Impact Deep Socket 3/4" 77 mm 12-point — JCB

JCB impact deep socket with a 3/4" drive and a 77 mm depth is a 12-point socket engineered for use with impact wrenches and pneumatic tools. The deep profile is intended to reach recessed fasteners and long bolts while the 12-point configuration allows engagement on multiple positions of a hex fastener. The tool is offered as a durable accessory for professional automotive, construction and industrial maintenance tasks where impact-rated sockets are required.

Advantages

The socket is designed to withstand repeated impact loading and resist deformation during heavy-duty use. Its deep length provides access to recessed nuts and long-stud applications without the need for extensions. The 12-point geometry enables quicker alignment on fasteners in confined spaces and reduces time spent repositioning the tool.

Suitable for

• Removing or tightening recessed nuts and bolts on vehicles and machinery
• Work with pneumatic impact wrenches and electric impact drivers using a 3/4" drive
• Maintenance and repair tasks in construction and industrial environments

When it may not be suitable

This socket is intended for impact tool use; it may not be suitable for precision torque-controlled applications where a calibrated torque wrench is required. The 12-point design provides convenience in tight spaces but can offer slightly less surface contact than a 6-point socket on rounded or damaged fasteners, so caution is needed on stripped hardware.

Key specifications

• Drive size: 3/4"
• Socket depth: 77 mm
• Point configuration: 12-point
• Compatibility: designed for use with impact wrenches and pneumatic tools
• Typical applications: automotive, construction, industrial maintenance

How to use

Select the socket and attach it securely to a compatible 3/4" drive impact wrench. Position the deep socket squarely over the fastener and apply controlled impact force using the tool. For removal of long studs or recessed nuts, ensure the socket fully engages the fastener before applying torque. After use, inspect the socket for signs of wear or cracking and store it in a dry tool chest to prevent corrosion.

What to consider before purchase

• Confirm the drive size and socket depth match your impact wrench and the fastener accessibility.
• Verify that a 12-point socket is appropriate for the fastener condition (undamaged versus rounded heads).
• Ensure the socket material and impact rating meet the demands of heavy-duty use in professional environments.

Usage recommendations

Use this JCB 3/4" 77 mm deep impact socket only with tools rated for impact sockets. When loosening tight or corroded fasteners, apply steady, incremental force and consider anti-seize or penetrating lubricant where appropriate. Replace the socket if visible deformation or cracks appear.
