  • TypeElectrical Connectors

  • Brazed barrel seam resists pull-out under load
  • Tin-plated copper contact fights corrosion
  • CSA Certified and UL Listed for code compliance

3/8 in Stud Ring Terminal

This 3M M6-38RX ring terminal connects 6 AWG copper wire to a 3/8 inch stud. The bare copper barrel with tin finish is crimped for a secure electrical joint. It is rated for 1,000 V and a maximum temperature of 347 Degrees F. The component carries CSA Certified and UL Listed approvals.

Brazed Barrel Crimp Connector

The brazed barrel construction prevents the seam from opening during the crimp process. Barrel inside diameter is .25 in and barrel length is .39 in, sized for 6 AWG wire only. Tongue width measures .63 in with a hole spacing of .52 in. This design replaces loose screw-on lugs or non-brazed terminals that can split under vibration.

Bare Insulation Compatibility Check

The terminal has no insulation covering, so the installer must provide external insulation or clearance after crimping. Verify that the stud size is exactly 3/8 in and that the wire is 6 AWG copper building wire, fixture wire or sign wire. Ensure the operating voltage does not exceed 1,000 V and the ambient temperature stays below 347 Degrees F.

Questions about this item

What stud size does the 3/8 in ring terminal fit?

The terminal accepts a 3/8 in stud, with a 0.52 in hole spacing and 0.63 in tongue width for secure mounting.

Which crimp tool setting matches the 0.25 in barrel inside diameter for 6 AWG wire?

Use a crimp die sized for 6 AWG and the 0.25 in barrel ID; the brazed barrel must be fully compressed to avoid a loose connection.

When should the tin-plated copper contact be replaced due to temperature exposure?

Replace the terminal if it has been subjected to temperatures above the 347 °F maximum rating, as the tin finish and copper can degrade.
