Sta-Kon RB867M – Frequently Asked Questions
1) What wire sizes does the Sta-Kon RB867M ring terminal accept?
The RB867M is sized for 18 to 14 AWG stranded copper wire, which is the blue color code band on insulated terminals. If your conductor is 16 or 12 AWG you need a different barrel size, since crimping outside the 18-14 range will not hold mechanically.
2) What stud or screw size does the RB867M ring fit?
The ring tongue is a No. 8 stud size, so it drops over an 8-32 machine screw or a No. 8 terminal stud. For a 10-32 or 1/4-20 stud you would need a larger ring tongue.
3) Is a ring terminal better than a fork terminal for panel and control wiring?
A ring terminal like the RB867M is fully closed, so it cannot slip off the stud if the screw loosens. That is why it is the choice for vibration-prone work such as automotive and for panelboard and wiring harness terminations. A fork (spade) terminal installs faster because you do not have to remove the screw, but it can back out under vibration.
4) What is the barrel material on the Sta-Kon RB867M, and will it work with aluminum conductors?
The terminal barrel is copper, so it is intended for copper conductors only. Aluminum wire requires a terminal specifically marked AL or AL/CU to avoid galvanic corrosion at the crimp.
5) Does the RB867M need a special crimp tool?
Sta-Kon insulated terminals are crimped with an insulated-barrel crimping tool matched to the color code, blue in this case for the 18-14 AWG range. A plain uninsulated-terminal die will crush the vinyl and Mylar sleeve and compromise the crimp.
6) What does the Mylar insulation on the RB867M mean for temperature and abrasion?
The RB867M uses vinyl insulation with a Mylar sleeve liner over the barrel. The Mylar reinforces the insulation so the crimp area resists splitting and abrasion during pull-through in a harness, compared with plain vinyl.
7) Is the Sta-Kon RB867M made in the USA for buy-American jobs?
Country of origin on the RB867M ring terminal is the United States, which matters on federal, municipal and institutional work carrying domestic-content requirements. Order by manufacturer part number RB867M.
