Proto JSCV18T Combination Wrench 9/16 in 12-pt Ratcheting

Product Description

The PROTO JSCV18T is a 9/16-inch combination wrench built for trade professionals who need a ratcheting, reversible tool in tight spaces. The 12-point box end engages fasteners at 15-degree head offset, reducing knuckle clearance requirements in confined areas. Constructed from steel with a corrosion-resistant chrome finish, this wrench meets ASME B107.100-2010 standards. Overall length is 7.5 inches and the tool weighs 0.23 pounds, making it a lightweight addition to a service kit. The tether-capable design supports drop-hazard compliance for elevated or safety-critical work environments.

This wrench is suited for mechanical, electrical, plumbing, and HVAC service work where 9/16-inch fasteners are common. The ratcheting box end allows the user to work in restricted spaces without removing and repositioning the tool on each stroke. The reversing function accommodates both tightening and loosening without swapping tools. It is appropriate for both residential service calls and light commercial applications where a compact, corrosion-resistant hand tool is needed.

Installation Notes

This wrench is a general service hand tool requiring no installation. Ensure the correct fastener size is confirmed before applying torque to avoid rounding. When working in elevated or safety-sensitive areas, attach the tether anchor point to an approved lanyard or tool-retention system per applicable jobsite safety requirements. Inspect the ratcheting mechanism for smooth operation before each use.
