Sta-Kon C115NP NICKEL PLATED FORK 12-10 WITH NO10

The C115NP is sized for 12-10 AWG stranded copper conductors. If you're terminating 14-16 AWG control wire, it will crimp loose and won't hold tension, so step down to a terminal rated for that smaller range instead.

Yes. The C115NP fork (spade) tongue is made for a No. 10 stud or screw, which is the common size on contactor terminals, panel lugs, and motor terminal blocks. The open fork slides under a partly backed-off screw rather than needing the screw fully removed.

It's a non-insulated terminal, bare metal right up to the crimp barrel. In a tight enclosure where terminals sit close together, you'll want heat shrink or a nylon sleeve over the barrel, or choose an insulated fork instead. Non-insulated is the right call when you need a high-temperature termination or you're applying your own shrink.

Copper barrel with a nickel plating. The copper gives you the conductivity and crimp ductility; the nickel plate is what makes this one suited to higher-temperature and corrosive service, where a tin-plated terminal would degrade.

A fork like the C115NP lets you loosen the screw and slide the lug in, which saves real time on panel work and retermination. A ring terminal is captive and won't back out if the screw loosens, so it's preferred on vibrating equipment and where a code or spec calls for a closed tongue. Same 12-10 AWG wire, same No. 10 screw, different maintenance tradeoff.

Yes, a non-insulated terminal crimps with the bare-lug dies of a ratcheting or plier-type crimper, not the color-coded insulated nests. Using the insulated jaw on a bare barrel gives an under-formed crimp. Match the die to the 12-10 AWG range.

Order Sta-Kon C115NP. That single model number covers the nickel plated, non-insulated fork for 12-10 AWG wire with the No. 10 stud opening, so there are no plating or size suffixes to specify.
