The J.H. Williams JHW1198B 2-7/8" 12-Point SAE SUPERCOMBO® Combination Wrench is engineered for demanding professional environments, delivering superior grip and torque capabilities. Its innovative design protects fasteners while enabling technicians to apply substantial force without fear of rounding or deforming hex points. This wrench is a reliable addition to any professional automotive or industrial toolkit, offering precision and durability.

Key Features

• SUPERCOMBO® Open End Design: Features specially designed grooves that redirect wrench force away from fastener corners, minimizing damage and maximizing contact area.
• SuperTorque™ Box Opening: Engineered to apply wrenching forces directly on the flat surfaces behind fastener points, allowing for higher torque application without rounding or deforming hex fasteners.
• Aerospace Specification Compliance: Meets or exceeds aerospace specification AS 954 for 12-point fasteners (as defined by AS 870), ensuring an accurate torque/tension relationship for precision applications.
• Versatile Fastener Compatibility: While designed for 12-point fasteners, the SuperTorque™ box end offers significant advantages over conventional wrenches when used on common hex (6-point) fasteners, improving flexibility and efficiency.
• Professional-Grade Construction: Built by J.H. Williams, known for high-quality professional automotive and industrial tools, ensuring durability and long service life.
• Identical Opening Sizes: Both the box and open end openings are precisely the same size, providing consistent fit and application.

Applications

This J.H. Williams SUPERCOMBO® combination wrench is ideally suited for a wide range of professional tasks in automotive repair shops, heavy machinery maintenance, and industrial settings. Its ability to apply high torque safely makes it invaluable for working on stubborn or tightly secured fasteners found in engines, transmissions, chassis components, and industrial equipment. Technicians will find it particularly useful in situations requiring precise torque application, where fastener integrity is critical, or when dealing with both 6-point and 12-point SAE hex fasteners.
