Impact Socket 3/4" 79 mm (6-point) JCB

Impact Socket 3/4" 79 mm (6-point) JCB is a heavy-duty drive socket designed for use with 3/4-inch impact wrenches and torque tools. The 6-point profile ensures positive engagement with hexagonal fasteners, reducing the risk of rounding. With a 79 mm overall length, this socket balances access to recessed nuts and the robustness required for high-torque applications in automotive, construction and industrial maintenance environments.

Advantages

The 6-point geometry provides a secure grip on fasteners and minimizes slippage under impact loading. Constructed for impact use, the socket withstands repeated shock and high torque from pneumatic and electric impact wrenches. The 3/4" drive size offers compatibility with a wide range of professional torque tools. Its compact 79 mm length allows access in tighter spaces while maintaining sufficient wall thickness for durability.

Suitable for

• Automotive repair and wheel nut removal where high torque is needed
• Heavy equipment and machinery maintenance
• Industrial assembly and disassembly with impact tools
• Field service work using pneumatic or battery impact wrenches

Key specifications

• Drive size: 3/4 inch
• Length: 79 mm
• Profile: 6-point (hex)
• Intended use: impact-rated for pneumatic and electric impact wrenches
• Typical applications: high-torque fastening and loosening

How to use

Fit the 3/4" drive of the impact socket onto the anvil of a compatible impact wrench and seat the socket fully onto the fastener head. When loosening or tightening, apply intermittent operation and control impact tool torque settings as appropriate for the fastener and application. Inspect the socket for visible wear or cracking before use and replace if any damage is present. Use appropriate personal protective equipment, including eye and hand protection, when operating impact tools.

Usage recommendations

Use with impact-rated extensions or adapters when extra reach is required, and avoid using the socket with hand ratchets or breaker bars if it is rated solely for impact use. Store in a dry toolbox to prevent corrosion and routinely inspect contact surfaces for rounding or deformation to maintain safe engagement with fasteners.
