Crimp contacts for wires. An indispensable item for any car electrician and for those who just like to mess around with the wiring themselves when installing new electrical equipment on their car. They offer both standard "mom-and-pop" terminals and those that are bolted on and are usually responsible for the ground. There are also many more different types of contact connections. Well, the advantage of such contacts is that with certain skills they can be crimped without crimping pliers, just ordinary pliers.
