Wiha 70148 T25 Tamperproof Torx Bit 1/4 in Drive 10-pack

Product Description

The WIHA 70148 is a T25 tamperproof Torx screwdriver bit designed for use with 1/4 inch hex drive tools. Built from steel, this security bit features a center-pin bore that engages tamper-resistant Torx fasteners found in restricted-access panels, equipment enclosures, and specialty hardware. The overall length is 25 millimeters (approximately 1 inch), making it compatible with standard bit holders and quick-change chucks. Each order includes 10 bits, providing enough supply for jobsite use or restocking a service van. HVAC technicians, electricians, and plumbers regularly encounter tamper-resistant fasteners on OEM equipment covers and control panels where this bit size is a common requirement.

The 70148 is suited for service and maintenance work on residential and light commercial equipment where T25 tamper-resistant Torx fasteners are used. Typical applications include accessing motor housings, control board covers, appliance panels, and enclosures secured with security Torx hardware. The 1/4 inch hex shank fits standard power drivers, impact drivers with bit holders, and manual bit-handle tools used across HVAC, electrical, and plumbing trades.

Installation Notes

Installation and removal of tamper-resistant fasteners should be performed by a qualified trade professional familiar with the equipment being serviced. Always de-energize and lock out electrical equipment before accessing control panels or enclosures. Ensure the bit is fully seated in the fastener before applying torque to avoid stripping the security recess. Worn or damaged bits should be replaced rather than reused to prevent fastener damage.
