Proto JSCVM18T 18mm Ratcheting Combination Wrench

Product Description

The PROTO JSCVM18T is an 18 mm ratcheting combination wrench designed for professional tradespeople who need reliable torque transfer in tight or repetitive-fastener applications. Built from steel with a chrome finish, this wrench features a 15-degree offset head, 12-point box end, and a reversing ratchet mechanism that allows directional changes without repositioning on the fastener. At 9-5/16 inches overall length, it delivers the leverage and reach typical of standard combination wrench service. The ASME B107.100-2010 compliance confirms it meets recognized performance and dimensional standards for hand tools in industrial and trade use.

This wrench is suited for mechanical, plumbing, and HVAC service work where 18 mm fasteners appear on equipment, piping connections, or structural hardware. The ratcheting action makes it especially useful in confined spaces where a full swing arc is not available. The tether-capable design supports use in elevated work environments such as rooftop HVAC installations, mechanical penthouses, or any application where dropped-tool protocols are in place. The straight handle and corrosion-resistant chrome finish make it practical for both shop and field conditions.

Key Features

• Ratcheting and reversible box end for single-position fastener driving
• 15-degree offset head reduces knuckle clearance issues in tight spaces
• 12-point box end engages standard hex fasteners at multiple entry angles
• Tether capable for dropped-object prevention in elevated work environments
• Chrome finish provides corrosion resistance for field and shop use
• Meets ASME B107.100-2010 hand tool standard

Compatibility

Designed for use with 18 mm hex fasteners across mechanical, HVAC, plumbing, and general industrial service applications.

Installation Notes

This wrench is installed and used by licensed HVAC technicians, pipefitters, plumbers, and general mechanical tradespeople. Ensure the work area is de-energized or depressurized as required before applying torque to any system fastener. When using in elevated locations, attach a tether to the wrench lanyard point before beginning work to comply with dropped-object prevention requirements. Inspect the ratchet mechanism for smooth engagement before each use.
