Sta-Kon RB2233M – Frequently Asked Questions
1) What wire gauge does the Sta-Kon RB2233M fork terminal accept?
The RB2233M takes 18 to 14 AWG stranded or solid copper wire. That is the range the blue nylon insulation color codes for across the industry, so if your conductor is 16 AWG THHN or 18 AWG control wire, this is the right barrel size. For 22-16 AWG you want a red-insulated terminal, and for 12-10 AWG a yellow one.
2) What screw size does the Sta-Kon RB2233M locking fork terminal fit?
It is sized for a No. 8 screw or stud. The fork slot slips over the terminal screw without removing it, so it works on busy terminal blocks, contactor strips, and fixture whips where you can only back the screw out a turn or two.
3) What makes a locking fork terminal different from a plain spade terminal?
The locking style has turned-up or barbed tips on the fork tongue that grip under the screw head, so the terminal resists backing out if the screw loosens from vibration. A plain spade slides straight off. For panel work, motor control, or anything on a vibrating machine, the locking tongue is the one to specify; a ring terminal is still more secure but requires pulling the screw all the way out.
4) Is the insulation on the Sta-Kon RB2233M nylon or vinyl?
Nylon. Nylon insulation handles higher temperatures and takes more abuse during crimping and pulling than vinyl, which is why it is the usual choice for commercial panel and machine wiring rather than general automotive work.
5) What is the exact part number to order for the blue No. 8 Sta-Kon locking fork terminal?
Order Sta-Kon RB2233M. That one number covers the blue nylon insulated locking fork terminal for 18-14 AWG wire and a No. 8 stud; there are no finish or size options to pick on it.
6) What crimp tool do I use on the blue 18-14 AWG Sta-Kon terminals?
Use the insulated-terminal crimp die matched to the blue color code, the 18-14 AWG nest on a ratcheting or plier-style insulated terminal tool. The color-coded nests on those tools line up with the same blue/red/yellow system, so the blue die is the correct one for this barrel. Do not crimp it in an uninsulated-terminal die; that will cut the nylon sleeve.
7) Is the Sta-Kon RB2233M made in the USA?
Yes, country of origin is the United States. If you are bidding government or institutional work with domestic-content language in the spec, that is the detail the submittal will ask for.
