Proto JSCRM18T Ratcheting Combination Wrench 18 Mm

Product Description

The PROTO JSCRM18T is an 18 mm ratcheting combination wrench built for professional tradespeople who need reliable torque in tight spaces. It features a 15-degree offset head with a 12-point box end and a standard open end, allowing engagement from multiple angles. The straight handle is finished in chrome over steel, providing corrosion resistance for long service life in demanding shop, field, and industrial environments. At 9-5/16 inches overall length and 0.44 pounds, it balances reach with control. Tether-capable design supports use in elevated work areas where dropped-tool protocols are required.

This wrench suits mechanical and industrial maintenance applications where an 18 mm fastener is common, including HVAC equipment assemblies, electrical panel work, pipe flange hardware, and general mechanical service. The ratcheting box end speeds fastener rotation without repositioning the wrench on each stroke. The non-sparking designation does not apply to this tool, so users should follow site-specific procedures in environments where spark risk exists. It meets ASME standards and is appropriate for use by licensed technicians and journeymen across multiple trades.

Installation Notes

This tool is installed and used by licensed technicians and maintenance professionals across mechanical trades. Ensure all equipment is de-energized or de-pressurized before applying torque to any fasteners. Select the correct fastener size before use to avoid rounding hardware. When working at elevation or over open equipment, engage the tether anchor point to comply with dropped-object safety requirements.
