OEX ACX3055 Crimp Terminal Ring Blue ID 6.3mm Vinyl 100 PCE

OEX ACX3055 6.3mm ID Ring Crimp Terminal Blue Vinyl 1.5 to 2.5mm² Double Crimp M6 Stud Pack of 100

The OEX ACX3055 is a 6.3mm ID ring crimp terminal in blue vinyl, supplied in a pack of 100. Ring terminals provide a secure bolted connection to studs, posts and terminals the ring loop is placed over the fastener before tightening, creating a connection that cannot pull free. Double crimp construction provides both a cable crimp and an insulation crimp. Tin plated copper ensures reliable conductivity. Blue colour coding indicates the 1.5 to 2.5mm² cable range. The 6.3mm ID suits M6 bolts and studs. Covered by a one year warranty.

Product overview

Ring terminals are the preferred choice for battery connections, chassis earth points and other permanent connections where accidental disconnection would be problematic. Unlike blade or bullet terminals, the ring loop requires the fastener to be removed for disconnection the terminal is physically locked in place when the bolt or nut is tightened. This makes ring terminals the standard for battery lugs, chassis earths, circuit breaker studs, fuse box posts and other bolted connection points.

The 6.3mm internal diameter suits M6 bolts and studs (6mm nominal diameter). The blue vinyl insulation follows the standard automotive terminal colour convention for the 1.5 to 2.5mm² cable range. The double crimp grips both the bare conductor and the cable insulation for a secure electrical connection with strain relief. A ratchet crimping tool designed for insulated terminals in the blue range is recommended. The pack of 100 suits trade workshops.

Frequently asked questions

What is a ring terminal used for? A ring terminal provides a secure bolted connection. The ring loop is placed over a bolt or stud before the fastener is tightened, locking the terminal in place. Unlike spade or blade terminals, ring terminals cannot accidentally pull free, making them the preferred choice for battery connections, chassis earths and other permanent connections.

What bolt size does a 6.3mm ID ring terminal suit? The 6.3mm internal diameter suits M6 bolts and studs (6mm nominal diameter). For M5 or M8 studs, a ring terminal with the corresponding ID is required.

What does the blue colour indicate? Blue is the standard colour code for automotive crimp terminals suited to the 1.5 to 2.5mm² cable range. Always match the terminal colour to the cable size for a correct crimp.

What is a double crimp terminal? A double crimp terminal has two crimp zones: one that grips the bare conductor for the electrical connection, and one that grips the cable insulation for strain relief, preventing the terminal from pulling off the cable under tension.

Are these terminals available in other sizes or colours? OEX produces ring terminals in a range of ID sizes and cable ranges. Check the OEX terminal range for other available options.
