Socket 1/2" 30mm 6-point JCB (model JCB-54530)

Socket 1/2" 30mm 6-point JCB (model JCB-54530) is a 1/2-inch drive 30 mm 6-point socket designed for tightening and loosening bolts and nuts in automotive, industrial maintenance and general mechanical tasks. The 6-point geometry ensures contact on flat sides of fasteners to reduce rounding and improve torque transfer, while the 1/2" drive compatibility allows use with standard ratchets, breaker bars and torque wrenches.

Advantages

This JCB 6-point socket provides secure engagement with 30 mm hex fasteners to minimize slipping and rounding. Constructed to work with 1/2" drive tools, it delivers reliable torque transfer for demanding applications. The 6-point design concentrates force on the flats of fasteners, improving grip on worn or high-torque bolts compared with 12-point alternatives. The socket's dimensional fit and drive interface make it suitable for use with various hand and power tool accessories.

Suitable for

• Automotive repair and maintenance — wheel nuts, engine and suspension fasteners
• Industrial maintenance — machinery assembly and disassembly
• General mechanical work — construction, fabrication and on-site repairs
• Use with 1/2" drive ratchets, breaker bars and torque wrenches

Key specifications

• Drive size: 1/2 inch
• Socket size: 30 mm
• Point configuration: 6-point (hex)
• Intended fastener type: hexagonal bolts and nuts
• Compatibility: standard 1/2" drive tool accessories (ratchets, torque wrenches, breaker bars)
• Typical applications: automotive, industrial and mechanical maintenance

How to use

Select the 30 mm 6-point JCB socket for the corresponding hex fastener and attach it securely to a 1/2" drive ratchet, breaker bar or torque wrench. Position the socket squarely on the fastener flats to ensure full contact with the 6-point profile. Apply torque evenly, avoiding sudden impacts that exceed tool or fastener ratings. For removal of tight or corroded fasteners, use controlled force and appropriate penetrating lubricant or heat where safe and required.

Usage recommendations

Inspect the socket and drive tool before use for wear or damage. Use the 6-point socket when high torque and reduced rounding risk are priorities. When applying specified torque values, use a calibrated torque wrench to avoid over-tightening. Store the socket in a dry tool chest or rack to prevent corrosion and maintain dimensional accuracy.
