Socket wrench 3/4" 27mm 6-point — JCB (JCB-46527)

Impact socket 3/4" drive, 27 mm, 6-point by JCB is a durable tool intended for heavy-duty torque applications. Designed to be used with air or electric impact wrenches, this 27 mm 6-point socket offers precise engagement with hex fasteners to help minimise rounding and slipping under high torque. The socket's size and drive type make it appropriate for larger nuts and bolts commonly found in automotive, agricultural and industrial equipment maintenance.

Advantages

This 6-point impact socket provides a tight fit on hex heads, improving torque transfer and reducing the risk of fastener damage. Constructed to withstand repeated impact loads, the socket is suitable for high-torque environments and frequent professional use. Its 3/4" drive ensures compatibility with standard heavy-duty impact tools, while the 27 mm opening matches common metric fasteners used in machinery and vehicle assemblies.

Suitable for

• Removing and installing wheel nuts and large fasteners on commercial and passenger vehicles
• Maintenance and repair of agricultural machinery and implements
• Industrial assembly and disassembly tasks requiring high torque
• Workshop use with pneumatic or electric impact wrenches

Key specifications

• Drive size: 3/4"
• Socket size: 27 mm
• Point configuration: 6-point (hex)
• Intended use: impact applications
• Typical compatibility: air and electric impact wrenches

How to use

Select the 27 mm 6-point socket and attach it securely to a compatible 3/4" drive impact wrench. Position the socket squarely on the fastener and apply controlled bursts of torque rather than continuous maximum power to prevent fastener damage. When removing fasteners that have been exposed to corrosion or heavy load, begin with a lower torque setting and increase as needed. After use, inspect the socket for wear or cracks and store it in a dry toolbox or socket rail.

Usage recommendations

Use with a matched-quality impact wrench and avoid using the socket with hand ratchets or cheater bars for high-torque jobs. Regularly check the socket for deformation or rounding; replace if any damage is detected to maintain safe and reliable performance.
