Proto JSCVM27T Combination Wrench 27 Mm Ratcheting

Product Description

The PROTO JSCVM27T is a 27 mm ratcheting combination wrench built for professional trade use in mechanical, industrial, and maintenance applications. It features a 12-point box end with a 15-degree offset head and a reversing ratchet mechanism, allowing fastener engagement in tight quarters without repositioning the tool. The wrench is machined from steel with a chrome finish that provides corrosion resistance. Overall length is 14.125 inches and weight is 1.47 pounds. It meets ASME B107.100-2010 standards and is tether capable, making it appropriate for work at height or in environments where dropped tools are a hazard.

This wrench is suited for heavy equipment maintenance, industrial machinery service, pipeline work, and structural assembly where 27 mm fasteners are common. The straight handle and offset box end allow clearance over bolt flanges and recessed fastener locations. The reversing ratchet eliminates the need to break and reseat the box end between turns, improving efficiency on repetitive fastener work. Tether capability supports compliance with dropped-object prevention programs on elevated work sites or in facilities with strict tool-control requirements.

Key Features

• Ratcheting and reversing 12-point box end for efficient fastener driving without repositioning
• 15-degree offset head angle provides clearance over obstructions and raised surfaces
• Tether capable design supports dropped-object prevention programs
• Chrome finish over steel construction provides corrosion resistance
• Meets ASME B107.100-2010 standard for combination wrenches
• 14.125-inch overall length delivers leverage for 27 mm fastener applications

Compatibility

Designed as an OEM-style professional-grade combination wrench for use with 27 mm fasteners in industrial, mechanical, and maintenance trade applications.

Installation Notes

Mechanical technicians and industrial maintenance professionals should inspect the ratchet mechanism for proper engagement before applying torque. Do not use extension bars or pipe sleeves to increase handle leverage beyond the designed length, as this may damage the ratchet mechanism or cause fastener rounding. When using in tethered applications, attach an approved lanyard to the tether point before beginning work and verify the lanyard rating meets site dropped-object requirements.
