Description
OEX ACX3057 10.5mm ID Ring Crimp Terminal Blue Vinyl 1.5 to 2.5mm² Double Crimp M10 Stud Pack of 100
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. Blue colour coding indicates the 1.5 to 2.5mm² cable range. The 10.5mm ID suits M10 bolts and studs, completing the M6/M8/M10 blue ring terminal series alongside the ACX3055 and ACX3056. Covered by a one year warranty.
Product overview
The ACX3057 completes the blue (1.5 to 2.5mm²) ring terminal series in the OEX range, providing the M10 stud option alongside the ACX3055 (6.3mm ID, M6) and ACX3056 (8.4mm ID, M8). The 10.5mm internal diameter suits M10 bolts and studs (10mm nominal diameter). Ring terminals are the preferred choice for battery connections, chassis earth points and other permanent connections where accidental disconnection would be problematic, as the ring loop requires the fastener to be removed for disconnection.
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 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), and 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 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.
