3M 7100135166 Ring Tongue Terminal 6 Awg 3/8 Stud

Product Description

The 3M 7100135166 is a non-insulated, brazed-seam ring tongue terminal designed for secure, permanent electrical connections in industrial and trade wiring applications. Rated for 6 AWG wire and a 3/8 inch stud size, this terminal uses a closed-ring tongue style that prevents accidental disconnection — the ring cannot be removed without first removing the mounting screw or fastener. The brazed seam construction provides a solid barrel that resists splitting during crimping. Electricians and maintenance technicians use this style of terminal where connection integrity and vibration resistance are priorities.

This terminal is suited for panel wiring, equipment grounding, and power distribution connections where a reliable, non-insulated ring lug is required. The 6 AWG wire range makes it appropriate for branch circuit and equipment termination work in both residential and light commercial settings. It is sold in cases of 200, making it a practical stocking item for contractors and service shops that terminate ring connections regularly.

Key Features

• Closed ring tongue style — connection stays secure unless mounting fastener is removed
• Brazed seam barrel construction resists splitting during crimping
• Accepts 6 AWG wire
• Fits 3/8 inch stud size
• Non-insulated design for use with separate sleeve or heat-shrink insulation where required
• Sold in quantities of 200 per case

Compatibility

Designed as a standard non-insulated ring tongue terminal for 6 AWG wire terminations on 3/8 inch studs, suitable for use in general electrical panel, grounding, and equipment wiring applications.

Installation Notes

Installation is performed by licensed electricians or qualified maintenance personnel. De-energize the circuit and verify zero voltage with a meter before terminating. Use a calibrated ratcheting crimp tool appropriate for the wire gauge and terminal type to ensure a proper mechanical and electrical crimp. Follow NEC requirements for terminal insulation, conductor sizing, and torque specifications for the mounting hardware.
