Frequently Asked Questions

What is a 3M M8-12R/SK ring terminal used for?

The 3M M8-12R/SK is a non-insulated ring terminal used for high-reliability electrical connections in industrial control panels, machinery, and power distribution. Its brazed barrel and seam design handles up to 1,000 V, making it suitable for heavy-duty applications requiring secure, vibration-resistant terminations.

What are the specifications of the 3M M8-12R/SK ring terminal?

The 3M M8-12R/SK ring terminal has a 1/2 in stud size, accepts 8 AWG wire, and is rated for 1,000 V. It features a brazed barrel and seam construction for durability. The bare copper design allows for custom insulation or direct grounding in industrial environments.
