Product Description

The WIHA 71538 is a T8 Torx insert bit designed for use with 1/4 inch hex drive power tools and manual bit holders. Built from steel, this bit measures 25 millimeters (approximately 1 inch) in overall length and features a 6 millimeter (1/4 inch) hex shank. The T8 Torx profile fits small-head fasteners commonly found in electronics, HVAC control boards, appliance panels, and precision equipment enclosures. This listing includes a package of 10 bits, making it a practical bench or service-van stock item for technicians who work through bits regularly.

The WIHA 71538 suits residential and light commercial service work where T8 Torx fasteners appear on equipment covers, control panels, and electrical enclosures. Electricians, HVAC technicians, and appliance service pros will encounter T8 fasteners on variable-speed drives, thermostat housings, and OEM equipment panels. The 1/4 inch drive format is compatible with standard power drills, impact-rated bit holders, and manual screwdrivers equipped with a 1/4 inch hex chuck or quick-release collar.

Installation Notes

Insert bits should be seated fully into the bit holder before applying torque to avoid cam-out or fastener damage. Confirm the correct Torx size before driving to prevent rounding the fastener head. When servicing energized control panels or electrical enclosures, de-energize and lock out the circuit per NFPA 70E requirements before removing any fasteners. Inspect bits for wear or deformation before each use and replace as needed.
