More details on the EFX Crimp-on Ring Terminals

Product Research


Overview: The Scosche EFX RT8 is a pair of ring terminals for your power cables. The terminals can accommodate 8 AWG wire. One terminal has a red rubber insulator boot, and the other has a black insulator boot. The ring has an inside diameter of 5/16".

Crimp Connector: These ring terminals must be crimped onto the end of the power wires. Because of the large diameter, a heavy duty crimping tool is recommended to make a secure crimp. You should strip the wire about 1/2" before inserting into the terminal.


  • Ring Outside Diameter: 0.483"
  • Ring Inside Diameter: 0.313" (for 5/16" or 1/4" bolt)
  • Ring Thickness: 0.034"
  • Terminal Length (w/o insulator boot): 0.946"
