- Large, Stamped Markings – Permanently impressed into the material by a roll-stamp die and as large as possible while still being readable along the socket's curved surface
- Fully Stepped Shoulders - Narrowed diameter stretches to the base of the socket on small sizes. This provides greater reach into tight, recessed areas.
- Exterior and Interior Finishes – The exterior is chrome-plated and the interior is chrome-plated and supplemented with a clear coat or painted finish where needed for full coverage
- 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 – Detent grooves and beveled edges provide a smooth and secure connection with the drive tool
- 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.
