Williams JHW1227MSC Combination Wrench 27 Mm 12-point

Product Description

The WILLIAMS COMFORT PRODUCTS JHW1227MSC is a 27 MM combination wrench built for high-torque fastener work in trade and industrial settings. It features a 12-point SUPERTORQUE box end and a SUPERCOMBO open end, both engineered to maximize grip on hex fasteners while reducing the risk of rounding or deforming fastener points. The box end transfers wrenching force to the flat surfaces behind the fastener points rather than the corners, allowing higher torque application than conventional box end wrenches. A high-polish chrome finish resists corrosion in demanding shop and field environments. This wrench meets ANSI B107.6 and SAE AS 954 specifications.

The JHW1227MSC suits mechanical, HVAC, plumbing, and electrical trade work wherever metric hex fasteners are encountered. The 27 MM opening fits common metric bolt and nut sizes used on equipment mounts, flanges, valve bodies, and mechanical assemblies. The SUPERCOMBO open end design uses specially shaped grooves to redirect force away from fastener corners, making it useful on both standard and partially worn fasteners. It is appropriate for residential, commercial, and light industrial service work.

Key Features

• 27 MM opening fits common metric hex fasteners
• 12-point SUPERTORQUE box end applies force to fastener flats, not corners, reducing rounding risk
• SUPERCOMBO open end with engineered grooves directs force away from fastener corners
• Compatible with all common 6-point hex fasteners with performance advantage over standard box end wrenches
• High-polish chrome finish for corrosion resistance and durability
• Meets ANSI B107.6 and SAE AS 954 federal specifications

Compatibility

Designed for use on standard metric hex fasteners; suitable as a general-purpose combination wrench for trade and mechanical service applications.

Installation Notes

Confirm the wrench opening matches the fastener size before applying torque. Power down or de-energize equipment and relieve system pressure before servicing fastened connections on live mechanical or fluid systems. Use the box end for final tightening and break-loose tasks where higher torque is needed, and the open end for faster spinning in accessible locations. Follow applicable trade codes and equipment manufacturer torque guidance when specified.
