Impact socket set ROCKFORCE / WMC RF-6212-9MPB 21-piece 3/4" drive 12-point 17–50 mm

The ROCKFORCE / WMC RF-6212-9MPB 21-piece impact socket set offers a comprehensive range of 12-point sockets with a 3/4" drive, covering sizes from 17 mm to 50 mm. Designed for use with impact wrenches and compatible pneumatic or electric impact tools, this set is intended for tasks that require reliable engagement with large fasteners and the ability to withstand high torque during loosening and tightening operations.

Advantages

This 21-piece impact socket set provides a wide size range that reduces the need for multiple individual sockets. The 12-point configuration allows for easier alignment on fasteners in confined spaces, while the 3/4" drive is suitable for heavy-duty torque delivery from impact tools. Sockets are designed to be compatible with common impact wrenches and to handle repeated shock loading associated with pneumatic and electric impacts.

Suitable for

• Automotive maintenance on trucks and heavy vehicles
• Industrial machinery assembly and repair
• Construction and heavy equipment maintenance
• Workshop use with pneumatic or electric impact wrenches
• Field service and mobile repair operations

• Intended use: impact-rated sockets for high-torque applications

How to use

Select the socket corresponding to the fastener size and attach it securely to a 3/4" drive impact wrench. Ensure the socket is fully seated on the tool square drive before applying torque. When loosening or tightening, apply short bursts with the impact tool to control torque application and avoid over-torquing. Inspect sockets for cracks or deformation before use and replace any socket that shows damage. Use appropriate personal protective equipment, including eye protection and gloves, when operating impact tools.

Usage recommendations

For reliable performance, use these sockets only with impact-rated extensions and accessories. Avoid using impact sockets with hand ratchets or cheater bars for static leverage beyond the tool's rated capacity. Store sockets in a dry, organized case to prevent corrosion and to keep sizes readily accessible for workshop or field tasks.
