The PROTO JSCV12S is a 3/8 inch ratcheting combination wrench built for trade and industrial use. It features a 12-point box end with a 15-degree offset head angle, a straight handle, and a chrome finish over steel construction. Overall length is 3-3/4 inches, making it a compact tool suited for confined-space fastener work. The reversing ratchet mechanism allows direction changes without repositioning on the fastener. Corrosion-resistant per its chrome finish, the JSCV12S is tether capable, supporting tool-tethering programs in elevated or safety-critical work environments. It meets ASME standards for combination wrenches.
This wrench is designed for use by electricians, HVAC technicians, pipefitters, plumbers, and general maintenance professionals working on mechanical assemblies that require precise torque in tight spaces. The ratcheting box end is particularly useful in areas where a full swing arc is not possible. The 3/8 inch size fits common fasteners found in equipment panels, compressor housings, valve assemblies, and conduit fittings. Its compact overall length makes it a reliable secondary wrench for detail work alongside larger drive tools.
Designed as a standard 3/8 inch combination wrench replacement or addition for professional tool sets requiring an ASME-compliant ratcheting wrench in that drive size.

Use appropriate personal protective equipment when working in environments where tool-tethering is required. Do not use as a striking tool or apply pipe extensions to the handle.
