Socket 1/2" 8mm (6-point) by JCB, model JCB-54508

This 1/2" 8mm 6-point socket by JCB is engineered for use with standard 1/2-inch drive ratchets and handles. It fits 8 mm hex fasteners with a six-point profile to reduce rounding and provide secure engagement when applying torque. The socket is intended for mechanical, automotive, and general maintenance work where a reliable connection between drive tool and fastener is required.

Advantages

The six-point geometry concentrates force on the flats of fasteners to minimize slippage and damage. Designed for 1/2" drive systems, the socket offers compatibility with a wide range of ratchets, breaker bars and extension bars. Its precise 8 mm sizing ensures accurate fit on metric hex bolts and nuts, supporting consistent torque transfer during tightening and loosening operations.

Suitable for

• Automotive repair and servicing tasks involving 8 mm hex fasteners
• Mechanical assembly and disassembly of machinery with metric bolts
• Routine maintenance and workshop tool sets using 1/2" drive tools

Key specifications

• Drive size: 1/2 inch
• Socket size: 8 mm
• Point profile: 6-point (hex)
• Intended use: hand-operated drive tools (ratchets, handles, breaker bars)
• Compatibility: standard 1/2" drive toolsets and extensions

How to use

Select the socket and attach it securely to a compatible 1/2" drive ratchet, extension, or breaker bar. Place the socket squarely over the 8 mm hex fastener, ensuring full engagement with the six-point profile before applying force. Turn the ratchet or handle in the required direction to tighten or loosen the fastener, applying steady, controlled torque to avoid stripping or rounding the bolt head.

Usage recommendations

Inspect the socket and fastener for wear or damage before use. For high-torque applications, use appropriate extensions or a breaker bar and avoid excessive impact on hand-operated sockets. Store the socket in a clean, dry tool case to prevent corrosion and maintain fit accuracy.
