💡 How do spring plungers improve jig alignment accuracy?
Your shop depends on these mechanical locks to keep workpieces perfectly still during drilling or welding operations. You get reliable positioning every time you press them into place.
- Internal return springs maintain constant contact pressure against uneven metal surfaces
- Coarse thread pitch ensures fast installation and resists cross threading in soft aluminum plates
- Self-centering pin geometry reduces parallax errors when aligning complex fixture layouts
