Proto J1210SPL Combination Wrench 5/16 Inch 12-point

Product Description

The PROTO J1210SPL is a 5/16-inch combination wrench built for professional trade use in mechanical, industrial, and facility maintenance applications. It features a 12-point box end with a 15-degree offset head angle, allowing access in tight clearances where a straight profile will not seat. The wrench is made from steel with a corrosion-resistant chrome finish and is tether capable, making it suitable for use at height or in tool-control environments. Overall length is 5-27/64 inches. Weight is 0.07 pounds. It meets ASME B107.100 standards and carries a lifetime warranty from the manufacturer.

This wrench is used in general mechanical service, HVAC equipment assembly, plumbing rough-in, electrical panel work, and light industrial maintenance where a compact, short combination wrench is needed. The 5/16-inch size fits common fasteners found on equipment panels, motor mounts, and structural hardware. The tether-capable design meets tool-control requirements for elevated work environments such as rooftop HVAC units, utility platforms, and overhead electrical installations. Straight handle geometry suits confined bolt patterns with limited swing clearance.

Installation Notes

This wrench is used by HVAC technicians, electricians, plumbers, and general maintenance trades. Before beginning fastener work on energized equipment, de-energize circuits and follow applicable lockout/tagout procedures per OSHA 1910.147. When working at height, attach the tether point to an approved lanyard anchor to meet tool-drop prevention requirements. Do not use extension bars or hammers on this wrench to exceed its rated application.
