Product Description

The WERA 05066520001 is a T27 tamperproof Torx screwdriver bit with a 1/4 inch hex shank designed for use with standard 1/4 inch drive bit holders and power tools. The security pin in the tip engages T27 tamper-resistant Torx fasteners found on equipment panels, assemblies, and enclosures where tamper-deterrent hardware is specified. At 1 inch overall length, this bit fits compact bit holders and inline drivers commonly used in tight spaces. Weighing 0.1 pounds, it is a lightweight, single-piece bit suitable for daily trade use in HVAC, electrical, and general mechanical service work.

This bit is suited for service technicians and installers who regularly encounter tamper-resistant fasteners on equipment covers, control panels, motor assemblies, and access doors.

The 1/4 inch hex drive makes it compatible with standard bit holders, extension bars, and 1/4 inch drive power tool chucks.

Ensure the bit is fully seated in the bit holder before applying torque to avoid cam-out or tip damage.
