3M 7010397420 Ring Terminal 22-18 Awg No.8 Stud Crimp 25 Pack

Product Description

The 3M 7010397420 is a partially insulated circular ring terminal designed for crimp connections on 22 to 18 AWG copper wire. The terminal features a heat-shrink insulation sleeve in red, which aids in quick visual identification during installation. The copper contact provides reliable conductivity at the stud connection point. This terminal is suited for electrical panel wiring, control circuit terminations, and equipment grounding tasks where a secure, low-profile ring lug is required. Licensed electricians and industrial maintenance technicians are the primary installers, though HVAC and controls technicians frequently use ring terminals when landing low-voltage wiring on equipment boards.

This ring terminal is intended for use with a No. 8 stud on control panels, motor terminals, bus bars, and similar electrical termination points. The 22 to 18 AWG wire range covers light-duty control wiring commonly found in residential and light commercial electrical systems. Each package contains 25 terminals, making it practical for service calls or small installation jobs. The red color coding follows the standard industry convention for 22 to 18 AWG wire size range.

Key Features

• Partially insulated with heat-shrink sleeve for wire strain relief and insulation protection
• Crimp connection type — compatible with standard ratcheting crimp tools
• Copper contact material for reliable conductivity and corrosion resistance
• No. 8 stud size fits common panel and equipment terminal posts
• Red color coding for quick AWG range identification on the job
• UL Listed and CSA Certified — meets RoHS 2011/65/EU compliance requirements

Compatibility

Designed for use with 22 to 18 AWG copper wire on No. 8 stud terminations. Suitable as an OEM-style or replacement ring terminal for control panel wiring, instrumentation, and light commercial or residential electrical applications where partially insulated crimp lugs are specified.

Installation Notes

Installation should be performed by a qualified electrician or trained technician following applicable NEC guidelines. De-energize all circuits before terminating or replacing ring terminals. Use a properly calibrated ratcheting crimp tool sized for the 22 to 18 AWG range to ensure a gas-tight crimp — do not use pliers or open-jaw crimpers as a substitute. Inspect the heat-shrink sleeve for damage after crimping before reinstating power to the circuit.
