Proto J5222M 22mm 12-point 3/8 Drive Hand Socket

Product Description

The PROTO J5222M is a 22 mm, 12-point hand socket designed for 3/8 inch drive ratchets and extensions. Chrome-plated to resist corrosion and surface wear, this standard-length socket is built for professional use in mechanical, industrial, and maintenance applications. It meets ASME B107.5 standards for hand socket performance and dimensional accuracy. The 12-point design allows engagement at 30-degree increments, giving technicians more flexibility in tight or awkward bolt positions. At 0.22 pounds, it is a lightweight but durable addition to any socket set.

This socket is suited for automotive, HVAC, plumbing, and general mechanical service work where a 22 mm fastener is encountered. Standard-length geometry makes it appropriate for most open-access fastener situations on engine components, equipment panels, pipe fittings, and structural assemblies. It is typically used by licensed mechanics, service technicians, and maintenance professionals working in both shop and field environments.

Installation Notes

This socket is installed and removed by hand or with a 3/8 inch drive ratchet, breaker bar, or torque wrench. Ensure the drive tool and socket are fully seated before applying torque. Inspect the socket for cracks or wear before each use, and do not use damaged sockets. No power tools should be used with hand-rated sockets unless explicitly rated for impact use.
