Permanently impressed into the material by a roll-stamp die
As large as possible while still being readable along the socket's curved surface
Clearly visible size numbers with extra-deep outline

Fully Stepped Shoulders

Narrowed diameter stretches to the base of the socket on small, deep-length sizes. This provides greater reach into tight, recessed areas.

Exterior and Interior Finishes

Chrome-plated exterior is highly corrosion resistant and wipes clean to a mirror finish
Interior is protected against rust with clear coat, rather than commonly-used metallic paint

6-Point Socket Opening

Provides an exact fit and maximum contact for hex fasteners.

Prevents Fastener Round-Off

Radiused corners prevent fastener round-off by applying force to a fastener's flat sides, rather than its corners.

Secure Drive Tool Engagement

Four detent grooves provide a secure connection with the retaining ball of a drive tool
Beveled inner rims help guide the socket onto other tools

High Torque Strength

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.
