Proto J5416MN 16mm 12-point 1/2 Drive Hand Socket

Product Description

The PROTO J5416MN is a 16 mm, 12-point hand socket designed for use with a 1/2 inch drive ratchet or breaker bar. Constructed from chrome-plated steel, it delivers reliable corrosion resistance and a clean surface finish suitable for professional shop environments. The standard-length design measures 1-45/64 inches overall, fitting typical fastener access scenarios without the added reach of a deep socket. It meets AS4984A, ASME B107.110-2012, and SAE AS955 standards, making it appropriate for both general mechanical work and applications requiring certified tooling. This socket is suited for use by automotive technicians, industrial mechanics, and maintenance professionals.

This socket is used in automotive, industrial, and mechanical maintenance applications where 16 mm fasteners are common. The 12-point design engages hex fasteners at multiple contact positions, allowing easier socket placement in tight quarters. Standard-length sockets like the J5416MN are the everyday workhorse in most socket sets, used on engine components, chassis hardware, and general assembly work. It is compatible with any 1/2 inch drive tool including ratchets, torque wrenches, and impact-rated extensions where the socket is rated for hand use.

Compatibility

Designed as an OEM-style hand socket for use with any standard 1/2 inch drive ratchet, breaker bar, torque wrench, or extension. Note: this socket is not tether capable.

Installation Notes

This socket is installed and removed by hand and is intended for use by mechanics and maintenance technicians. Always ensure the drive tool and socket are fully seated before applying torque. Do not use this socket with pneumatic or hydraulic impact tools unless the tool and socket are both rated for impact use. Inspect the socket for cracks or deformation before each use and replace if wear is visible.
