Wiha 72502 Hex Insert Bit 1/4 in Drive 1/16 in Hex 30 Pc

Product Description

The WIHA 72502 is a hex screwdriver insert bit designed for 1/4 inch drive applications requiring a 1/16 inch hex tip. Made from steel, this insert bit delivers the controlled torque transfer needed for precision fastening tasks in electrical, HVAC, and general mechanical service work. The 72502 ships in a 30-piece quantity, making it well suited for stocking a service van or shop bench. The 1/4 inch drive shank is compatible with standard bit holders and power tool adapters commonly found in trade toolkits. The steel construction provides durability through repeated use in both hand and light power tool applications.

This insert bit fits typical applications where small hex fasteners are encountered in equipment panels, junction boxes, HVAC access hardware, and light mechanical assemblies. The 1/16 inch hex size addresses fine-thread set screws and small fasteners found in residential and light commercial equipment. Electricians, HVAC technicians, and plumbers will find this size useful for service calls that require accessing or securing small hex-drive hardware. The 30-piece package supports bulk stocking for service departments or multi-tech operations.

Installation Notes

Insert bits should be seated fully into the bit holder before applying torque to avoid cam-out or tip damage. Inspect the bit tip for wear or rounding before each use, particularly when working with precision fasteners in electronic or control panel assemblies. Replace worn bits rather than forcing engagement, as a damaged tip can strip fastener heads and complicate removal.
