Proto J5207MN 7mm 12-point 3/8 Drive Hand Socket

Product Description

The PROTO J5207MN is a 7 mm, 12-point intermediate hand socket designed for use with a 3/8-inch drive ratchet or breaker bar. Built from polished steel to ASME B107.21 standards, this socket delivers reliable torque transfer in tight or repetitive fastening tasks. The standard-length profile measures 1-17/64 inches overall, keeping it compact enough for general-purpose hand tool applications. It is a straightforward, single-purpose socket suited for automotive, mechanical, and industrial service work where a 7 mm fastener is common. Licensed technicians and professional mechanics are the primary users, though skilled trades across multiple disciplines will recognize this as a dependable shop staple.

This socket fits standard 3/8-inch drive tool sets and is appropriate for both residential shop environments and light commercial service applications. The 12-point configuration allows engagement from multiple angles, making it useful in confined spaces where full ratchet swing is limited. Typical use cases include fastener work on engine components, equipment panels, and mechanical assemblies requiring a 7 mm drive socket of standard length.

Installation Notes

This socket is installed and operated by mechanics, automotive technicians, and general trade professionals. Ensure the socket is fully seated on the fastener head before applying torque to prevent rounding. Inspect the socket and drive connection for wear before use, and do not use hand sockets with impact drivers unless the socket is rated for impact use.
