The 5mm ID suits M5 bolts and studs. Covered by a one year warranty.
Product overview
The ACX3059 is a yellow (4.0 to 6.0mm²) ring terminal suited to M5 bolts and studs, the smallest stud size in the OEX ring terminal range covered at this cable gauge. While the blue ring terminals (ACX3055 to ACX3057) cover the 1.5 to 2.5mm² range across M6, M8 and M10 studs, the ACX3059 serves heavy gauge wiring in the 4.0 to 6.0mm² range on the smaller M5 stud format suited to high-current accessory and auxiliary circuit earth and supply connections where a compact mounting point is used.
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 yellow (4.0 to 6.0mm²) range is recommended. The pack of 100 suits trade workshops.
Features and benefits
5mm ID ring suits M5 bolts and studs: Ring loop placed over M5 fastener before tightening for a bolted connection that cannot pull free.
Cannot pull free when fastened: Ring loop requires the fastener to be removed for disconnection, making ring terminals the preferred choice for permanent circuit connections.
Yellow vinyl insulation: Colour codes the 4.0 to 6.0mm² cable range following the standard automotive terminal convention.
Double crimp design: Separate cable crimp and insulation crimp for a secure electrical connection with strain relief.
Tin plated copper: Reliable conductivity and corrosion resistance for long-term terminal performance.

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 5mm ID ring terminal suit? The 5mm internal diameter suits M5 bolts and studs. For M6 studs use the ACX3055 (6.3mm ID). For M8 studs use the ACX3056 (8.4mm ID). For M10 studs use the ACX3057 (10.5mm ID).
What does the yellow colour indicate? Yellow is the standard colour code for automotive crimp terminals suited to the 4.0 to 6.0mm² 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.
