Proto JSCVM16T 16mm Ratcheting Combination Wrench

Product Description

The PROTO JSCVM16T is a 16 mm ratcheting combination wrench built for professional tradespeople who need reliable torque control in tight, high-cycle applications. The 12-point box end engages fasteners with precision, while the reversing mechanism lets technicians change drive direction without removing the wrench from the fastener. The 15-degree offset head provides clearance in confined workspaces. At 8.19 inches overall length and 0.33 pounds, this wrench balances reach with control. Chrome finish provides corrosion resistance for long service life in demanding environments.

This wrench suits a wide range of commercial and industrial maintenance tasks, including mechanical, electrical, and HVAC equipment assembly and service. The tether-capable design makes it appropriate for at-height or elevated work where tool drop is a safety concern. Straight handle geometry keeps it compatible with standard hand-tool workflows. It meets ASME B107.100-2010 standards, making it suitable for facilities and contractors with compliance requirements for hand tools.

Installation Notes

Licensed mechanics and trade technicians should confirm fastener size before use to avoid fastener rounding. Always de-energize or lock out equipment before applying torque to fasteners on live systems. When used in elevated or overhead applications, attach the tether point to an approved tool lanyard per applicable fall-protection requirements. Inspect the wrench for cracks or worn ratchet pawls before each use.
