3M 7000133432 Locking Fork Terminal Blue 8 Stud Crimp 25 Pack

Product Description

The 3M 7000133432 is a blue, partially insulated locking fork terminal designed for crimp-style electrical connections. At 1 inch overall length and 0.03 inches thick, this terminal provides a secure mechanical lock around the stud fastener, reducing the risk of accidental disconnection under vibration or movement. The blue color coding indicates compatibility with the standard 16-14 AWG wire range typically associated with blue-coded terminals. Electricians and panel technicians use these terminals when a reliable, semi-permanent ring-style connection is needed but with the serviceability of a fork design. Each package contains 25 terminals. The terminal is CSA Certified and UL Listed, meeting the requirements of CSA LR22190 and UL File E23438.

This terminal is suited for control panel wiring, equipment grounding, and branch circuit terminations where a No. 8 stud size is used. It is commonly installed in residential and light commercial electrical systems, HVAC control boards, motor control centers, and similar low-voltage or line-voltage wiring applications. The locking fork geometry keeps the terminal seated on the stud even before the fastener is fully tightened, which is useful in tight or overhead panel work. Installation is performed by licensed electricians or qualified technicians following applicable NEC guidelines.

Key Features

• Locking fork design resists accidental disengagement from the stud under vibration
• Partially insulated construction for safe handling and streamlined termination
• Crimp connection type for fast, consistent installation with standard crimping tools
• No. 8 stud size for common panel and equipment termination points
• Blue color coding for quick visual wire-gauge identification at the termination point
• CSA Certified and UL Listed to CSA LR22190 and UL File E23438

Compatibility

Designed as an OEM-style crimp terminal for use with No. 8 stud fasteners in standard electrical wiring applications where partially insulated locking fork terminals are specified.

Installation Notes

Installation should be performed by a licensed electrician or qualified technician. De-energize the circuit and verify absence of voltage with a meter before terminating any conductors. Use a calibrated ratcheting crimp tool appropriate for the wire gauge and terminal type to ensure a gas-tight crimp. Follow NEC requirements for terminal torque on the stud fastener as specified by the equipment manufacturer.
