These are the Heavy Duty versions of our Standard Spade Terminals. They accommodate a thicker gauge of wires, 1.20 - 3.0mm and are longer and thicker. Like the Standard variety, they have an open end which enables easy handling and quick insertion on the mounting screw. It is not necessary to remove the screw before disconnecting these terminals. They are most commonly used on studs that are free standing. We offer the Heavy Duty version with or without various insulation. You also have the choice of ordering them by loose piece or on one or more carrier types for your automated assembly.
