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

The J.H. Williams JHWWS-1175 6 pc SAE SUPERCOMBO® Combination Wrench Set is engineered for professional technicians and mechanics maintaining heavy equipment, Class 6–8 trucks, and industrial machinery. This set provides reliable engagement and high torque transfer for large SAE fasteners in demanding service environments, ensuring efficiency and fastener longevity.

Key Features

• Large SAE Size Coverage: This set includes 2-1/16", 2-1/8", 2-3/16", 2-1/4", 2-3/8", and 2-1/2" combination wrenches, addressing common requirements for bushings, suspension components, flanges, and large hardware.
• SUPERCOMBO® Open End Design: The open end drives on the flats of the fastener, not the corners, which minimizes rounding and extends the life of fasteners by directing load away from their edges.
• SUPERTORQUE® 12-Point Box End: The box opening applies torque to the flats behind the points, facilitating higher torque transfer on both 12-point and 6-point fasteners without deforming hex corners.
• Aerospace-Grade Accuracy: Designed to meet or exceed AS 954 for 12-point fasteners (AS 870), supporting critical applications where consistent torque and tension relationships are essential.
• Professional-Grade Construction: Crafted from special alloy steel, each wrench is precision-forged and heat-treated for superior strength and durability, with a polished chrome finish for corrosion resistance and easier cleaning.
• Made in USA: Domestic manufacturing ensures adherence to stringent quality control standards, providing reliability for demanding shop and field environments.

Applications

• Class 6–8 truck, bus, and commercial vehicle service
• Heavy equipment and off-highway machinery maintenance
• Industrial machinery installation, alignment, and repair
• Construction, structural steel, and plant MRO work involving large SAE fasteners
