💡 What size indexing plunger should I pick for heavy duty equipment positioning?
You usually want a handy option that grips hard and quits rattling loose under pressure.
- Snap on the M20 fine thread build when you haul heavy tracks or machine vises that take constant side loads.
- Go smaller with M10 or M12 screws only for light duty panels that move around easy.
- Double check your frame holes before buying since stainless steel index pins bite deep and hold steady.
