3M 7000133387 Locking Fork Terminal Blue 10 Stud Crimp 25pk

Product Description

The 3M 7000133387 is a partially insulated locking fork terminal designed for secure, vibration-resistant electrical terminations in a wide range of wiring applications. The locking fork design grips the stud to prevent the terminal from backing off under movement or vibration, making it well-suited for panel wiring, equipment interconnects, and control circuits. The crimp connection type ensures a gas-tight, low-resistance bond when applied with the correct crimping tool. At 1.0 inch overall length with a fork width of 0.32 inches and a material thickness of 0.03 inches, this terminal fits standard 10 stud sizes. The blue color coding indicates compatibility with the corresponding wire gauge range. CSA and UL certifications confirm compliance with recognized safety standards.

This terminal is used in residential and commercial electrical work wherever a reliable ring or fork termination is needed at a screw or stud connection point. Typical applications include control panel wiring, motor terminations, HVAC low-voltage control boards, and general equipment hookups requiring a removable yet secure connection. Each package contains 25 terminals, making it practical for both single-job use and small stock replenishment. Electricians and HVAC technicians are the primary installers for this type of terminal.

Compatibility

Designed for use with 10 stud fasteners in standard crimp terminal applications. Suitable for control wiring, panel boards, and equipment terminations where a partially insulated locking fork terminal is specified.

Installation Notes

Installation should be performed by a licensed electrician or qualified HVAC technician in accordance with NEC requirements. De-energize the circuit completely before terminating or removing any wiring. Use a calibrated ratcheting crimp tool rated for the wire gauge and terminal type to ensure a proper crimp; an improper crimp can result in high resistance or pull-out failure. Inspect the insulation for damage after crimping before energizing the circuit.
