Proto J5213M 13 Mm 3/8 Drive 12-point Chrome Hand Socket

Product Description

The PROTO J5213M is a 13 mm, 12-point hand socket designed for professional fastener work in mechanical, HVAC, plumbing, and electrical service applications. Built to a 3/8 inch drive, this standard-length socket features a chrome-plated finish for corrosion resistance and easy cleanup in shop environments. It meets ASME B107.5 standards, confirming dimensional and strength compliance expected by trade professionals. The 12-point design provides more contact positions around the fastener, useful when working in confined spaces where swing arc is limited. Intended for use with standard 3/8 inch drive ratchets, extensions, and torque wrenches.

This socket suits residential and commercial maintenance tasks across multiple trades. HVAC technicians reach for it during equipment panels, blower assemblies, and condenser work. Plumbers and pipefitters use it on fixture hardware and access covers. Electricians and general contractors use 13 mm sockets routinely on equipment mounting hardware and enclosures. Its standard length makes it a core bench and field socket for any technician carrying a 3/8 inch drive set.

Compatibility

Designed for use with any standard 3/8 inch drive ratchet, breaker bar, extension, or torque wrench accepting 3/8 inch drive sockets.

Installation Notes

Ensure the drive tool is rated for the torque being applied before use. Inspect the socket for cracks or wear before each use and replace if damage is found. Do not use hand sockets with impact drivers unless the socket is specifically rated for impact use. Store in a dry environment to maintain the chrome finish.
