Proto JSCVM12F 12mm Ratcheting Combination Wrench

Product Description

The PROTO JSCVM12F is a 12 mm ratcheting combination wrench built for professional tradespeople who need reliable, fast-turning capability in tight spaces. Constructed from steel with a corrosion-resistant chrome finish, this wrench features a flexible head with a 15-degree offset angle and a 12-point box end. Overall length is 5 inches. The ratcheting mechanism eliminates the need to reposition the wrench on every stroke, reducing fatigue during repetitive fastening work. Tether-capable design supports use in elevated or safety-critical work environments where dropped tools are a hazard. Meets ASME standards.

The JSCVM12F is suited for mechanical, electrical, plumbing, and HVAC service work where metric fasteners are standard. The 12 mm head size is common in HVAC equipment panels, electrical enclosures, and plumbing fixture assemblies. The straight handle and flexible head combination allows access to fasteners in recessed or obstructed locations. This wrench is appropriate for both shop use and field service kits. It is not rated for non-sparking applications.
