3M 7010349242 Ring Terminal 12-10 Awg Crimp 1/4 in Stud 50 Pack

Product Description

The 3M 7010349242 is a partially insulated circular ring terminal designed for crimp-style wire terminations on copper conductors. It accepts 12 to 10 AWG wire and terminates onto a 1/4-inch stud. The nylon insulation sleeve provides mechanical protection at the barrel entry while leaving the ring exposed for direct metal-to-metal contact at the stud. Electricians and low-voltage installers use these terminals when making secure, vibration-resistant ring connections to bus bars, grounding studs, or equipment terminals. Each package contains 50 pieces.

These ring terminals are suited for residential and light commercial electrical work, panel terminations, grounding connections, and equipment wiring where a reliable crimp ring lug is required. The yellow color coding corresponds to the 12 to 10 AWG range, allowing technicians to quickly verify correct terminal selection during installation. The copper contact material ensures low-resistance conductivity consistent with standard wiring practice.

Key Features

• Partially insulated nylon barrel protects the crimp zone while maintaining full ring contact at the stud
• Compatible with 12 to 10 AWG copper conductors
• 1/4-inch stud size fits common grounding and equipment terminal hardware
• Yellow color coding for quick AWG range identification
• Copper contact material for reliable, low-resistance termination
• Crimp connection type — no soldering required

Compatibility

Designed as an OEM-style ring terminal for use with 12 to 10 AWG copper wire on 1/4-inch threaded studs in standard electrical, HVAC control wiring, and panel grounding applications.

Installation Notes

Installation should be performed by a qualified electrician in accordance with the NEC. De-energize and lock out the circuit before terminating any conductors. Use a calibrated ratchet crimping tool rated for insulated ring terminals to ensure a complete, gas-tight crimp — do not use pliers or uncalibrated tools. Verify stud torque requirements per the equipment manufacturer specification before tightening the ring lug.
