Multi-purpose grounding terminal set, perfect for electrical connections. These terminals are not just any terminals. They are commercially available terminals that have been gold-plated at a plating factory. It was over 10 years ago, so I don't think it was that expensive, but it might be quite costly nowadays with the rising price of gold. The sizes are varied, and the covers are missing, but I think they can be used for grounding or audio cables, so please consider them. - Type: Grounding terminal - Color: Gold - Quantity: Various - Application: For electrical connections - Sizes: Approximately 10mm, 6mm, 4mm Thank you for looking.
