Impact Socket Set JCB 15-piece 1" Drive Hex 36–80 mm

JCB 15-piece impact socket set with a 1" drive delivers a complete range of large hex sockets from 36 mm to 80 mm. Designed for heavy-duty fastening and loosening, these impact-rated sockets are intended for use with impact wrenches and other high-torque tools. The set covers common large fasteners encountered in industrial equipment, construction machinery, and vehicle maintenance, offering reliable contact with hex heads for efficient torque transfer.

Advantages

The sockets are impact-rated and sized from 36 mm to 80 mm to meet the demands of heavy machinery and structural assemblies. A 1" drive connection ensures compatibility with high-torque impact wrenches, improving power transfer and reducing slippage. The set arrangement of 15 sizes reduces the need to source individual sockets, saving time on job sites. Each socket is engineered for robust performance under repeated high-torque use, providing dependable service in industrial and maintenance environments.

Suitable for

• Fastening and loosening large hex nuts and bolts on heavy machinery
• Construction and structural assembly maintenance
• Commercial vehicle and trailer wheel and axle work
• Industrial plant maintenance and equipment repair

How to use

Select the socket size that matches the hex nut or bolt head and secure it onto the 1" drive of a compatible impact wrench or breaker bar. Ensure the socket is fully seated on the drive before applying torque. When using an impact wrench, apply steady, controlled bursts of power rather than continuous maximum force to maintain control and protect fasteners. Inspect sockets periodically for wear, cracking, or rounding of the hex profile and replace any damaged pieces to avoid tool or fastener damage.

Usage recommendations

Use the set with impact-rated extensions and accessories only; avoid using impact sockets with hand ratchets designed for fine torque control. Store sockets in their case or on a secure rack to prevent corrosion and maintain organization. For stubborn or rusted fasteners, apply penetrating lubricant and use appropriate safety equipment when operating impact tools.
