3M 7100017420 Locking Fork Terminal 8 Stud Crimp 25 Pack

Product Description

The 3M 7100017420 is a locking fork terminal designed for secure, vibration-resistant electrical connections in panel wiring, control circuits, and field termination work. The partially insulated, yellow-coded body accepts 8-stud hardware and uses a crimp connection method for a reliable mechanical and electrical bond. At 1.0 inch overall length and 0.04 inches thick, the terminal fits tight terminal blocks and bus bar applications where space is limited. The 0.32-inch fork width provides consistent seating on the stud. This terminal is sold in a package of 25 and is installed by licensed electricians and instrumentation technicians.

This locking fork terminal is suited for residential and commercial electrical panel work, industrial control cabinets, and automation enclosures where terminals must remain seated under vibration or repeated service. The crimp connection is compatible with standard ratchet crimping tools. The yellow color coding follows conventional wire gauge identification practices, helping technicians quickly identify termination points during installation and maintenance.

Installation Notes

Installation should be performed by a qualified electrician in accordance with applicable NEC requirements. De-energize and lock out the circuit before crimping or seating any terminal. Use a calibrated ratchet crimping tool rated for the terminal size to ensure a full, consistent crimp. Do not attempt to solder over a crimped connection, as this can compromise the mechanical integrity of the joint.
