Socket 1/2" 20 mm (6-point) JCB - hex impact socket for 1/2-inch drive

Impact socket by JCB, 20 mm size for 1/2" drive, 6-point (hex) design manufactured for use with impact wrenches and torque tools. This hex impact socket fits 20 mm hex fasteners and is engineered to transfer high torque while minimising rounding of bolt heads. The component is intended for demanding mechanical environments such as automotive repair, heavy machinery maintenance and industrial assembly where impact-rated tools are required.

Advantages

The 6-point geometry concentrates contact on the flats of fasteners to reduce slippage and preserve fastener integrity. Designed for a 1/2" drive, the socket accepts common torque and impact tools and delivers reliable power transfer. Its construction and heat-treated steel composition provide increased durability under repeated impact load, while the internal profile reduces the risk of rounding and damage to fasteners. The socket’s size and profile make it compatible with a wide range of workshop and field applications.

Suitable for

• Automotive maintenance and engine work requiring high-torque fastening and removal
• Heavy equipment and agricultural machinery repair
• Industrial assembly lines where impact tools are used
• Field service and mobile workshops that use impact wrenches

Key specifications

• Drive size: 1/2 inch
• Socket nominal size: 20 mm
• Point configuration: 6-point (hex)
• Intended use: impact-rated for use with impact wrenches and torque tools
• Material: heat-treated steel suitable for impact applications

How to use

Select the 20 mm 6-point socket for the matching hex fastener and mount it securely on a 1/2" drive impact wrench or ratchet with impact capability. Ensure the socket fully engages the fastener flats before applying torque. When removing fasteners, use controlled pulses rather than continuous maximum power to avoid fastener or tool damage. Inspect the socket and fastener condition regularly and replace the socket if visible cracking, deformation or excessive wear appear.

Usage recommendations

Use appropriate personal protective equipment and follow the impact tool manufacturer's torque and safety guidelines. Store the socket in a dry, organized toolbox or socket rail to prevent corrosion and mechanical damage when not in use.
