💡 Why do technicians recommend spring return ball lock pins for custom fixture setups?
These indexing pins are pretty handy for keeping parts steady while you weld or machine them. You get consistent hold-down force without clamping interference.

- Keep the guide hole clean so the stainless ball bearing moves freely
- Lubricate the plunger shaft occasionally to prevent sticky spring resistance
- Swap to larger diameters when you need heavier load capacity during fabrication
