3M 7010398218 Locking Fork Terminal Red 10 Stud Crimp

Product Description

The 3M 7010398218 is a red, partially insulated locking fork terminal designed for secure, vibration-resistant electrical connections in both residential and commercial wiring applications. The crimp-style connection provides a reliable mechanical and electrical bond without soldering. The terminal features a 0.32-inch fork width, an overall length of 1.0 inch, and a 0.03-inch thickness. Heat shrink insulation at the barrel adds environmental protection and strain relief at the wire entry point. This terminal is commonly installed by electricians, panel technicians, and equipment service professionals who require a dependable ring-style fork connection to a number 10 stud.

This locking fork terminal is suited for general-purpose electrical termination work where a number 10 stud size is required. The red color coding indicates compatibility with the applicable wire gauge range for this terminal series. Typical applications include control panel wiring, equipment grounding, and branch circuit terminations in industrial, commercial, and residential settings. The partially insulated design allows visual inspection of the wire insertion depth before crimping, which is useful during quality checks on production or service work.

Key Features

• Locking fork design resists pull-off and vibration loosening at the stud
• Crimp connection eliminates the need for soldering
• Heat shrink insulation at the barrel provides strain relief and moisture resistance
• Partial insulation allows visual confirmation of wire seating before crimping
• Red color coding for quick gauge identification during installation
• CSA Certified and UL Listed for use in listed and labeled assemblies

Compatibility

Designed as an OEM-style replacement or standard-use locking fork terminal for number 10 stud applications in listed electrical assemblies requiring CSA and UL compliance.

Installation Notes

Installation is typically performed by licensed electricians or qualified equipment technicians. De-energize and lock out the circuit before terminating or inspecting connections, in accordance with NFPA 70 (NEC) lockout/tagout requirements. Use a calibrated ratchet crimp tool rated for the terminal and wire gauge to ensure a full, consistent crimp. Do not over-strip the wire insulation or seat the terminal before confirming proper wire insertion depth.
