Socket bit 3/4" 30 mm (6-point) JCB

JCB 3/4" 30 mm 6-point socket bit designed for impact use. This socket bit fits 3/4" drives and provides a 30 mm length with a 6-point profile that ensures secure engagement with hex fasteners. Built for applications where impact-rated tools are required, the bit combines a compact length with a shape that reduces rounding and improves torque transfer when fastening or loosening bolts and nuts.

Advantages

The 6-point geometry delivers a firm grip on fastener corners, reducing cam-out and minimizing damage to bolt heads. The 30 mm length offers good access in confined spaces while maintaining stability when used with impact wrenches. Constructed and heat-treated for impact applications, the socket bit resists deformation under high torque. Compatibility with standard 3/4" drives ensures straightforward integration with common professional and heavy-duty toolsets.

Suitable for

• Maintenance and repair of heavy machinery and agricultural equipment
• Automotive wheel and suspension work requiring high torque
• Construction and assembly tasks using impact wrenches
• Workshop and industrial bolting where robust, impact-rated bits are needed

Key specifications

• Drive size: 3/4" compatible drive
• Socket length: 30 mm
• Profile: 6-point (hex) for secure fastener engagement
• Intended use: impact-rated for use with impact wrenches and drivers
• Application: suitable for high-torque fastening and loosening of bolts and nuts

How to use

Select the JCB 3/4" 30 mm 6-point socket bit and attach it securely to a compatible 3/4" impact drive or adapter. Position the socket over the hex fastener so the 6-point faces fully engage the fastener corners. When using an impact wrench, apply steady pressure and operate the tool according to the impact wrench manufacturer's instructions. Inspect the bit and fastener before and after use for signs of wear or damage and replace the bit if deformation or significant wear is observed.

Usage recommendations

Use this socket bit with impact-rated tools only and avoid hand-only use in applications beyond its intended torque range. Store in a dry, clean tool case to prevent corrosion and inspect regularly to maintain safe and reliable operation.
