Proto JSCVM30 30 Mm Ratcheting Combination Wrench

Product Description

The PROTO JSCVM30 is a 30 mm ratcheting combination wrench built for professional tradespeople who need reliable torque delivery in tight or repetitive-fastening applications. The wrench features a 15-degree offset box end that improves knuckle clearance in confined spaces, a straight handle, and a reversing ratchet mechanism that eliminates repositioning between strokes. At 15.875 inches overall length, it provides substantial leverage for larger fasteners. Constructed from chrome-finished steel, the JSCVM30 meets ASME B107.100-2010 standards and is covered by a lifetime warranty.

The JSCVM30 is suited for mechanical, electrical, and industrial maintenance work where 30 mm fasteners appear on heavy equipment, HVAC compressor assemblies, large conduit fittings, structural hardware, and commercial plumbing connections. The tether-capable design makes it appropriate for elevated work environments where tool-drop prevention is required by site safety protocols. The 12-point box end engages standard hex fasteners at multiple positions, useful when swing arc is limited.

Key Features

• Ratcheting and reversing box end eliminates handle repositioning between strokes
• 15-degree offset box end provides knuckle clearance in restricted work areas
• 12-point box end engages fasteners at 30-degree increments for use in tight swing arcs
• Tether-capable design meets elevated-work tool-retention requirements
• Chrome finish over steel construction provides corrosion resistance
• Meets ASME B107.100-2010 standards and backed by a lifetime warranty

Compatibility

Designed for use with 30 mm hex fasteners on heavy equipment, industrial machinery, and commercial mechanical systems where a standard or ratcheting combination wrench is specified.

Installation Notes

A licensed mechanic or qualified tradesperson should select fastener engagement direction on the reversing mechanism before applying torque. Confirm the box or open end is fully seated on the fastener before loading the wrench to prevent rounding. Do not use extension bars or cheater pipes on this wrench. Inspect the ratchet mechanism for debris or wear periodically, especially in environments with metal chips or grit.
