6 pc SAE SUPERCOMBO® Combination Wrench Set - J.H. Williams

The J.H. Williams JHWWS-1175 6 pc SAE SUPERCOMBO® Combination Wrench Set is designed for professional technicians and mechanics who service heavy equipment, Class 6–8 trucks, and industrial machinery. This set delivers reliable fastener engagement and high torque transfer for large SAE fasteners in demanding service environments, contributing to operational efficiency and extended fastener life.

Key Features

• Large SAE Size Coverage: This 6-piece set includes combination wrenches in sizes 2-1/16", 2-1/8", 2-3/16", 2-1/4", 2-3/8", and 2-1/2". These sizes are essential for addressing common requirements on bushings, suspension components, flanges, and other large hardware.
• SUPERCOMBO® Open End Design: The innovative open end is engineered to drive on the flats of the fastener rather than the corners. This design minimizes the risk of rounding, directs load away from fastener edges, and helps extend fastener longevity.
• SUPERTORQUE® 12-Point Box End: The box opening applies torque to the flats behind the points of the fastener, enabling higher torque transfer on both 12-point and 6-point fasteners without deforming hex corners.
• Aerospace-Grade Accuracy: Designed to meet or exceed aerospace specifications AS 954 for 12-point fasteners (as defined by AS 870), this set supports critical applications where precise torque and tension relationships are paramount.
• Professional-Grade Construction: Each wrench is crafted from special alloy steel, precision-forged, and heat-treated to ensure superior strength and durability. A polished chrome finish provides corrosion resistance and simplifies cleaning.
• Made in USA: Manufactured in the USA, this set adheres to stringent quality control standards, ensuring reliability for demanding shop and field environments.

Applications

• Service and maintenance for Class 6–8 trucks, buses, and commercial vehicles.
• Maintenance of heavy equipment and off-highway machinery.
• Installation, alignment, and repair of industrial machinery.
• Construction, structural steel, and plant MRO (Maintenance, Repair, and Operations) work involving large SAE fasteners.
