1/2" Drive 6-Point Metric 20 mm Shallow Impact Socket - J.H. Williams

The J.H. Williams JHW4M-620 1/2" Drive 6-Point Metric 20 mm Shallow Impact Socket is a professional-grade tool engineered for the demanding conditions of automotive and industrial service. Manufactured in the USA from impact-grade chrome molybdenum steel, this socket provides reliable performance in high-torque applications where standard chrome sockets may falter. Its shallow profile offers essential clearance in restricted areas without compromising strength or fastener engagement, making it a critical tool for any professional.

Key Features

• 1/2" Drive Impact-Ready Design: Engineered for seamless compatibility with standard 1/2" drive pneumatic and cordless impact wrenches, ensuring efficient use with common shop tools for passenger cars, light trucks, and commercial vehicles.
• 6-Point SUPERTORQUE® Lobular Opening: The precision-machined lobular design securely grips the flats of fasteners, significantly minimizing the risk of rounding, particularly on corroded or damaged nuts and bolts.
• Shallow Profile: The 20 mm shallow impact socket configuration offers improved access and maneuverability in tight areas such as suspension components, engine bays, and chassis clearances.
• Chrome Molybdenum Steel Construction: Constructed from specially heat-treated chrome molybdenum steel, this professional-grade impact socket is built to withstand repeated impact cycles and heavy shop use, ensuring long-term durability. Chrome molybdenum steel is known for its toughness and ability to absorb shock without cracking, unlike more brittle chrome vanadium steels.
• Corrosion-Resistant Black Industrial Finish: A durable black finish provides enhanced corrosion resistance and ensures size markings remain highly visible for quick identification and organization.
