3M 7010304079 Locking Fork Terminal 1/4 Inch Stud 100 Pack

Product Description

The 3M 7010304079 is a locking fork terminal designed for secure, vibration-resistant wire terminations in electrical and control wiring applications. The partially insulated nylon body is color-coded blue, indicating compatibility with the standard blue wire gauge range for crimp-style terminals. The locking fork design keeps the terminal seated on the stud even when the fastener is loosened, which reduces the risk of accidental disconnection during service or in high-vibration environments. Termination is accomplished with a standard crimping tool, requiring no soldering. This package contains 100 terminals, suitable for stocking service vans, panels, or shop inventory.

Locking fork terminals of this type are used across residential and light commercial electrical work, HVAC control wiring, panel assembly, and equipment manufacturing. The 1/4 inch stud size fits a wide range of terminal blocks, bus bars, and equipment binding posts. Electricians, HVAC technicians, and panel builders routinely use these when a standard ring terminal is impractical and a secure, re-enterable connection is required. The blue color coding and nylon insulation make these terminals straightforward to sort and identify on the job.

Key Features

• Locking fork design holds terminal on stud when fastener is loose, reducing accidental disconnection
• Partially insulated nylon construction provides electrical isolation and durability at the connection point
• Blue color coding for quick gauge identification during installation
• 1/4 inch stud size fits common terminal blocks, binding posts, and bus bar hardware
• Crimp termination compatible with standard crimping tools — no soldering required
• CSA Certified and UL Listed; RoHS 2011/65/EU Compliant

Compatibility

Designed for use with 1/4 inch stud terminal blocks, binding posts, and equipment lugs in standard electrical panel and control wiring applications. Verify wire gauge range against 3M product documentation before installation.

Installation Notes

Installation should be performed by a qualified electrician or HVAC technician in accordance with applicable NEC requirements. De-energize all circuits before terminating or repositioning wiring. Use a calibrated ratcheting crimp tool appropriate for the terminal gauge range to ensure a secure, gas-tight crimp. Do not over-tighten the mounting fastener, as excessive torque can deform the nylon insulation collar.
