The bit measures 2.75 inches overall length and is constructed from steel for durability under repeated drive cycles. With a 0.25-inch drive size, it fits standard power bit holders and quick-change chucks. The non-magnetic design suits applications where magnetic interference is a concern.

T20 Torx bits are commonly used in commercial and residential electrical and HVAC work where equipment manufacturers specify Torx fasteners on enclosures, control boards, and access panels. The 2.75-inch overall length provides additional reach in recessed or obstructed fastener locations.

Installation Notes

Installation of this bit requires a power tool or hand driver with a 0.25-inch quick-change or standard hex chuck. Ensure the tool is powered off and the trigger is locked before changing bits. Inspect the bit tip for wear before each use, as damaged Torx tips can strip fastener heads. Follow applicable NEC or equipment manufacturer guidelines when servicing electrical enclosures or panels.
