Sta-Kon RF10731U – Frequently Asked Questions
1) What wire size and stud size does the Sta-Kon RF10731U ring terminal take?
The RF10731U is built for No. 4 AWG conductor and a 3/8 inch stud or bolt. If your cable is a different gauge, use the matching Sta-Kon part instead, because the barrel is sized to crimp on 4 AWG only and an undersized conductor in it won't hold a proper crimp.
2) Can I crimp a 4 AWG Sta-Kon ring terminal with regular hand pliers?
No. A 4 AWG barrel needs a heavy crimp tool or hydraulic/ratcheting crimper with a die sized for that range. Standard insulated-terminal hand pliers made for 22-10 AWG won't close the barrel on the RF10731U, and a partial crimp on a 3/8 inch stud connection is a heat and failure point. Order the correct die set with the terminals.
3) Why would I pick a 90 degree ring terminal instead of a straight one?
The RF10731U has a 90 degree bend between the barrel and the ring tongue, so the cable runs parallel to the mounting surface while the ring lands flat on the stud. That is what you want in a tight panel, breaker gutter, or battery box where a straight terminal would force a hard bend in 4 AWG cable right at the crimp. If you have room to come straight onto the stud, a straight ring terminal is the simpler choice.
4) Is the insulation on this Sta-Kon ring terminal nylon or vinyl?
Nylon. The RF10731U uses a nylon insulating sleeve, which holds up better to abrasion and hot panel temperatures than a soft vinyl sleeve and resists cracking when the barrel is crimped.
5) What does the yellow color on this ring terminal mean?
Yellow is the standard color code for the 12-10 AWG insulated terminal range on most lines, but on the RF10731U the yellow sleeve goes with a No. 4 AWG barrel, so don't size by color here. Go by the printed part number and the 4 AWG / 3/8 inch stud rating.
6) Where is the Sta-Kon RF10731U made?
Country of origin for the RF10731U is listed as Mexico or the United States, which matters if you're submitting on a job with domestic sourcing requirements and need to confirm origin on the packaging you receive.
7) Is this a ring terminal or a fork terminal?
It's a closed ring (circular tongue), not a slotted fork or spade. The nut has to come off the stud to install it, but once it's torqued down the connection can't vibrate off the stud the way a fork terminal can, which is why rings are specified for battery, motor, and bus connections.
