Ring Terminals (Eyelets)

Ring terminals, also called eyelets, fit over a bolt or stud and cannot slip off even if the nut loosens a little. That makes them the safe choice for battery, earth and terminal block connections. Packs of 50.

Terminals are colour coded by wire size: red for 3mm wire, blue for 4mm and yellow for 5mm, so you can pick the right one without measuring.

Crimp them with a ratchet crimping tool: it will not release until the crimp is complete, so every join comes out the same. Browse all types in our crimp terminals range.

Common questions

Ring or fork terminal?

A ring goes right around the bolt, so it cannot slip off even if the nut loosens. That makes it the choice for battery, earth and anything that vibrates. A fork terminal is quicker to fit because the screw does not have to come out.
