Wiha 70160 T27 Tamperproof Torx Bit 1/4 in Drive 10-pack

Product Description

The WIHA 70160 is a T27 tamperproof Torx screwdriver bit designed for use with 1/4 inch hex drive tools and bit holders. Built from steel, this security bit features the center-pin bore required to engage tamper-resistant Torx fasteners found in HVAC equipment panels, electrical enclosures, and commercial appliances. The overall length is 25 millimeters (approximately 1 inch), making it compatible with standard 1/4 inch quick-change bit holders and drivers. Each order is fulfilled in a quantity of 10 bits, providing a practical working supply for field techs and service crews who cycle through security bits regularly.

Tamperproof Torx bits are commonly required when servicing equipment panels, control enclosures, and access covers that use security fasteners to deter unauthorized access. The T27 size is frequently encountered on HVAC equipment cabinets, commercial refrigeration units, and electrical distribution panels. This bit is suited for licensed technicians who routinely access manufacturer-secured enclosures during maintenance, inspection, or component replacement work.

Installation Notes

Ensure the driving tool is de-energized or disconnected from power before accessing any electrical or HVAC enclosure secured with tamperproof fasteners. Seat the bit fully into the fastener head before applying torque to avoid stripping the security recess. Inspect bits regularly for wear and replace when the drive tip shows rounding or deformation. Follow applicable electrical and mechanical codes when opening manufacturer-secured equipment panels.
