💡 What causes spring loaded indexing plungers to fail prematurely?
Proper installation and load calculation keep retractable positioning pins running clean through messy shop floors.
- Threaded mounting holes line up straight to stop sideways bending on the stem
- Stainless alloy blocks oily coolants and salt air from eating the return spring
- Thumb pressure on the grip knob keeps the shaft from jamming deep inside
- Tossing them in a dry bin between jobs stops grit from ruining the glide race
