Large, Stamped Markings

  • 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

Exterior + 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

12-Point Socket Opening

Get more access positions for multiple types of 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 1.3 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.
