OEX ACX0026 Battery Terminal Marine Stud Type 10mm Negative 5Pce

OEX ACX0026 Solid Brass Marine Stud Type 10mm Negative Battery Terminal One Piece Pack of 5

The OEX ACX0026 is a solid brass one-piece marine stud type negative battery terminal with a 10mm stud and wing nut termination, suited to standard European-style battery posts. Construction and specification are identical to the ACX0025 positive terminal, in the negative polarity. Supplied in a pack of 5 with a one-year warranty.

Product overview

The ACX0026 is the negative companion to the ACX0025 positive terminal, forming a matched positive/negative pair for standard post battery installations. The one-piece brass construction integrates the terminal body and 10mm marine stud as a single component, providing structural rigidity and a consistent electrical connection point without the potential weak spots of jointed or multi-part terminals. The wing nut allows ring terminals, cable lugs and accessories to be connected and released by hand, making it a practical choice for installations where the battery may need to be accessed regularly.

At the negative post, the 10mm stud serves as the main connection point for the negative main lead and provides a secondary connection for chassis ground runs, fuse panels, battery management system negatives and other accessories requiring a negative terminal point. The pack of 5 suits workshop, trade and fleet use, and pairs directly with the ACX0025 to complete a full terminal set.

Features and benefits

Solid brass one-piece construction: The stud and terminal body are formed as a single integrated component, providing structural integrity and a consistent electrical connection over the service life of the terminal.

10mm marine type stud: The 10mm threaded stud accepts ring terminals and accessories with a 10mm hole, providing a reliable negative connection point for the main lead and secondary accessories.

Wing nut termination: The wing nut allows connections to be tightened and released by hand without a spanner, suited to installations where tool access is limited or regular disconnection is required. For permanent high-vibration installations, a tool-tightened bolt connection may provide more secure retention.

Negative polarity: Designated for negative standard battery post installations. Pairs directly with the ACX0025 positive terminal for a complete matched set.

Suits standard European-style battery posts: Compatible with the larger standard battery post diameter used on the majority of Australian automotive, marine and caravan batteries.

Pack of 5: Five terminals per pack suits workshop, trade and fleet use.

One year warranty: Covered by a one-year OEX warranty.

Frequently asked questions

How does the ACX0026 differ from the ACX0025? The ACX0026 and ACX0025 are identical in construction same solid brass one-piece body, 10mm marine stud, wing nut termination, standard post sizing and 5-piece pack. The ACX0026 is the negative terminal and the ACX0025 is the positive. Purchase both for a complete positive/negative terminal pair.

What does the 10mm stud allow me to connect? The 10mm stud accepts ring terminals with a 10mm hole, providing a negative connection point at the battery for the main lead and secondary accessories including chassis ground connections, fuse panels, battery management systems and other equipment requiring a negative terminal connection.

What is a wing nut and when is it the right choice? A wing nut has protruding wings that allow hand-tightening without a spanner. It suits installations where the battery is accessed regularly or tool access is limited. For permanent high-vibration installations, a tool-tightened bolt provides more secure retention.

Is the ACX0026 the correct negative companion for the ACX0025? Yes. The ACX0026 is the designated negative companion to the ACX0025 positive terminal, providing a matched pair for standard post battery installations.

Can I use the ACX0026 on a Japanese-style small post battery? No. The ACX0026 is designed for standard European-style battery posts and will not correctly clamp onto the smaller Japanese-style post. Contact us for Japanese-style post terminal options.
