Wiha 75644 Screwdriver Insert Bit 5/64 Hex 30mm 10-pack

Product Description

The WIHA 75644 is a 5/64-inch hex screwdriver insert bit with a 30 mm overall length, sold in a pack of 10. Insert bits are short-form driver bits designed for use with bit holders, power screwdrivers, and impact-rated handles where a standard full-length bit is not practical. The 75644 suits applications requiring precise hex drive engagement in confined spaces or repetitive fastening tasks. Licensed electricians, HVAC technicians, and general trade professionals reach for insert bits like this when working with equipment panels, terminal blocks, and fixture assemblies that use hex socket fasteners.

This insert bit is appropriate for light-duty to medium-duty hex driving tasks in residential and commercial service environments. The compact 30 mm length fits standard 1/4-inch bit holders and quick-change chucks. It is well suited for panel work, equipment installation, and maintenance scenarios where a 5/64-inch hex drive is the required fastener interface. The 10-piece pack format supports service vans and tool kits where bit loss and wear are routine consumable concerns.

Installation Notes

Insert bits should be seated fully in the bit holder before applying torque to prevent cam-out or bit ejection. Inspect the hex tip for wear before each use, as a worn tip can damage fastener heads. Replace bits showing rounding or chipping at the drive tip. Follow applicable NEC or equipment manufacturer guidelines when working inside energized panels — always de-energize and verify lockout/tagout before beginning fastener work on electrical equipment.
