Wera 05135074001 Hex Insert Bit 1/4 in Drive 5/32 in Hex

Product Description

The WERA 05135074001 is a hex screwdriver insert bit designed for use with 1/4 inch hex drive power tools and manual bit holders. The bit drives 5/32 inch hex fasteners and measures 1 inch in overall length, making it suitable for standard-depth insert bit applications. It is a straight-shank, non-ball-end design, meaning full engagement with the fastener socket is required for torque transfer. This bit is appropriate for use by electricians, HVAC technicians, plumbers, and general mechanical tradespeople who regularly drive hex socket fasteners during equipment installation or service work.

This insert bit fits into any standard 1/4 inch hex drive quick-change chuck, bit holder, or screwdriver handle. The 1 inch overall length is the industry-standard insert bit format, compatible with magnetic bit holders, extension bars, and inline bit-drive tools. It is well suited for repetitive fastener driving in tight spaces where a compact bit is needed over a longer bit or full hex key. Typical applications include equipment panel assembly, electrical enclosure work, and mechanical fastener service on HVAC and refrigeration equipment.

Installation Notes

This bit is installed and removed by hand from a compatible 1/4 inch hex drive chuck or bit holder. Ensure the bit is fully seated in the holder before applying torque to avoid cam-out or bit ejection. Do not use with impact drivers unless the bit is rated for impact use. Verify the 5/32 inch hex size matches the fastener before driving to prevent fastener or bit damage.
