Pomona1325-0 Banana Plug, SOLDERLESS, Black (Pack of 10)

Nice. Possibly M4 threads on the set screw. Side-loading wire inlet (pass-thru).You could pass a good sized bare copper wire through, and clamp in place with the set screw.Ten in a bag. Product model number easy to read off the plug, for simplified reordering.Set screws in a separate bag, enclosed inside the outer bag.Will have to assemble them yourself.A 3 mm wide, flat bladed screwdriver, 1 mm thick blade, 50 mm long shank (way longer than required, but good ergonomics) worked well.Set screw slot quite wide (blade of 1 mm thick worked, but much thicker screwdriver blade is optimal).Set screw obviously of high quality metal.

I was able to use these change the connectors on some equipment myself saving lots of money. After tightening down the screw, the wires seem very secure. Would recommend for non techie people…if I can do it anyone can.
