3M 7010397383 Ring Terminal 12-10 Awg 5/16 Inch Crimp 50 Pack

Product Description

The 3M 7010397383 is a partially insulated circular ring terminal designed for crimp-style electrical connections on 12 to 10 AWG copper conductors. The terminal features a copper contact and a yellow nylon insulation sleeve that covers the barrel while leaving the ring exposed for stud fastening. Built to handle the wire gauges commonly found in control wiring, panel work, and low-voltage branch circuits, this terminal provides a secure, vibration-resistant mechanical and electrical connection. It meets UL and CSA certification requirements and is RoHS compliant, making it suitable for both domestic and export installations. Each package contains 50 terminals.

This ring terminal is used wherever a reliable, semi-insulated crimp lug is required in residential, commercial, or light industrial electrical work. Typical applications include control panel terminations, equipment grounding connections, and wire harness assemblies where a 5/16 inch stud size is specified. The yellow color coding indicates compatibility with 12 to 10 AWG wire, allowing technicians to quickly confirm correct terminal selection during assembly or field service. Electricians, HVAC controls technicians, and panel wiring professionals are the primary installers.

Key Features

• UL Listed (File E23438) and CSA Certified (LR22190) — meets common code requirements for listed wiring components
• RoHS 2011/65/EU Compliant for use in restricted-substance regulated applications
• Sold in a 50-count package with a minimum order quantity of 1 package

Compatibility

Designed for use with 12 to 10 AWG copper conductors and equipment or panel studs requiring a 5/16 inch ring terminal. Standard crimp tooling rated for nylon-insulated terminals of this wire range is required for proper installation.

Installation Notes

Installation should be performed by a qualified electrician in accordance with the National Electrical Code (NEC) and any applicable local codes. De-energize and lock out the circuit before terminating any conductors. Use a ratcheting crimp tool rated for insulated terminals in the 12 to 10 AWG range to ensure a full, mechanically sound crimp — do not use pliers or non-rated tools. Inspect each completed crimp for insulation damage and confirm the ring seats flat against the stud before torquing the fastener.
