Wera 05056164001 Torx Insert Bit Set 10 Piece T-8 to T-40

Product Description

The WERA 05056164001 is a 10-piece Torx screwdriver insert bit set designed for fastening and removal of standard Torx fasteners across a wide range of drive sizes. The set spans T-8 through T-40, covering the most common Torx profiles encountered in HVAC equipment, electrical enclosures, and mechanical assemblies. Each bit is 25 millimeters in length, sized for use in standard bit holders, impact-rated handles, or power tool chucks. The full set weighs approximately 0.23 pounds, making it compact enough for a tool pouch or service bag. Technicians working on equipment panels, motor housings, control boards, and access covers will find the full size range practical for a single service call.

This bit set suits trade professionals who regularly encounter Torx fasteners in residential and light commercial applications. HVAC technicians, electricians, and equipment service techs will find the T-10 through T-30 sizes especially common in control panel assemblies, fan housings, and condenser enclosures. The T-8 and T-9 sizes address smaller electronic and motor assembly fasteners, while the T-40 handles heavier structural hardware. The insert format allows fast swapping between a screwdriver handle, bit holder, or drill driver depending on the task.

Installation Notes

Insert bits should be seated fully and securely in the bit holder before applying torque to avoid cam-out or fastener damage. When servicing energized equipment, de-energize and lock out the circuit before removing any panel fasteners, in accordance with applicable NFPA 70E and OSHA lockout/tagout requirements. Inspect each bit tip for wear before use, as worn Torx profiles can strip fastener heads.
