Proto JSCVM30B Combination Wrench 30 Mm 12 Point

Product Description

The PROTO JSCVM30B is a 30 mm combination wrench designed for heavy-duty fastener work in mechanical, industrial, and trade service environments. It features a 12-point box end and an open end on the opposite side, both sized at 30 mm. The box end is offset at 15 degrees to provide knuckle clearance in tight spaces. Overall length is 15-7/8 inches, giving the leverage needed for large fasteners. The wrench is machined from steel with a chrome finish that resists corrosion and simplifies cleanup. Mechanics, millwrights, pipefitters, and industrial maintenance technicians will find this wrench at home in a professional tool set.

This wrench is suited for use on large hex fasteners found in heavy equipment, industrial machinery, pipeline flanges, and structural assemblies. The 30 mm size is common in metric-spec machinery, commercial vehicle drivetrains, and large-diameter hydraulic and pneumatic fittings. The 15-degree offset box end is especially useful when working in recessed or obstructed bolt patterns where a straight wrench cannot clear surrounding components.

Compatibility

Designed as an OEM-style professional combination wrench for use with 30 mm metric hex fasteners across industrial, mechanical, and trade service applications.

Installation Notes

Select the correct wrench size before applying force to avoid rounding fastener corners. Inspect the wrench for cracks or deformation before each use and do not use a damaged wrench. Do not extend the wrench handle with a pipe or cheater bar, as this can exceed the tool's design load. Keep the chrome surface clean and lightly oiled to maintain finish integrity over time.
