What are the specifications of the PROTO J47055M socket?

How to select the correct PROTO socket size?

To select the correct PROTO socket, match the drive size (1/4 in) to your ratchet or torque wrench, and choose the socket size (5.5 mm) that fits your fastener head. A 6-point socket like the J47055M provides better grip on hex fasteners than a 12-point design, reducing slip risk.
