Proto J5336B Deep Hand Socket 1-1/8 in 12-point

Product Description

The PROTO J5336B is a deep hand socket designed for professional-grade fastener work in demanding trade environments. Built from alloy steel with a black oxide finish, this socket provides reliable grip on 1-1/8 inch fasteners where standard-depth sockets cannot reach. The 12-point configuration allows engagement from multiple angles, reducing repositioning time on confined or recessed fasteners. It accepts a 1/2 inch drive and measures 3-1/4 inches in overall length. Licensed tradespeople working on HVAC equipment, plumbing systems, electrical panels, and mechanical assemblies will find this socket well-suited to production and service applications alike.

This deep socket is appropriate for both residential and commercial service work. It is commonly used in mechanical rooms, rooftop equipment, pump rooms, and panel installations where longer fasteners or bolt protrusion requires additional socket depth. The 1/2 inch drive makes it compatible with standard ratchets, breaker bars, and torque wrenches found in most trade toolkits. Meets ASME B107.1 standards for hand tools used in professional settings.

Installation Notes

This socket is intended for use by licensed tradespeople and qualified mechanics. Always ensure the drive tool and socket are fully engaged before applying torque to prevent slippage or fastener rounding. Inspect the socket for cracks or wear before each use. Do not use hand sockets with impact drivers unless the tool is rated for impact use.
