Wiha 74534 T25 Torx Power Screwdriver Bit 2 in 10 Pack

Product Description

The WIHA 74534 is a T25 Torx power screwdriver bit designed for use with power drivers and impact-rated tool systems. Measuring 2 inches in overall length, this bit is made from steel and provides a firm, reliable fit in T25 Torx fastener heads. It ships in a pack of 10, making it a practical restocking choice for technicians who cycle through bits regularly. The 0.25-inch drive size is standard for most power bit holders and quick-change chucks used across HVAC, electrical, and general mechanical service work.

This bit is suited for residential and light commercial service applications where T25 Torx fasteners are common — including HVAC equipment panels, electrical enclosures, and mechanical assemblies. Each pack contains 10 bits, so a single order provides enough quantity for a service van restocking or a small crew. Installation crews and service technicians working in repetitive fastening tasks will find the pack quantity useful for reducing downtime from bit wear.
