Impact Deep Socket 3/4" 20 mm (12-point) JCB

Deep impact socket 3/4" drive, 20 mm, 12-point by JCB is a tool designed for demanding fastening tasks that require high torque and access to recessed nuts and extended studs. The deep profile provides extra reach compared with standard sockets, while the 12-point geometry allows quick alignment with fasteners and versatile engagement on hex heads. Intended for use with impact wrenches and pneumatic or electric impact tools, this socket balances durability and usability for professional environments.

Advantages

The socket is made for impact use, with material and heat treatment optimized for repeated high-torque applications. The deep design facilitates access to recessed fasteners and long studs without the need for extensions in many cases. The 12-point configuration permits easier positioning on fasteners in tight spaces and offers compatibility with a wider range of hex profiles. Its 3/4" drive provides robust torque transfer suitable for heavy-duty fastening and loosening.

Suitable for

• Automotive repair and maintenance — wheel nuts, suspension and drivetrain components
• Construction and assembly — structural bolting and equipment installation
• Industrial maintenance — machinery disassembly and reassembly under high torque demands
• Workshop and fleet service — frequent impact tool usage and heavy-duty fastening

Key specifications

• Drive size: 3/4" (square drive compatible with 3/4" impact wrenches)
• Socket size: 20 mm, 12-point internal profile
• Design: deep (extended length) for recessed fasteners and studs
• Intended use: impact-rated for pneumatic and electric impact tools
• Material and finish: impact-grade steel with protective surface treatment for corrosion resistance

How to use

Select the 20 mm 12-point deep socket and attach it securely to a compatible 3/4" impact wrench or breaker bar. Ensure the drive retaining mechanism on the tool (pin, ring, or detent) engages the socket square to prevent accidental disengagement. Place the socket over the fastener, making sure it seats fully on the hex profile before applying torque. When using an impact tool, apply short bursts and maintain control to prevent rounding of fasteners. After use, inspect the socket for signs of wear or cracking and store it in a dry place.
