Socket 1/2" 16 mm (6-point) JCB JCB-54516

1/2" drive 16 mm 6-point socket by JCB, model JCB-54516, is a medium-size workshop tool designed for use with 1/2-inch drive ratchets and torque tools. The socket features a 6-point internal profile to provide secure engagement with hex fasteners, reducing the risk of rounding bolt heads and enabling controlled torque application. Its size and drive compatibility make it suitable for a wide range of automotive, mechanical maintenance and general workshop tasks where reliable medium-sized sockets are required.

Advantages

The 6-point internal geometry concentrates contact on the flats of fasteners, improving grip under high torque and lowering the chance of slipping or damage. A 1/2" drive interface ensures compatibility with common ratchets and torque wrenches used in professional and hobbyist settings. Constructed to fit standard 16 mm hex fasteners, the socket balances accessibility in confined spaces with the strength needed for automotive and mechanical applications.

Suitable for

• Automotive repair and maintenance (engine, suspension, brake components)
• Mechanical assembly and disassembly of machinery
• Workshop and garage general maintenance tasks
• Use with 1/2" drive ratchets and torque wrenches for controlled tightening

Key specifications

• Drive size: 1/2" (12.7 mm) compatible with 1/2-inch tools
• Socket size: 16 mm internal hex
• Internal profile: 6-point (hex)
• Intended use: hand tools and torque tools for medium-size fasteners
• Typical applications: automotive, mechanical maintenance, general workshop tasks

How to use

Select the socket that matches the fastener size and attach it securely to a 1/2" drive ratchet or torque wrench. Place the socket over the fastener, ensuring full seating on the flats, and apply torque in the required direction. For loosening, apply steady counter-clockwise torque; for tightening, apply clockwise torque while observing any specified torque settings if using a torque wrench. Inspect the socket and fastener for proper fit before use to avoid slippage.

Usage recommendations

Use the socket with the correct 1/2" drive tools and avoid excessive force beyond recommended torque values for the fastener. Keep the socket clean and free of debris; inspect for wear or distortion before each use. When working in confined or rusted conditions, consider using penetrating fluid and a steady, controlled motion to reduce the risk of fastener or tool damage.
