T45 Long/Deep Reach Impact Torx Socket, 1/2" Drive

Brief Overview

This T45 impact-rated Torx socket delivers professional fastening capability for 1/2" drive pneumatic and electric tools. The extended 78mm reach design positions the driver precisely in confined spaces, reducing angle stress and improving access to recessed fasteners. Built from chromium-molybdenum steel with impact-grade finishing, it handles sustained torque loads up to 103.49 Nm without deformation or bit slippage. Pair this with complementary T40 and T50 impact sockets to cover your medium-duty Torx fastening range, or expand further with our comprehensive socket bit sets for complete assembly coverage.
