1/4" 12-Point SAE SUPERCOMBO® Combination Wrench - J.H. Williams

The J.H. Williams JHW1208SC 1/4" 12-Point SAE SUPERCOMBO® Combination Wrench is engineered for professional technicians and mechanics requiring reliable performance and enhanced fastener protection. This versatile tool combines the benefits of an open-end and box-end wrench, designed to deliver higher torque capabilities while minimizing the risk of fastener damage in demanding automotive and industrial applications.

Key Features

• SUPERCOMBO® Open End Design: Features specially designed grooves that strategically direct wrench force away from the corners of the fastener. This innovative design helps prevent rounding and deforming of fastener points, extending the life of both the fastener and the tool.
• SUPERCOMBO® SuperTorque™ Box Opening: The 12-point box end utilizes a SuperTorque™ design that applies wrenching forces to the flat surfaces behind the points of the fastener, not directly on the corners. This allows for the application of significantly higher torque without rounding or deforming hex fastener points.
• 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 in critical environments.
• Versatile Fastener Engagement: While optimized for 12-point fasteners, the advanced design offers considerable advantages over conventional box-end wrenches when used on common hex (6-point) fasteners, enhancing both hand tool flexibility and economy for professionals.
• Professional-Grade Construction: Built by J.H. Williams, this wrench is constructed for durability and long-term performance in rigorous shop and industrial settings, providing a dependable tool for daily professional use.
