of cordless drivers, impact drivers, and manual bit holders used in the field. The Number 8 cap screw sizing covers a wide range of machine screws common in electrical enclosures, HVAC equipment housings, and light mechanical assemblies. It is packaged individually as a single piece.

Installation Notes

Insert bits should be seated fully into the bit holder or tool chuck before applying torque. Inspect the bit tip for wear or rounding before each use, as a damaged tip can strip fastener heads. Always ensure the tool is powered down or the driver is in the locked position when changing bits. Follow applicable NEC or equipment manufacturer guidelines when working on energized or sensitively toleranced assemblies.
