Proto jscv24 Ratcheting Combination Wrench 3/4 in

Product Description

The PROTO jscv24 is a spline ratcheting combination wrench built for trade professionals who need maximum torque transfer on hex, 4-point, 6-point, 12-point, and spline fasteners without risking fastener damage. The open end handles standard SAE work while the spline box end delivers more torque than a conventional 12-point design, reducing the chance of rounding fastener heads under load. Constructed from alloy steel with a black chrome finish, the wrench measures 9.75 inches overall and weighs 0.48 pounds. The reversing ratchet mechanism allows the box end to rotate freely in one direction without lifting the wrench off the fastener, speeding up work in tight spaces.

This wrench is designed for SAE fastener work in industrial, mechanical, and field-service applications. The 3/4-inch head size covers common heavy-duty fasteners found in HVAC equipment, plumbing infrastructure, and general mechanical assemblies. The 15-degree head offset and 15-degree opening angle improve access in confined areas. With a minimum arc swing of 5 degrees, the jscv24 is well-suited for restricted-clearance work where full handle rotation is not possible. The tether-capable design supports use in elevated or safety-critical work environments.

Key Features

• Spline box end engages 4-point, 6-point, 12-point, and spline fasteners without slipping
• Reversing ratchet allows continuous driving without removing the wrench from the fastener
• 15-degree offset head angle improves clearance over fastener obstructions
• 5-degree minimum arc swing enables use in highly restricted spaces
• Alloy steel construction with corrosion-resistant black chrome finish
• Tether-capable design for elevated or fall-hazard work zones
• Meets ASME B107.100-2010 standards

Compatibility

Designed as an SAE-standard ratcheting combination wrench for 3/4-inch fasteners in general mechanical, HVAC, plumbing, and industrial service applications.

Installation Notes

This wrench is intended for use by qualified mechanics and trade technicians. Confirm the correct SAE size before applying torque to avoid fastener damage. Inspect the ratchet mechanism for wear or debris before use in critical applications. When working on pressurized systems or energized equipment, follow all applicable lockout/tagout procedures before service.
