This J.H. Williams 11-piece SAE SUPERCOMBO® Combination Wrench Set (JHWWS1171BSC) is engineered for professional technicians and mechanics who require precision, durability, and superior fastener protection in automotive and industrial environments. Featuring advanced SuperCombo® and SuperTorque™ designs, this set is built to handle high-torque applications without damaging fasteners, ensuring reliable performance on the job. The robust black industrial finish provides enhanced corrosion resistance and long-lasting tool life.

Key Features:

• Comprehensive SAE Set: Includes 11 wrenches in essential SAE sizes: 3/8", 7/16", 1/2", 9/16", 5/8", 11/16", 3/4", 13/16", 7/8", 15/16", and 1".
• SuperCombo® Open End Design: Specially designed grooves direct wrench force away from fastener corners, significantly reducing the risk of rounding or deforming hex fasteners.
• SuperTorque™ Box Opening: This innovative 12-point box end design applies wrenching forces to the flat surfaces behind the points, allowing for higher torque application without stripping or damaging hex and 12-point fasteners.
• Aerospace Grade Compliance: Meets or exceeds aerospace specification AS 954 for 12-point fasteners (as defined by AS 870), ensuring accurate torque/tension relationships for precision applications.
• Durable Industrial Finish: A black industrial finish provides excellent resistance to corrosion and wear, extending the lifespan of the tools in demanding work conditions.
• Identical Open and Box End Openings: Both the open and box end openings are precision-machined to identical sizes for consistent fit and performance across all fasteners.

Applications:

This professional-grade wrench set is ideal for a wide range of tasks, including general automotive repair and maintenance, heavy equipment service, machinery assembly, and industrial maintenance. Its superior fastener engagement technologies make it particularly effective for working with critical fasteners where preventing rounding and applying precise torque are paramount. It offers considerable advantages over conventional wrenches on both common 6-point hex and specialized 12-point fasteners.
