Deep Impact Socket 3/4" 43mm 12-Point — JCB

Deep impact socket 3/4" 43mm 12-point by JCB is a heavy-duty socket made for use with 3/4-inch drive impact wrenches and ratchets. The deep-well design allows access to recessed nuts and studs while the 12-point geometry provides multiple engagement positions for faster alignment on fasteners. Constructed to withstand impact forces typical in automotive, construction, and industrial maintenance environments, this socket is intended for repeated use with impact-rated tools where higher torque and durability are required.

Advantages

The deep profile enables reach to recessed or long-stud fasteners without the need for extensions, while the 12-point configuration simplifies positioning on hex heads and other compatible fasteners. The socket is impact-rated, designed to tolerate the high torque and shock of impact wrenches, and its construction aims to provide consistent contact with fasteners to reduce rounding. Its compatibility with a 3/4-inch drive makes it suitable for common heavy-duty impact tools used by professionals.

Suitable for

• Automotive heavy-duty repairs and wheel nut removal
• Construction equipment maintenance and assembly
• Industrial machinery servicing and fastening tasks
• Workshops and service fleets that use impact wrenches

Key specifications

• Drive size: 3/4 inch
• Socket diameter: 43 mm
• Point configuration: 12-point
• Design: deep (deep-well) socket
• Intended use: impact-rated for use with impact wrenches and impact-rated ratchets

How to use

Select the socket and fit it onto a compatible 3/4-inch drive impact wrench or ratchet. Ensure the socket fully seats over the fastener before applying torque. When using an impact wrench, apply short bursts of power and verify engagement periodically to prevent slipping. For removal of stuck or corroded fasteners, use controlled torque increments and consider applying penetrating lubricant and heat as appropriate for the fastener material and assembly. After use, inspect the socket for wear or cracking and replace if any damage is found.

Usage recommendations

Use only with impact-rated tools and accessories; do not use this socket with non-impact hand tools unless the socket is explicitly marked for such use. Wear appropriate personal protective equipment when working with impact tools and follow the torque limits and safety guidelines of your impact wrench and fastener specifications.
