Wiha 71537 T7 Torx Insert Bit 1/4 Inch Drive 10-pack

Product Description

The WIHA 71537 is a T7 Torx insert bit designed for use with 1/4 inch hex drive power tools and bit holders. Built from steel, this bit measures 25 millimeters (approximately 1 inch) in overall length, placing it in the standard insert bit category suited for most magnetic bit holders and quick-change chucks. The T7 Torx profile is a precision fit for small-fastener applications commonly found in HVAC equipment panels, electrical enclosures, and light commercial equipment assemblies. This package contains 10 bits, making it a practical shop or service-van restocking option for trades that encounter T7 fasteners regularly.

The WIHA 71537 is well suited for service technicians who work on equipment with small-profile Torx fasteners, including control boards, access panels, and electronics housings in HVAC, electrical, and light mechanical applications. The 1/4 inch hex shank is compatible with standard power drivers, impact-rated bit holders, and manual screwdrivers equipped with a 1/4 inch hex socket. The 10-piece pack supports high-usage environments where bit wear or loss is a routine consideration.

Installation Notes

Insert bits should be seated fully into the bit holder before applying torque to prevent cam-out or fastener damage. Use the correct T7 profile exclusively on T7 fasteners — mismatched Torx sizes can strip fastener heads. When servicing energized equipment, power down and follow applicable NFPA 70E lockout/tagout procedures before accessing fastened panels or enclosures.
