1-1/2" 12-Point SAE SUPERCOMBO® Combination Wrench - J.H. Williams

The J.H. Williams JHW1248 1-1/2" 12-Point SAE SUPERCOMBO® Combination Wrench is engineered for demanding professional applications, providing enhanced grip and torque capabilities. This robust tool combines an innovative open end with a high-performance box end, designed to protect fasteners while delivering superior power transfer in automotive and industrial settings.

Key Features

• Advanced Fastener Engagement: The SUPERCOMBO® open end features specially designed grooves that distribute wrenching force away from fastener corners, significantly reducing the risk of rounding and damage during high-stress applications.
• Superior Torque Application: Equipped with the SuperTorque™ box opening design, this wrench allows technicians to apply higher torque without deforming or rounding hex fastener points. Forces are precisely directed to the flat surfaces behind the points, rather than directly on the corners.
• Aerospace Standard Compliance: Meets or exceeds aerospace specification AS 954 for 12-point fasteners (as defined by AS 870), ensuring an accurate torque-to-tension relationship critical for precision assembly and maintenance.
• Versatile Performance: While optimized for 12-point fasteners, its innovative design provides considerable advantages over conventional box end wrenches when used on common hex (6-point) fasteners, enhancing tool flexibility.
• Identical Opening Sizes: Both the box and open end openings are precisely machined to 1-1/2" SAE, offering consistent fit and function across both ends of the wrench.

Applications

This J.H. Williams SUPERCOMBO® Combination Wrench is an essential tool for professional technicians and mechanics working on heavy-duty machinery, industrial equipment, and challenging automotive repairs. It is particularly valuable in situations requiring the application of significant torque on stubborn fasteners, where the prevention of fastener rounding is paramount. Its precision and durability make it suitable for tasks in manufacturing, maintenance, and vehicle service bays where reliability and efficiency are critical.
