Socket 1/2" 27 mm (6-point) JCB

1/2" 27 mm 6-point socket by JCB is a compact metal tool designed for use with 1/2-inch drive ratchets and torque wrenches. It fits 27 mm hexagonal fasteners and is intended for turning bolts and nuts in automotive, mechanical and general maintenance tasks. The six-point design distributes torque across flat faces of fasteners to reduce rounding and improve grip during high-torque operations.

Advantages

The 6-point geometry ensures secure engagement with hex fasteners and reduces the chance of slipping under load. Constructed from durable alloy steel with precision-machined internal profiles, the socket offers consistent fit and long service life. Its standard 1/2" drive interface makes it compatible with common ratchets, extensions and torque wrenches used in workshops and garages. The compact length allows access to fasteners in confined spaces while maintaining required strength for demanding tasks.

Suitable for

• Automotive repair and maintenance
• Mechanical assembly and disassembly
• Workshop and garage tool sets
• General industrial and home maintenance

Key specifications

• Drive size: 1/2 inch
• Material: alloy steel (hardened and machined)
• Finish: corrosion-resistant coating
• Compatible with: ratchets, torque wrenches and extensions with 1/2" drive
• Design: compact length for access in tight spaces

How to use

Select the 27 mm socket for a matching hexagonal fastener, attach it securely to a 1/2" drive ratchet, extension or torque wrench, then engage the socket fully onto the fastener before applying torque. When using a torque wrench, set the required torque value and turn smoothly until the wrench indicates the set value. For removal, reverse the ratchet direction and apply steady force to avoid stripping the fastener.

Usage recommendations

Inspect the socket for wear or damage before each use, and avoid using with impact tools unless the socket is specifically rated for impact service. Use appropriate personal protective equipment when working with high torque. Store the socket in a dry toolbox or socket rail to prevent corrosion and maintain fit accuracy.
