Proto JSCVM27 Combination Wrench 27 Mm Ratcheting Chrome

Product Description

The PROTO JSCVM27 is a 27 mm ratcheting combination wrench built for trade professionals who need reliable torque in tight service environments. The 12-point box end accepts fasteners at multiple engagement angles, reducing the arc required for each stroke. A 15-degree offset head reduces knuckle clearance issues in confined spaces. At 14-1/8 inches overall length, this wrench delivers useful leverage for loosening and torquing standard metric fasteners. The chrome finish provides corrosion resistance for long service life in demanding shop and field conditions. This wrench is tether capable, making it suitable for elevated work environments where dropped-tool hazards must be controlled.

The JSCVM27 fits common applications in industrial maintenance, mechanical contracting, heavy equipment service, and facilities work where 27 mm metric fasteners are encountered. The ratcheting box end with reversing function allows continuous fastener rotation without repositioning the wrench, speeding up repetitive work on flanges, pumps, compressors, and similar equipment. The straight handle supports standard palm and palm-ratchet technique. It meets ASME B107.100-2010 standards and carries a lifetime warranty from PROTO.

• Ratcheting and reversing box end eliminates the need to reposition the wrench between strokes
• 15-degree offset head angle provides clearance in confined or recessed fastener locations
• 12-point box end engages fasteners at 30-degree intervals for use in restricted swing situations
• Tether capable design supports compliance with dropped-object prevention requirements at height
• Chrome finish offers corrosion resistance for extended service life
• Meets ASME B107.100-2010 standard for combination wrenches

Compatibility

Designed for use with 27 mm metric fasteners in standard hex configurations. Compatible with applications requiring ASME B107.100-2010 compliant combination wrenches.

Installation Notes

This wrench is installed and operated by licensed mechanics, millwrights, pipefitters, and maintenance technicians. Ensure the correct fastener size is confirmed before applying torque to avoid rounding. When working at elevation, attach the wrench to an approved tether point before use to satisfy dropped-tool safety requirements. Do not use extension bars or cheater pipes on the handle, as this exceeds the design load of the tool.
