3PCS Universal Joint Socket Set, Chrome Vanadium Steel Swivel Socket Adapter Set, 1/4IN, 3/8IN, 1/2IN Drive Universal Joint Set

This high-quality universal joint is designed for maximum durability and convenience.

With springs added to the two fixed shafts, the angle of the joint can be kept without moving, making it more practical and efficient.

The inner wall of the groove on the driving end features small grooves that can be used in conjunction with a locking ball to securely lock the two together, preventing dislodging during use.

The optimized structure of the universal joint allows for a maximum bending angle of almost 90 degrees, making it ideal for working in narrower spaces.

Additionally, the spring-loaded locking ball keeps the universal joint set securely latched in the groove of the socket sets or extension bar, ensuring reliable performance during use.

With sizes ranging from 1/4in to 1/2in, these universal joints meet and exceed ANSI/ASME standards for compatibility with any compatible tool.
