Williams JHW1217MRS 17MM 12-point Ratcheting Combination Wrench

Product Description

The WILLIAMS COMFORT PRODUCTS JHW1217MRS is a 17 MM combination wrench built for trade professionals who need reliable torque transfer and a compact swing arc in confined workspaces. The box end uses a 12-point SUPERTORQUE profile that contacts the flat surfaces of a hex fastener rather than the corners, reducing the risk of rounding or deforming fastener points under high torque. The open end features a SUPERCOMBO profile with machined grooves that redirect wrenching force away from fastener corners. The ratcheting gear mechanism includes up to 80 teeth, allowing shorter arc movement between strokes.

This wrench suits HVAC, plumbing, electrical, and general mechanical applications where technicians work around equipment frames, pipe hangers, mounting hardware, and structural fasteners. The longer handle geometry is sized for improved leverage and balance, making it practical in both open and restricted access areas. It is sold individually and fits 17 MM hex fasteners in both residential and light commercial service environments.

Key Features

• SUPERTORQUE 12-point box opening contacts flat fastener surfaces, not corners, allowing higher torque without deforming fastener points
• SUPERCOMBO open end with grooved profile directs force away from fastener corners
• Up to 80 ratcheting teeth minimize the required swing arc in tight spaces
• Forged from special alloy steel and heat treated for strength and durability
• Extended handle length provides increased leverage and balanced grip

Compatibility

Designed for use with 17 MM hex fasteners in standard combination wrench applications across HVAC, plumbing, and mechanical service work.
