What the hell are these called?

The little grounding springs for PCB to enclosure. I have some, I just can't remember where I got them or what they are actually called.

Ah okay, they are just battery contacts. Had a senior moment.

For the ones that are not just repurposed battery contacts, I believe they are called "grounding contacts". Battery contacts are probably more plentiful and cheaper though.

[lars]

 "Solderless negative electron pathway constructor bridge" or "doohickey" for short.

[alanp]

Some common terms are "Whatchamacallit", "Thingameebob" or, in extremity, "F---ing bl---- piece of g------ sh--."

[matmosphere]

I believe the technical term is a Faflapathong

[madbean]

I found a cheap alternative. Not the sturdiest piece of kit but should work for what I'm needing.

When I change my guitar strings, I have a few of those lying around afterward.  I've always just thrown them away, but now I know they are worth $0.10 apiece.

You use too many wraps, then!
