Proto J1217MES Combination Wrench 17 Mm 12-point

Product Description

The PROTO J1217MES is a 17 mm combination wrench built for professional trade use in mechanical, HVAC, plumbing, and industrial service applications. It features a 12-point box end with an offset head profile, giving technicians better knuckle clearance in tight or recessed fastener locations. The wrench is machined from steel with a chrome finish that resists corrosion and simplifies cleanup after use. At 5-1/16 inches overall length, it is compact enough for close-quarters work while providing adequate leverage for 17 mm fasteners. Non-ratcheting design keeps the mechanism simple and durable under heavy use.

This wrench fits typical service scenarios involving 17 mm hex fasteners found on equipment panels, pipe flanges, valve packing nuts, conduit fittings, and mechanical assemblies. It is suited for licensed tradespeople and experienced service technicians who need a reliable hand tool for routine fastener work on residential and light commercial equipment. The compact overall length makes it practical in confined spaces such as air handler cabinets, electrical enclosures, and mechanical rooms.

Installation Notes

Always ensure the wrench is fully seated on the fastener before applying torque to avoid rounding. Keep the tool clean and inspect for cracks or deformation before use in high-torque applications. No special installation is required; standard hand-tool safety practices apply.
