Impact Socket 3/4" 78 mm 6‑point by JCB

JCB impact socket with a 3/4" square drive and 78 mm overall length, configured as a 6-point socket for secure engagement with hex fasteners. It is engineered for use with impact wrenches and pneumatic or electric torque tools, providing a robust connection between the tool and the fastener for heavy-duty fastening and loosening operations in automotive, construction, and industrial maintenance environments.

Advantages

The 6-point design concentrates contact on the flats of hex fasteners to reduce rounding and improve torque transfer. A heavy-duty construction suited to impact use provides enhanced durability under repeated high-torque cycles. The 3/4" drive size is compatible with larger impact wrenches and torque tools commonly used for high-torque applications, while the 78 mm length offers balance between reach and control on fasteners in moderately recessed positions.

Suitable for

• Removing and tightening large hex nuts and bolts in automotive repair and heavy vehicle maintenance
• Construction site bolting and structural assembly tasks requiring impact tools
• Industrial maintenance where repeated high-torque operations are performed
• Pneumatic or electric impact wrench applications on heavy machinery

Key specifications

• Drive size: 3/4" square drive
• Socket length: 78 mm
• Point configuration: 6-point (hex)
• Intended use: impact-rated for use with impact wrenches and torque tools
• Material and finish: heavy-duty construction suitable for high-torque applications

How to use

Fit the socket onto the 3/4" square drive of a compatible impact wrench or breaker bar, ensuring the socket is fully seated on the tool's drive. Place the socket over the hex fastener and apply controlled impact or torque according to the fastener and tool specifications. For removal, select the appropriate direction on the impact tool and use short bursts of power to avoid sudden shock to adjacent components; for tightening, use torque-limiting equipment if a precise final torque is required.

Usage recommendations

Inspect the socket for cracks, deformation, or wear before each use. Use appropriate personal protective equipment and follow tool manufacturer guidelines. Match the socket to the correct fastener size and avoid using a worn socket on rounded fasteners to prevent damage to both the tool and the workpiece.
