💡 What helps an indexing plunger stay locked under heavy side loads?
Your setup needs consistent stopping points that handle shop vibrations without backing off. Here is how this pin delivers that performance:
- Fine pitch cutting threads bite deep into steel housings for solid torque retention.
- The coiled spring inside keeps tension steady while absorbing impact bumps.
- Protective grooves filter grit so the locking rod glides smooth every time.
