INCLUDES: This 3-Piece 2-Stage Impact Universal Joint set includes 1/4, 3/8, and 1/2-inch Drive U-Joint sockets that feature a 2-stage ball spring design, allowing them to quickly switch from swivel to fixed position functionality. DESIGN: These 2-Stage Impact Universal Joints feature a unique 2-stage ball design that allows each socket to swap from swivel to fixed-position function with a simple pull or push. When engaged as a swivel, these u-joints feature 360-degree rotation for superior access and reach. These sockets are made from high-strength, premium Chrome Moly steel and a black manganese phosphate finish for maximum corrosion and rust resistance. APPLICATION: Thanks to these sockets’ 2-stage design, this set offers superior versatility to traditional u-joint sockets. The swivel position of each socket enables an improved 360-degree action range of motion for easier access to hard to reach areas, while the fixed position provides standard usage.
