Non-insulated ring terminals in copper, 12-10 AWG, 3/8 in. stud, 500 pack

  • Bare copper ensures maximum conductivity
  • Brazed seam resists pull-out under vibration
  • 12-10 AWG range covers common automotive gauges
  • 500-piece pack supports high-volume wiring jobs

3M Ring Terminal 12-10 AWG 500 Pack

These non-insulated ring terminals use copper connection material for reliable electrical joints. The pack contains 500 pieces suited for professional installers and maintenance teams handling high-volume wiring tasks. They accept wire gauges from 12 to 10 AWG and feature a 3/8 inch stud size. The brazed seam construction helps maintain barrel integrity during crimping.

Brazed Seam Thermals and Current Handling

The bare copper body dissipates heat directly into the connected conductor without an insulation barrier. Brazed seam design prevents the barrel from splitting under compression, keeping resistance stable under load. Voltage drop across the terminal remains low when crimped to specification. The open barrel allows visual inspection of the wire insertion depth before crimping.

Questions about this item

How do I crimp the 12-10 AWG ring terminal onto the wire, and what step is often missed?

Strip the wire to the correct length, insert it fully into the barrel, and use a ratcheting crimp tool sized for 12-10 AWG; the step often missed is verifying the crimp with a pull test to confirm the brazed seam holds.

What maintenance or replacement will the bare copper terminals need over time?

Inspect the .960 in. ring and barrel for corrosion or loosening periodically; if oxidation appears on the bare copper, clean the contact area or replace the terminal to maintain conductivity.
