<💡 What is an index plunger used for? An indexing plunger serves as a reliable locating and alignment tool in machining setups. It functions by locking into position holes or detents to hold parts steady. The spring mechanism ensures smooth action while the locking feature prevents accidental movement under vibration. This design makes indexing plungers handy for holding pieces in one spot while you drill or tap. You also find these pins useful for repetitive assembly tasks where precise alignment saves time on every cycle.
