How to select the right universal joint for a 1/2 in drive socket set?

Match the input and output drive size to your ratchet and socket—here both are 1/2 in. Consider the finish (black oxide resists corrosion) and whether a locking mechanism is needed for high-vibration use. The PROTO J5470AB is a non-locking square-drive universal joint suitable for general tasks.
