Product Description

The WIHA 72512 is a hex screwdriver insert bit designed for use with 1/4 inch drive bit holders, power tools, and manual screwdrivers that accept standard insert bits. With a 7/32 inch hex profile and an overall length of 25mm, this bit is suited for fastening and driving hex socket fasteners in tight or standard-clearance applications. The package includes 30 bits, making it a practical choice for service vans, shop benches, or job site kits where high-turnover tooling is common. No ball end is included on this design, providing a solid, full-engagement fit on standard hex fasteners.

This insert bit is used across trades that regularly encounter hex drive fasteners, including HVAC technicians, electricians, plumbers, and general mechanical service professionals. The 1/4 inch drive sizing is the most widely used insert bit format, compatible with the majority of bit holders, magnetic extensions, and impact-rated adapters found in trade tool kits. The 30-piece quantity per package makes it well suited for stocking service trucks or replenishing shop supplies.

Compatibility

Installation Notes

Insert bits should be seated fully into the bit holder before applying torque to avoid cam-out or tip damage. Verify the hex size matches the fastener recess before driving to prevent fastener or bit damage. When used with power tools, confirm the holder is rated for rotary or impact use as appropriate for the application.
