Premium CR-MO: This impact extension bar set is made from premium CR-MO steel and heat-treated for high strength and excellent toughness. The surface is coated with black manganese phosphate to resist rust and corrosion for enhanced durability, and laser-etched brand and size markings are easy to read.

Multiple Sizes: This 1/2" extension set includes three commonly used sizes—3", 6", and 8"—to handle different fastening tasks and applications.

High Compatibility: This 1/2" drive extension set is compatible with electric, pneumatic, and manual ratchets, breaker bars, and other 1/2" square drive tools for versatile use across a wide range of applications.

Comfortable & Ergonomic Design: The drive end has a multi-purpose pinhole to ensure the extension bar can be firmly seated on the drive handle. The end of the impact extension bar has a detent ball that forms a locking mechanism that prevents the extension bar from falling, increasing its stability and safety.

Reach Hard-to-Access Fasteners: This 1/2" impact extension set helps extend the reach of your tools to access deep or hard-to-reach fasteners, improving efficiency for automotive repair, equipment maintenance, and assembly applications.
