Sta-Kon K973PF – Frequently Asked Questions
1) What wire size does the Sta-Kon K973PF ring terminal take?
The K973PF is sized for 2/0AN through 3/0 AWG conductor. It's a heavy power lug, not a control-wire terminal, so if you're landing anything smaller than 2/0 you want a different barrel size entirely. Crimp barrels are sized to the conductor, and a 3/0 barrel will not hold 1/0 reliably even with a double crimp.
2) Will the K973PF ring fit a 3/8 inch stud or bolt?
Yes. The K973PF is built with a 3/8 inch bolt hole, so it lands directly on a 3/8 inch stud, breaker lug pad, or ground bar bolt. On a larger stud it won't go on; on a smaller bolt you'd be relying on a washer to take up the slack, which is poor practice on a power connection.
3) Is the Sta-Kon K973PF insulated?
No, it's a bare non-insulated ring terminal. Nothing covers the barrel or the tongue, so you insulate it yourself after crimping, normally with adhesive-lined heat shrink or tape, and you need to account for clearance to adjacent phases and to the enclosure. Buyers who want the insulation built in should be looking at an insulated ring terminal instead.
4) What is the K973PF terminal made of, and does the unplated finish matter?
Copper barrel and tongue, supplied unplated. Bare copper is fine in dry indoor gear, but with no tin plating there's nothing slowing oxidation, so in damp, outdoor, or marine work you either seal the joint or pick a tin-plated lug. Unplated copper also means you should use an oxide-inhibiting compound if you're landing on an aluminum pad.
5) Can I install the Sta-Kon K973PF with hand crimpers?
Not realistically. At a 2/0 to 3/0 barrel this is a hydraulic or heavy mechanical crimp tool job with the matching die; hand-squeeze crimpers are for insulated and small non-insulated terminals. Plan on a battery or hydraulic crimper on the truck before you order these.
6) Is a ring terminal like the K973PF better than a fork terminal for a panel connection?
For a 3/0 feeder or a main bonding jumper, a ring is the right call. The closed tongue on the K973PF can't vibrate off the stud if the nut backs off, where a fork or spade can slide out from under a loose screw. Forks exist for speed on terminal strips you service often, which is not what a 3/0 copper lug is doing.
7) How do I order the exact Sta-Kon heavy ring lug by part number?
Order it as Sta-Kon K973PF. That single part number covers the whole configuration, bare copper, unplated, 2/0AN-3/0 barrel, 3/8 inch bolt hole, so there are no finish or size options to specify on top of it. Country of origin is Mexico, which matters if you're filing origin documentation on a government or institutional job.
