15 pc SAE SUPERCOMBO® Combination Wrench Set - J.H. Williams

Specifications

The J.H. Williams 15 pc SAE SUPERCOMBO® Combination Wrench Set, model JHWWS1172SCA, offers a comprehensive range of standard (SAE) sizes for various fastening tasks. This set includes 15 wrenches, covering sizes from 5/16 inch to 1 1/4 inch. Each wrench is crafted from special alloy steel, undergoing precision forging and heat-treatment to ensure optimal strength and long-term durability. The set features a polished chrome finish, providing both a professional appearance and resistance to corrosion. Manufactured in the USA, this combination wrench set weighs approximately 14.54 lbs.

Key Features

• SUPERCOMBO® Open End Design: The open end features specially engineered grooves that strategically direct wrench force away from the fastener corners. This design minimizes the risk of rounding or damaging fasteners during use.
• SUPERTORQUE® Box Opening: The 12-point box end is engineered to allow for the application of higher torque without deforming hex fastener points. Force is applied to the flat surfaces behind the points, not directly on the corners, ensuring a secure grip and preventing slippage.
• Aerospace Standard Compliance: This wrench set meets or exceeds aerospace specification AS 954 for 12-point fasteners, providing an accurate torque/tension relationship for precision applications. It can also be effectively used on common 6-point hex fasteners.
• Identical Open and Box End Openings: Both the open and box ends feature identical openings, providing consistent fit and performance.
• Ergonomic Design: Each wrench is designed with a longer handle for improved comfort, balance, and increased leverage, particularly in confined spaces. The thin profile of the wrenches enhances accessibility in tight clearances.

Applications

The J.H. Williams 15 pc SAE SUPERCOMBO® Combination Wrench Set is an essential tool for a wide array of tasks requiring the tightening or loosening of SAE fasteners.
