Proto J5430MN Hand Socket 30 Mm 12-point 1/2 Drive

Product Description

The PROTO J5430MN is a 30 mm, 12-point hand socket with a 1/2 inch drive, designed for professional-grade fastener work in mechanical, industrial, and maintenance applications. Built from steel with a chrome-plated finish, this standard-length socket measures 2 inches in overall length. The 12-point configuration engages hex fasteners from multiple contact positions, allowing the technician to work in tight swing arcs. It meets AS4984A, ASME B107.110-2012, and SAE AS955 standards, confirming it is manufactured to recognized industry dimensional and performance tolerances. Licensed tradespeople and skilled mechanics rely on this socket for consistent torque transfer on larger metric fasteners.

This socket is suited for automotive, heavy equipment, HVAC mechanical assemblies, and industrial maintenance tasks requiring a 30 mm metric fastener drive. The 1/2 inch drive interface is compatible with standard 1/2 inch drive ratchets, breaker bars, torque wrenches, and extensions. The standard-length profile keeps it manageable in most engine bay and equipment panel access scenarios without sacrificing depth capacity.

Installation Notes

This socket is installed and removed by hand tool professionals including mechanics, millwrights, and HVAC technicians performing mechanical assembly or disassembly work. Before use, confirm the socket seats fully and squarely on the fastener to prevent rounding. Always relieve system pressure, disable power, or secure equipment before loosening or torquing fasteners on live machinery. Inspect the socket for cracks or chrome flaking before each use and retire any damaged tool from service.
