Tekton 3/4 in. drive impact extensions, adapters, and reducers allow you to extend your reach and expand your range. Attach an extension to your drive tool to reach past obstructions or into tight spaces. This set includes 3/4 in. drive impact extensions in 3, 6, and 10 in. lengths, along with an adapter and reducer. The extensions and adapter have a through hole that requires a retaining pin and ring to securely connect to a socket or another accessory. The reducer has a spring-loaded ball detent that lightly secures the socket by engaging its through hole. All items work with through-hole, friction ring, and detent pin anvils. The ring groove supports use with retaining rings, the smooth walls support use with friction rings, and the through hole supports use with retaining pins. All of our 3/4 in. drive sockets, extensions, adapters, and reducers are made out of 4140 steel and have a corrosion-resistant manganese phosphate coating.
