Tekton 3/4 inch drive impact adapters and reducers allow you to expand your range. An adapter or reducer can help compensate for lost or broken sockets, fill in gaps for incomplete size ranges, and expand the range of your socket system. The adapter has 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. The adapter and reducer 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 inch drive sockets, extensions, adapters, and reducers are made out of 4140 steel and have a corrosion-resistant manganese phosphate coating.
