7/8" 12-Point SAE SUPERCOMBO® Combination Wrench - J.H. Williams

The J.H. Williams JHW1228SC 7/8" 12-Point SAE SUPERCOMBO® Combination Wrench is engineered for professional technicians and mechanics seeking reliable, high-performance fastening tools. Manufactured in the USA, this precision wrench is designed to deliver superior torque and protect fasteners from damage, making it an essential addition to any professional toolkit for automotive or industrial applications.

Key Features

• Advanced Open End Design: The SUPERCOMBO® open end features specially designed grooves that effectively direct wrenching force away from the corners of fasteners, significantly reducing the risk of rounding and damage.
• High-Torque Box End: Equipped with the SUPERTORQUE™ box opening, this wrench allows for the application of higher torque without deforming or rounding hex fastener points. Forces are strategically placed on the flat surfaces behind the points, ensuring secure engagement.
• Aerospace and Industrial Grade Compliance: Meets or exceeds aerospace specification AS 954 for 12-point fasteners (as defined by AS 870) and ANSI B107.6, ensuring accurate torque/tension relationships for precision applications.
• Versatile Fastener Compatibility: While optimized for 12-point fasteners, its design provides a considerable advantage over conventional box end wrenches when used on common hex (6-point) fasteners, enhancing both tool flexibility and economy.
• Durable Construction: Crafted with a satin chrome finish, this J.H. Williams wrench is built for demanding professional environments, offering corrosion resistance, easy cleaning, and long-lasting performance. It is also backed by a Limited Lifetime Warranty.
