3M 7100164164 Ring Tongue Terminal 4 Awg 1/2 Inch Stud

Product Description

The 3M 7100164164 is a non-insulated ring tongue terminal designed for permanent, secure electrical connections in professional wiring applications. It features a brazed seam construction and accepts 4 AWG wire with a 1/2 inch stud size. The ring tongue style fully encircles the mounting stud, making it the most mechanically secure terminal type available — it cannot be dislodged unless the fastener is removed. Electricians and maintenance technicians install this terminal where vibration resistance and connection integrity are critical priorities.

This terminal is suited for residential and commercial electrical work, panel wiring, grounding connections, and industrial equipment terminations where bare copper lugs are appropriate. The non-insulated design allows for post-installation inspection of the wire crimp and is commonly used where terminals will be covered by a separate insulating sleeve or housed within an enclosure. Sold in quantities of 200 per case, it is well suited for contractors and service shops keeping stock on hand for recurring wire termination work.

Key Features

• Brazed seam barrel construction for a strong, consistent crimp connection
• Ring tongue style fully encircles the stud, preventing accidental disconnection
• Non-insulated design allows visual crimp inspection after installation
• Accepts 4 AWG wire with a 1/2 inch stud size
• Packaged in quantities of 200 per case for shop and contractor stocking

Compatibility

Designed as an OEM-style ring tongue terminal for use with 4 AWG conductors and 1/2 inch mounting studs in standard electrical termination applications.

Installation Notes

Installation is performed by a licensed electrician in accordance with NEC requirements. De-energize the circuit completely before terminating or repositioning any conductors. Use a calibrated ratcheting crimp tool rated for non-insulated terminals at the appropriate AWG range to ensure a full, uniform crimp. Do not over-crimp or use pliers as a substitute for a proper crimping tool, as this can compromise the barrel integrity and increase resistance at the connection point.
