The OEX ACX3057 is a 10.5mm 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. The blue colour coding indicates compatibility with the 1.5–2.5mm² cable range. The 10.5mm ID suits M10 bolts and studs.

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 10.5mm ID ring terminal suit?
The 10.5mm internal diameter suits M10 bolts and studs (10mm nominal diameter). For M8 studs, use the ACX3056 (8.4mm ID). For M6 studs, use the ACX3055 (6.3mm ID).
What does the blue colour indicate?
Blue is the standard colour code for automotive crimp terminals suited to the 1.5–2.5mm² cable range. Always match the terminal colour to your 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, and one that grips the cable insulation — providing both a secure electrical connection and strain relief.
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.
