These XS-008 spades from Xangsane are good quality. The copper alloy contacts are plated with 24k gold. Conductivity is therefore optimal, and the plating ensures resistance to corrosion and oxidation. The connectors' shells are also made of copper, ensuring good durability. These XS-008 spade connectors from Xangsane have an 8mm spacing. They are screw-type and accept cable diameters up to Ø8mm. Two screws on the sides of the spade firmly secure the cable.
