Socket 1/2" 20 mm (6-point) JCB

JCB 1/2" 20 mm 6-point socket is a hand tool designed for fastening and loosening nuts and bolts with a 20 mm head. Built to fit a 1/2-inch drive, the socket offers a six-point internal profile that ensures positive engagement with hex fasteners and helps reduce rounding under load. The tool is suitable for workshop and field use where reliable torque transfer and compatibility with common ratchets and extension bars are required.

Advantages

The 6-point profile provides firm contact with flat sides of hex heads, minimizing slippage and fastener damage. Compatibility with a 1/2-inch drive allows the socket to be used with a wide range of ratchets, torque wrenches and extensions. Robust construction and precision machining support consistent torque application and long service life in regular repair and maintenance tasks.

Suitable for

• Automotive repair and wheel and chassis maintenance
• Industrial equipment servicing and assembly
• General mechanical repairs in workshops and on-site jobs

Key specifications

• Drive size: 1/2 inch
• Socket size: 20 mm
• Point configuration: 6-point (hex)
• Material: high-strength tool steel (heat-treated)
• Finish: corrosion-resistant coating or plating for durability
• Connection type: square recess to accept 1/2-inch drive accessories

How to use

Select the 20 mm socket and attach it securely to a compatible 1/2-inch drive ratchet, breaker bar or torque wrench. Position the socket squarely over the fastener head to ensure full six-point contact, then apply steady turning force in the required direction. For removal of stubborn fasteners, use a breaker bar or apply penetrating lubricant as needed. When using a torque wrench, observe the specified torque values for the fastener and avoid exceeding tool limits.

Usage recommendations

Use the socket with appropriate 1/2-inch drive accessories and avoid applying impact tools unless the socket is rated for impact use. Keep the socket clean and lightly lubricated to prevent corrosion, and inspect regularly for wear or rounding of the internal profile. Store in a socket rail or organizer to maintain condition and ensure quick selection during maintenance tasks.
