Socket bit impact 3/4" 18 mm (6-point) JCB

Impact socket bit 3/4" 18 mm (6-point) by JCB is a heavy-duty socket designed for use with impact wrenches and pneumatic or electric impact drivers that accept a 3/4" drive. The 18 mm, 6-point configuration provides a close fit to hex fasteners, helping to transfer torque efficiently and reduce the risk of rounding. The construction and geometry are intended for repeated high-torque applications in automotive, industrial maintenance and other heavy fastening tasks.

Advantages

The 6-point profile ensures full-face contact with bolt heads and nuts, improving torque transfer and reducing slippage. Manufactured for impact use, the socket bit withstands the shock and vibration produced by impact tools. Its 3/4" drive compatibility makes it suitable for larger impact wrenches commonly used in professional workshops and industrial settings. The 18 mm size covers a frequent fastener dimension in vehicle repair and machinery maintenance.

Suitable for

• Automotive repair and wheel fastening
• Heavy machinery and equipment maintenance
• Construction and assembly of steel structures
• Industrial workshops and service bays

Key specifications

• Drive size: 3/4"
• Socket size: 18 mm
• Profile: 6-point (hex)
• Intended use: impact applications (pneumatic or electric impact drivers)
• Typical applications: heavy-duty fastening, automotive and industrial maintenance

How to use

Select the 18 mm 6-point impact socket and attach it securely to a compatible 3/4" impact wrench or driver. Ensure the socket is fully seated on the tool's drive and that the fastener is engaged squarely to the 6-point recess. Apply controlled impact torque according to the fastener specification and the tool manufacturer's guidance. After use, inspect the socket for visible wear, cracks or distortion before the next application.

Usage recommendations

Use this socket exclusively with impact-rated tools and accessories. Avoid using impact sockets with standard hand tools unless they are specifically rated for such use. Store in a dry environment to prevent corrosion and replace the socket if you observe rounding, cracking or deformation.
