Tekton 3/4 inch drive impact universal joints allow you to reach around obstructions and access fasteners at an angle. The end of the universal joint has a spring-loaded pin detent that locks into the through hole on a socket, offering a secure connection. The joint rotates smoothly and continuously at up to a 30-degree angle. Our ball-and-socket style joint is stronger than joints that use pins. The 6-sided ball operates more smoothly than 4-lug designs. This universal joint works 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, universal joints, adapters, and reducers are made out of 4140 steel and have a corrosion-resistant manganese phosphate coating.
