Narrowed diameter stretches to the base of the socket on small, deep-length sizes. This provides greater reach into tight, recessed areas.
Provides an exact fit and maximum contact for hex fasteners
Radiused corners prevent fastener round-off by applying force to a fastener’s flat sides, rather than its corners.
Meets minimum value of 1.2 times the ANSI standard for Proof Torque. Verified by a single-cycle test that applies torque until specified value is reached without failure or permanent deformation.
