Tekton impact drive extensions extend your reach. Attach an extension to your drive tool to reach past obstructions or into tight spaces. The extension works with both friction ring and detent pin anvils. Smooth walls without grooves support friction ring engagement, and a detent pin hole on one side allows you to decide whether to engage the pin. Part by part, we choose the best combination of steel alloys, heat treating specifications, and forming processes to meet the highest performance requirements. This extension has a corrosion-resistant manganese phosphate coating.
