can't think of the name of them but I usually tap the hole & substitute 4-40
button screws

Does anyone know the proper name for the rivet ( pin ) type , round head
fastners with spiral shank, that are used to attach metal plates to
equipment ? You drill a blind hole and drive them in.

I need to purchase some, but cannot find them, due to not knowing what
name to look for.

TIA
