2-3/16" 12-Point SAE SUPERCOMBO® Combination Wrench - J.H. Williams

The J.H. Williams JHW1193 2-3/16" 12-Point SAE SUPERCOMBO® Combination Wrench is engineered for demanding professional applications in automotive and industrial settings. This heavy-duty wrench combines innovative design features to provide superior fastener engagement and prevent rounding, making it an essential tool for rigorous maintenance and assembly tasks. Its robust construction ensures reliability and extended service life in challenging working environments.

Key Features

• SuperCombo® Open End Design: Features specially engineered grooves that strategically direct wrench force away from fastener corners, significantly reducing the risk of rounding and damage during high-torque applications.
• SuperTorque™ Box Opening: This advanced 12-point design allows for the application of higher torque without deforming hex fastener points. Wrenching forces are precisely placed on the flat surfaces behind the points, avoiding contact with the corners.
• Aerospace Specification Compliance: Meets or exceeds aerospace specification AS 954 for 12-point fasteners (as defined by AS 870), ensuring a precise torque/tension relationship for critical and precision applications.
• Versatile Fastener Engagement: While optimized for 12-point fasteners, the SuperTorque™ box end offers considerable advantages over conventional box end wrenches when used on all common hex (6-point) fasteners, enhancing overall tool flexibility and economy.
• Identical Opening Sizes: Both the open end and box end openings are precisely machined to the same 2-3/16" size, ensuring consistent fit and reliable function across various tasks.

Applications

This 2-3/16" combination wrench is an invaluable tool for professional technicians and mechanics engaged in heavy-duty maintenance across various sectors. It is ideally suited for securing or removing substantial fasteners found in large-scale automotive components, truck and bus maintenance, agricultural machinery, and construction equipment. Its robust design makes it particularly effective for industrial machinery and MRO (Maintenance, Repair, and Operations) tasks where high torque is frequently applied and fastener integrity is paramount. This wrench is built for repetitive, high-stress use in professional shop and field environments.
