1.5 mm spade terminal

Spade lugs are a type of electrical terminal used to connect an electrical wire to a clamp or bolt. They consist of a cylindrical sleeve to be crimped to the electric conductor and a metal fork for connection to the terminal.
The 15 mm diameter spade lugs are suitable for cables with a cross section up to 2.5 mm². They are made of tinned copper, for greater resistance to corrosion.
