Impact Socket Bit 3/4" 20 mm (6-point) - JCB

JCB impact socket bit 3/4" (20 mm) with a 6-point profile is a replaceable drive accessory engineered for use with compatible impact wrenches and drive tools. It is intended for fastening and loosening bolts and nuts of 20 mm size where impact-rated performance and reliable engagement are required. The socket bit features a 6-point internal geometry to provide full-face contact with fasteners, reducing the chance of rounding and improving torque transfer during heavy-duty operations.

Advantages

The 6-point profile provides secure contact with bolt heads and nuts, minimizing slippage under high torque. Designed for impact applications, the bit withstands repeated shock loads from impact wrenches. Its standard 3/4" drive connection ensures compatibility with a wide range of impact tool holders and extensions. The compact replaceable design allows quick swapping in multi-bit holders and reduces downtime during maintenance tasks.

Suitable for

• Automotive repair and wheel fastening where 20 mm fasteners are used
• Construction machinery maintenance and assembly work requiring impact-rated tools
• Mechanical workshops and industrial maintenance involving high-torque nut and bolt work

Key specifications

• Drive size: 3/4" (drive connection compatible with 3/4" impact tools)
• Bit size: 20 mm (suitable for 20 mm hexagonal fasteners)
• Profile: 6-point internal geometry for full-face engagement
• Designed use: impact-rated applications with repeated shock loading

How to use

Select the 20 mm 6-point impact socket bit and securely attach it to a compatible 3/4" impact tool or adapter. Ensure the drive connection locks into place and position the bit squarely on the fastener head before applying torque. Use appropriate torque settings and impact tool controls for the fastener material and grade. After use, inspect the bit for wear or deformation and replace it if signs of rounding or cracking appear.

Usage recommendations

Use eye protection and follow manufacturer guidelines for your impact wrench. Match the bit to the correct fastener size and avoid applying excessive torque beyond the fastener or tool ratings. Store the socket bit in a dry tool organizer to prevent corrosion and check regularly for wear when used in frequent impact operations.
