3M 7010397421 Locking Fork Terminal 6 Stud Crimp 100pk

Product Description

The 3M 7010397421 is a red, partially insulated locking fork terminal designed for crimp-style wire terminations. It features a nylon insulation sleeve and a No. 6 stud size, making it a reliable choice for securing conductors to screw terminals in electrical panels, control boards, and low-voltage wiring applications. The locking fork design holds the terminal in place on the stud, preventing accidental disconnection during vibration or routine service. Licensed electricians and HVAC controls technicians routinely use this style of terminal when wiring contactors, relays, and control circuits. This package contains 100 terminals.

This locking fork terminal is suited for residential and light commercial electrical and HVAC control wiring where a secure, reusable screw-terminal connection is required. The red color coding corresponds to the standard wire gauge range for red-coded terminals, helping technicians maintain organized, code-consistent wiring during installation and service. The No. 6 stud size fits common screw terminal posts found on control components, terminal blocks, and equipment ground lugs.

Key Features

• Locking fork design resists accidental pull-off from stud during vibration or service
• Partially insulated nylon sleeve provides dielectric protection and wire strain relief at the crimp zone
• No. 6 stud size fits standard screw terminal posts on control boards and terminal blocks
• Red color coding supports organized, gauge-consistent wiring practice
• CSA Certified and UL Listed under UL File E23438 for use in listed assemblies
• RoHS 2011/65/EU compliant

Compatibility

Designed as an OEM-style crimp fork terminal for use with No. 6 screw studs in electrical control wiring applications. Suitable for use wherever a partially insulated, nylon-sleeved locking fork terminal is specified.

Installation Notes

Installation should be performed by a qualified electrician or HVAC technician in accordance with the NEC and applicable local codes. De-energize the circuit completely before crimping or terminating any conductors. Use a ratcheting crimp tool rated for insulated terminals to achieve a consistent, gas-tight crimp. Inspect the nylon sleeve after crimping to confirm no cracking or deformation has occurred before tightening the stud fastener.
