Proto JSCV14F Combination Wrench 7/16 Inch Ratcheting

Product Description

The PROTO JSCV14F is a 7/16-inch combination wrench designed for fastener work in tight or repetitive-torque applications. It features a 12-point box end with a ratcheting mechanism, a 15-degree head offset, and a straight handle — a layout that reduces repositioning time when driving fasteners in confined spaces. The wrench is made from steel with a corrosion-resistant chrome finish and is tether-capable, making it suitable for work at height or on elevated equipment where dropped tools are a hazard. Overall length is 5 inches and the head thickness is 5/16 inches. Weight is 0.15 pounds. It meets ASME standards.

This wrench fits into general mechanical and maintenance work across HVAC, plumbing, electrical, and industrial service trades. The 7/16-inch size is common for small-fastener applications including equipment panel hardware, bracket fasteners, and utility connections. The ratcheting box end is particularly useful when wrench swing is limited, such as inside air handler cabinets, electrical enclosures, or near pipe runs. The tether-capable design addresses tool-drop safety requirements on elevated platforms and rooftop equipment.

Key Features

• Ratcheting 12-point box end reduces repositioning in restricted swing situations
• 15-degree head offset for improved clearance over fastener heads
• Tether-capable design meets tool-drop safety requirements for elevated work
• Corrosion-resistant chrome finish for durability in field conditions
• Meets ASME standards for combination wrenches
• Compact 5-inch overall length for work in tight spaces

Compatibility

Designed as a standard 7/16-inch combination wrench suitable for hex fasteners in residential and commercial mechanical service applications.

Installation Notes

This wrench is intended for use by qualified trade professionals working on mechanical fasteners. Before servicing any equipment, power down electrical systems and isolate any pressurized lines per applicable codes. When working at height, attach a tether to the wrench anchor point and a secure anchor on the tool belt or structure before use. Do not use this wrench as a substitute for a torque wrench where specific fastener torque values are required.
