3M 7010304204 Locking Fork Terminal 1/4 Inch Stud Crimp 25pk

Product Description

The 3M 7010304204 is a locking fork terminal designed for secure, vibration-resistant electrical connections in trade and industrial wiring applications. The partially insulated, crimp-style design accepts a 1/4 inch stud and provides a 0.43 inch fork width for positive seating on terminal posts. Overall length is 1.1 inches with a 0.03 inch material thickness. The blue color coding indicates compatibility with the standard mid-range wire gauge group. Heat shrink insulation at the barrel adds strain relief and protects the crimp zone. This terminal is well suited for panel wiring, control circuit terminations, and equipment grounding connections where a locked, low-profile fork lug is required.

Locking fork terminals see regular use in HVAC control panels, electrical distribution equipment, motor control centers, and commercial building automation wiring. The crimp termination method is preferred in professional installations for its consistency and pull-out resistance compared to mechanical screw-down lugs. Electricians and HVAC controls technicians typically use these when terminating low-voltage control wiring to bussed terminal strips or grounding studs. This SKU ships in a pack of 25, making it practical for service trucks and panel build jobs requiring multiple identical terminations.

Key Features

• Locking fork design prevents terminal from lifting off stud under vibration
• Crimp connection type for consistent, repeatable terminations
• Partially insulated with heat shrink insulation at the barrel for strain relief
• Blue color coding for quick wire gauge identification at the panel
• CSA Certified and UL Listed — meets CSA LR22190 and UL File E23438
• Pack of 25 for multi-point termination jobs

Compatibility

Designed as an OEM-style locking fork terminal for use with 1/4 inch threaded studs in standard crimp terminal applications across residential and commercial electrical and HVAC control wiring.

Installation Notes

Installation should be performed by a licensed electrician or qualified HVAC controls technician in accordance with NEC requirements for the circuit type and voltage class involved. De-energize and lockout the circuit before terminating or inspecting any wiring. Use a calibrated ratcheting crimp tool sized for the terminal barrel to achieve a proper crimp — an undersized or hand-squeeze crimp risks high-resistance joints and pull-out failure. Do not attempt to solder over a crimp on this terminal type, as heat can compromise the insulation sleeve.
