3M 7000133381 Ring Terminal 12-10 Awg Crimp 3/8 Stud 25 Pack

Product Description

The 3M 7000133381 is a partially insulated circular ring terminal designed for reliable crimp connections on 12 to 10 AWG copper conductors. The terminal features a yellow heat shrink insulation sleeve and a copper contact that provides solid electrical conductivity at the lug. At 1.2 inches long and 0.59 inches wide with a 3/8 inch stud hole, it fits standard bolt terminations in panels, junction boxes, and equipment enclosures. The crimp-style connection eliminates the need for solder and delivers a consistent, gas-tight joint when installed with the correct die. Licensed electricians and experienced panel technicians are the primary installers.

This ring terminal is suited for residential and light commercial electrical work where a secure, low-resistance wire termination to a threaded stud or screw is required. Common applications include control panel wiring, grounding connections, motor leads, and equipment bonding. The 3/8 inch stud size accommodates a wide range of terminal blocks, bus bars, and chassis ground points. Each package contains 25 terminals, making it practical for multi-point termination jobs or service van stock.

Installation Notes

Installation should be performed by a qualified electrician in accordance with applicable NEC requirements. De-energize the circuit and verify zero voltage before making any terminations. Use a ratcheting crimp tool with the correct die profile for insulated ring terminals — pliers or improper tooling will not produce a reliable crimp. Inspect the completed crimp for insulation integrity and verify the ring seats flush against the stud before torquing the fastener.
