best grounding washers?

(1/5) > >>

coppercone2:
If you search for grounding washer, you get a whole variety of washers.

There are the star ones (internal external) and then some washers that get weird looking, kind of like nordlock.

What are the best grounding washers?

Zeyneb:
I'm also interested in this topic. But I think know as little as you do about it. Is there a definition of what a grounding washer actually is? You want to connect a wire with an eye or fork terminal to a body of metal I assume?

coppercone2:
no just for joining two things electrically. You can have a tabbed grounding washer that you solder or crimp to a wire

Hawaka:
I think surface preparation is way more important than the washer you gonna use. If both surface are properly cleaned and all coating/paint/oxide removed, then you can use a regular washer.

If not, you probably have to think about how thick is the layer you need to pierce through before making contact. Also if you have a thick layer of paint, the connection might loosen up after some time as the paint get compressed.

pity they dont make piranha nuts smaller than 20mm
