Socket bit 3/4" 30 mm (6-point) – JCB

JCB 3/4" 30 mm 6-point socket bit designed for impact use. This six-point socket fits 3/4-inch drives and engages fasteners securely to reduce rounding and slippage during heavy torque operations. Intended for use with impact wrenches and rattle guns, the socket is suitable for mechanics, technicians and maintenance professionals working on automotive, construction and industrial equipment where durable, high-torque connections are required.

Advantages

The six-point geometry ensures a firm grip on hexagonal fasteners, minimizing the chance of rounding and enabling efficient torque transfer. Constructed for impact applications, the socket tolerates repeated high-torque cycles when used with compatible impact tools. Its 30 mm size covers a common fastener dimension in automotive and machinery maintenance, offering a balance between reach and strength for heavy-duty work.

Suitable for

• Automotive wheel and suspension maintenance
• Construction equipment repairs
• Industrial and factory maintenance
• Heavy machinery assembly and disassembly

Key specifications

• Drive size: 3/4 inch
• Socket size: 30 mm
• Point configuration: 6-point (hexagonal)
• Intended use: impact-rated for use with impact wrenches and rattle guns
• Typical applications: high-torque fastening and loosening on heavy-duty equipment

How to use

Select a 3/4" drive impact wrench or adapter and fit the 30 mm 6-point socket onto the drive. Position the socket squarely over the fastener to ensure full contact with all six points before applying torque. When loosening, apply short bursts of impact and use controlled directional settings on the tool. When tightening, apply torque in accordance with manufacturer specifications for the fastener to avoid over-tightening, and verify final torque with a calibrated torque wrench if required.

Usage recommendations

Use only with impact-rated 3/4" drive tools and avoid combining with non-impact ratchets or extensions that are not rated for impact service. Inspect the socket regularly for wear, cracking or rounding and replace if damage is detected. For precise torque requirements, finish with a calibrated torque wrench rather than relying solely on an impact tool.
