Proto J5215M 15mm 12-point 3/8 Drive Hand Socket

Product Description

The PROTO J5215M is a 15 mm, 12-point hand socket designed for 3/8 inch drive ratchets, breaker bars, and extensions. Manufactured from alloy steel with a chrome-plated finish, this standard-length socket measures 1.125 inches overall. The 12-point design allows engagement at every 30 degrees of rotation, giving technicians more working positions in tight spaces. It meets ASME B107.5 standards for hand socket dimensions and strength. Licensed mechanics, HVAC technicians, and plumbers reach for this socket when working on fasteners in confined areas where a 15 mm hex head is the target size.

This socket fits standard 3/8 inch drive tool setups and is suited for general mechanical service work across residential, commercial, and light industrial settings. Typical applications include equipment servicing, panel fastener removal, and mechanical assembly work where a 15 mm fastener is present. The standard-length body keeps it compatible with common socket organizers and drive extensions used in everyday service kits.

Installation Notes

Installation of this socket requires a 3/8 inch drive handle or ratchet. Ensure the socket is fully seated on both the drive tool and the fastener before applying torque. Do not use impact drivers with this hand socket, as it is not rated for impact service. Inspect for cracks or deformation before each use and replace if the chrome finish shows signs of heavy wear or the socket walls are damaged.
