2020/21 What's the best 100A Peak Pack?

If the screws are steel, then they are a poor conductor with high resistance. They can be useful as a current-limiting resistor, as long as the resistance value does not need to be precise.
 
A couple steel screws doesn’t seem a big deal and was surprised to find the kweld uses them. If they’re big enough maybe the conductance creeps up to equivalent to a decent conductor.

Gotta buy that cheap precision resistance tester.
