💡 How do you verify correct thread engagement length for heavy load electronic spacers?

You get handy results when you match the exact lead pitch to your chassis mounting holes.

- Drive the male cylinder fully into the base plate before resting the motherboard on top.
- Align the copper pillars square to the circuit traces and tighten the locking nuts step by step.
- Wipe away any metallic dust from the plating to keep the contact points clean and conductive.
- Measure the final gap with a digital gauge to guarantee zero flex during transport or vibration.
