Sta-Kon C433 RING TERM 12-10 AWG NO6 BOLT

The C433 is sized for 12-10 AWG conductors. That covers standard 12 and 10 gauge building wire and stranded machine wire in the same range. If your conductor is 14 AWG or smaller, or 8 AWG and up, you need a different terminal in the series, not this one, because a crimp outside the stated range won't hold mechanically.

Bare. It's a non-insulated ring terminal, which means the crimp barrel is exposed copper alloy after you set it. If the termination sits in a panel where you need dielectric coverage or strain relief, plan on heat shrink or a boot over the barrel, or choose an insulated ring terminal instead.

It's covered under UL file E9809. That's the reference an inspector or spec writer will want on a submittal for a wire termination in a panel or control enclosure.

A ring terminal like the C433 is the choice when the connection must stay captive. The tongue is closed, so the conductor cannot back out from under a loosening screw, which is why ring terminals are required for ground connections and vibration-prone equipment. A fork or spade tongue slides out sideways without fully removing the screw, which is faster for service work on terminal strips you expect to open repeatedly. For grounding or anything that moves, go with the ring.

The C433 ring terminal cross-references to replacement product ID 7TAI029620R0042. Either designation gets you the same 12-10 AWG, #6 bolt ring terminal, so order against whichever your purchasing system carries.

Country of origin is the United States. Useful if you're buying against a domestic-preference or Buy American line item on a government, healthcare, or education project.

Yes, a non-insulated terminal needs a non-insulated crimp die, not the color-coded nests used for insulated terminals. The barrel is set with an indenter or oval die sized for 12-10 AWG. Using an insulated-terminal nest on bare barrels gives an under-formed crimp that pulls out.
