5/8" 12-Point SAE SUPERCOMBO® High Visibility Yellow Combination - J.H. Williams

The J.H. Williams JHW1220YSC 5/8" 12-Point SAE SUPERCOMBO® High Visibility Yellow Combination Wrench is engineered for demanding professional applications. This robust tool combines innovative open and box end designs to deliver superior grip, prevent fastener damage, and ensure reliable performance in both automotive and industrial environments. It provides technicians with enhanced leverage and reduced risk of fastener wear across various tasks.

Key Features

• SuperCombo® Open End Design: Features specially designed grooves that direct wrenching force away from fastener corners, significantly reducing the risk of rounding while improving grip on hex fasteners.
• SuperTorque™ Box Opening: Engineered to apply force on the flat surfaces behind hex fastener points, enabling the application of higher torque without rounding or deforming the fastener. This design meets or exceeds aerospace specification AS 954 for 12-point fasteners (as defined by AS 870), ensuring precise torque/tension relationships.
• Versatile Fastener Compatibility: While optimized for 12-point fasteners, the SuperTorque™ box end offers considerable advantages over conventional box end wrenches when used on all common 6-point hex fasteners, increasing hand tool flexibility and economy.
• High Visibility Yellow Finish: The bright yellow coating improves tool identification in cluttered workspaces and helps prevent loss, contributing to better organization and efficiency.
• Professional-Grade Construction: Built from high-quality materials to withstand the rigorous demands of daily professional use, ensuring long-lasting durability and reliability in challenging automotive and industrial settings.
