3M 7010349243 Ring Terminal 12-10 Awg Crimp 1/2 in 50 Pack

Product Description

The 3M 7010349243 is a partially insulated circular ring terminal designed for crimp connections on 12 to 10 AWG copper wire. The terminal features a copper contact with a nylon insulation sleeve and fits a 1/2 inch stud. Sold in packs of 50, this terminal is a standard choice for electricians and HVAC technicians making secure, low-resistance wire terminations at panels, equipment grounds, motor leads, and junction points. The yellow color coding identifies the compatible wire gauge range at a glance, speeding up installation and reducing mis-termination on the bench or in the field.

This ring terminal is suited for residential and light commercial electrical work, HVAC equipment wiring, control panel assembly, and general-purpose wire termination where a secure mechanical crimp to a 1/2 inch stud is required. The 12 to 10 AWG range covers common branch circuit and equipment wire sizes found in HVAC disconnects, motor wiring, and electrical panels. Each pack contains 50 terminals, making it practical for service stock or project-specific quantities.

Key Features

• Partially insulated nylon sleeve protects the wire barrel and allows visual inspection of the crimp zone
• Copper contact material provides reliable conductivity and corrosion resistance at the connection point
• Crimp connection type suits standard terminal crimping tools used in electrical and HVAC trades
• Yellow color coding identifies 12 to 10 AWG compatibility at a glance
• 1/2 inch stud size fits common lug bolts on panels, disconnects, and equipment terminals
• Pack of 50 supports service stock replenishment and multi-termination jobs

Compatibility

Designed as an OEM-style ring terminal for use with 12 to 10 AWG wire on 1/2 inch studs in standard electrical and HVAC wiring applications.

Installation Notes

Installation is performed by licensed electricians or HVAC technicians following NEC requirements for wire termination. De-energize and lock out the circuit before making any terminations. Use a calibrated ratcheting crimp tool rated for the terminal and wire gauge to ensure a gas-tight crimp. Do not over-strip the wire insulation beyond the barrel depth of the terminal.
