Impact deep socket 3/4" 78mm (6-point) JCB

Deep impact socket 3/4" 78mm (6-point) by JCB is a heavy-duty fastening accessory engineered for use with impact wrenches and pneumatic tools. Its 6-point profile fits hexagonal fasteners securely, while the 78 mm length reaches recessed nuts and bolts. Manufactured to meet professional workshop and field service demands, this socket combines durability with the compatibility required for automotive, industrial maintenance and construction tasks that need a 3/4" drive solution.

Advantages

The 6-point geometry reduces rounding on hex fasteners and concentrates torque where it is most effective. Designed for impact applications, the socket resists high torque loads and repeated strikes from impact tools. The deep profile provides extended reach to access recessed or protruding fasteners, and the robust construction improves resistance to wear and deformation during heavy-duty use.

Suitable for

• Automotive repair and wheel, axle or suspension fastening
• Industrial maintenance and equipment servicing
• Construction and heavy equipment assembly
• Any application requiring a 3/4" drive and extended 78 mm socket depth

Key specifications

• Drive size: 3/4"
• Socket depth/length: 78 mm
• Point configuration: 6-point (hex)
• Designed for use with impact wrenches and pneumatic tools
• Material: impact-rated alloy steel (heat-treated)

How to use

Select the correct 3/4" drive impact wrench or adapter and attach the socket securely. Position the socket over the hex fastener and operate the impact tool at an appropriate torque setting for the application. Use short bursts when loosening strongly tightened or seized fasteners to prevent tool kickback. After use, inspect the socket for visible wear or deformation and replace if any damage is found.

Usage recommendations

Use with compatible impact-rated extensions or adapters when extra reach or clearance is needed, and avoid using the socket with non-impact hand tools to minimize the risk of cracking or premature wear. Store in a dry place and keep contact surfaces clean to prolong service life.
