Wiha 71604 IP4 Torx Plus Insert Bit 1/4 in Drive 10-pack

Product Description

The WIHA 71604 is an IP4 Torx Plus insert bit designed for use with 1/4 inch hex drive screwdrivers, bit holders, and power tool adapters. At 25 millimeters (approximately 1 inch) overall length, this is a standard insert-style bit suited for tight-access fastening tasks in HVAC equipment panels, electrical enclosures, and precision assemblies that use tamper-resistant Torx Plus fasteners. The IP4 drive size is common on small fasteners found in controls, circuit board housings, and light-gauge sheet metal components. The bit ships in a pack of 10, making it practical for service vans and shop stock where bit wear or loss is a factor.

Torx Plus bits are required wherever manufacturers specify IP-series tamper-resistant fasteners instead of standard TX-profile Torx. These fasteners appear frequently in HVAC control board enclosures, variable-speed drive housings, and electronic equipment assemblies across residential and light commercial applications. The 1/4 inch hex shank fits directly into standard bit holders, magnetic nut drivers, and most cordless screwdriver chucks without an adapter. The 10-piece pack quantity supports service technicians who maintain a working supply of commonly used bits on the truck or bench.

Installation Notes

Insert bits should be seated fully into the bit holder before applying torque to avoid cam-out or bit damage. When servicing energized electrical or HVAC equipment, de-energize the system and follow applicable NFPA 70E or NEC safe-work practices before opening enclosures. IP-profile Torx Plus bits are not interchangeable with standard TX Torx fasteners — confirm the fastener profile before use to avoid fastener or bit damage.
