3M 7010320649 Non-insulated Ring Terminal 10 Pack

Product Description

The 3M 7010320649 is a non-insulated ring terminal sold in a 10-piece bottle, designed for bare-wire electrical terminations in professional wiring applications. Ring terminals of this type create a secure, low-resistance connection between a wire conductor and a threaded stud or screw terminal. The M4-38RX designation indicates compatibility with M4 screw hardware and a specific wire range. Licensed electricians and experienced wiring technicians install these terminals in control panels, equipment wiring, and electrical enclosures where a clean, uninsulated crimp connection is required.

Non-insulated ring terminals are commonly used in industrial control wiring, motor control centers, switchgear, and similar applications where the installer applies their own insulation sleeve or where the connection point is housed inside an enclosure. The M4-38RX style fits M4 mounting hardware and is appropriate for both residential and light commercial panel work as well as industrial wiring tasks requiring reliable mechanical and electrical contact at a threaded fastener point.

Key Features

• Non-insulated design allows use with heat-shrink or custom insulation sleeves after crimping
• Ring tongue secures over M4 threaded studs or screws for a locked, vibration-resistant connection
• Sold in a 10-piece bottle for controlled inventory and job-site convenience
• Bare metal construction ensures direct metal-to-metal contact for low-resistance terminations
• Compact and lightweight at 0.04 pounds per unit for easy handling in tight enclosures

Compatibility

Designed for use with M4 screw and stud hardware in standard electrical termination applications. Refer to the M4-38RX specification for wire gauge range confirmation before installation.

Installation Notes

Installation should be performed by a qualified electrician in accordance with applicable NEC requirements. Always de-energize the circuit and verify zero voltage with a meter before making any terminations. Use a calibrated ratcheting crimp tool appropriate for non-insulated terminals to achieve a proper mechanical crimp. Do not solder over a crimped non-insulated terminal without verifying that the application allows it, as this can affect conductor flexibility and long-term reliability.
