1/4" Drive 6-Point SAE 9/16" Deep Socket - J.H. Williams

The J.H. Williams JHWMD-618, also known as the STX618, is a professional-grade 1/4" Drive 6-Point SAE 9/16" Deep Socket designed for technicians and mechanics requiring reliable access to deeply recessed 9/16" fasteners. This deep well socket provides precise fitment and efficient torque transfer, making it an essential tool for demanding automotive and industrial service applications where space is limited.

Key Features

• Optimal Access: The 1/4" drive and 9/16" SAE size offer critical access for common fasteners in tight spaces, allowing technicians to work efficiently where larger drive sizes are impractical.
• Secure 6-Point SUPERTORQUE® Design: Features SUPERTORQUE® lobular openings, engineered for maximum engagement on 6-point fasteners. This design minimizes the risk of rounding and slippage, even on stubborn or worn hardware.
• Deep Well Profile: Specifically designed to clear long studs and reach deeply set nuts in confined engine bays, mounting assemblies, and other difficult locations.
• Professional-Grade Construction: Manufactured by J.H. Williams, a brand recognized for producing high-quality drop-forged tools, ensuring superior strength, lasting durability, and a consistent fit for demanding daily shop use.
• Versatile Compatibility: Fully compatible with any standard 1/4" drive ratchet, torque wrench, extension, or flex handle for broad utility across various tasks.

Applications

This deep socket is essential for a range of automotive and light truck repair work, particularly where 9/16" fasteners are found on brackets, clamps, small suspension hardware, and accessory mounts. It excels in engine bay service, under-dash repairs, and tight undercarriage locations where a 3/8" drive setup would be too bulky. Beyond vehicles, it is well-suited for machinery maintenance, equipment assembly, and industrial repair tasks involving recessed 9/16" SAE nuts and bolts on extended threads or in confined spaces.
