OEX ACX0032 Stud Single Terminal - Red

OEX ACX0032 Stud Single Terminal - Red

Relocate or extend your battery positive connection to a more accessible location with the OEX ACX0032 Stud Single Terminal — featuring a grooved brass contact post 28.8mm long, 20.6mm diameter stud with brass hex nut and lock washer, two 3/8-16 thread brass stud terminals, glass-filled nylon base for strength and heat resistance, red cap for positive rail identification, and flexible installation for use inside or outside the vehicle individually as a positive terminal or in pairs as a complete positive and negative terminal set.

Product Overview

The OEX ACX0032 is a heavy-duty single stud battery terminal designed to provide an accessible, secure, and professional connection point for positive battery circuits in automotive, marine, 4WD, caravan, RV, and industrial vehicle applications. Where conventional battery clamp terminals connect directly to the battery post and offer limited connection points for accessories and auxiliary circuits, the ACX0032 stud terminal provides a panel-mountable or surface-mountable positive connection point that can be positioned at a more accessible location — making it ideal for relocated battery installations, auxiliary battery setups, battery boxes, battery trays, and custom electrical builds where direct battery post access is inconvenient or impractical. The grooved brass contact post delivers reliable, low-resistance electrical contact with cable lugs, while the two 3/8-16 thread brass stud terminals allow multiple cables and accessories to be connected securely at the same terminal point. The brass hex nut and lock washer combination ensures connections remain tight under vibration and thermal cycling common in mobile applications. Glass-filled nylon base construction provides the same superior rigidity, heat resistance, and electrical isolation found across the OEX terminal range — significantly outperforming standard nylon bases in high-temperature environments. The red cap provides immediate identification as the positive terminal, and the ACX0032 can be used individually as a standalone positive terminal or in matched pairs with a black negative terminal to create a complete colour-coded battery terminal pair. Suitable for installation inside or outside the vehicle, the ACX0032 suits battery boxes, engine bays, under-bonnet electrical panels, boot-mounted auxiliary systems, and marine battery compartments. ISO 9001-certified manufacturing and in-house testing at OEX's Brisbane facility ensures consistent quality and long-term reliability.

Features & Benefits

Grooved Brass Contact Post for Reliable Low-Resistance Connection: The 28.8mm long grooved brass contact post provides excellent electrical conductivity and a secure mechanical engagement with cable lugs — the grooved profile helps prevent lug rotation during tightening, maintaining proper alignment and consistent contact pressure for a reliable, low-resistance connection.

Two 3/8-16 Thread Brass Stud Terminals for Multiple Connections: Dual 3/8-16 thread brass stud terminals allow multiple cables and accessories to be connected at the same terminal point — ideal for connecting main battery cables alongside accessory feeds, fuse block inputs, or auxiliary circuit leads without requiring a separate distribution block at the battery terminal.

20.6mm Diameter Stud with Brass Hex Nut and Lock Washer: The substantial 20.6mm stud diameter provides a large, robust connection platform, while the brass hex nut and lock washer combination ensures connections remain secure under vibration, mechanical shock, and thermal cycling common in mobile vehicle applications.

Relocatable to More Accessible Locations: Designed specifically for battery connections at more accessible locations, the ACX0032 enables positive terminal connections to be positioned where they are most convenient — battery boxes, custom panels, bulkheads, and auxiliary battery locations — without compromising connection quality or current capacity.

Glass-Filled Nylon Base for Superior Strength and Heat Resistance: Glass-filled nylon construction provides significantly greater rigidity, impact resistance, and thermal stability compared to standard nylon, resisting deformation and cracking in high-temperature environments including engine bays, battery compartments, and under-bonnet electrical panels.

Red Cap for Positive Terminal Identification: The red protective cap provides instant identification as the positive terminal in any installation, reducing wiring errors and meeting the standard colour-coding convention for positive battery connections across automotive, marine, and industrial applications.

Versatile Installation — Individual or Paired Use: Can be used individually as a standalone positive terminal or in matched pairs — one red positive and one black negative — to create a complete, professional colour-coded battery terminal solution for relocated or auxiliary battery installations.

ISO 9001 Certified Manufacturing: Produced under ISO 9001 quality management certification with in-house product testing at OEX's Brisbane facility, ensuring consistent quality and long-term reliability across automotive, marine, RV, and industrial applications.

Frequently Asked Questions

What is a stud single terminal and when would I use one instead of a standard battery clamp?

A stud single terminal provides a panel-mounted or surface-mounted battery connection point that can be positioned away from the battery post itself — at a more accessible location such as a battery box wall, bulkhead, or custom panel. It is used when direct battery post access is inconvenient or when a clean, dedicated connection point is needed for multiple cables at a relocated battery installation. Unlike a battery clamp that attaches directly to the battery post, the stud terminal is fixed to a surface and cables are connected via cable lugs to the threaded studs.

Can the ACX0032 be used as both a positive and negative terminal?

The ACX0032 is supplied in red, designating it as a positive terminal. A matching black negative variant is available separately. When used in pairs — one red and one black — they form a complete colour-coded positive and negative battery terminal set. The ACX0032 can be used as a negative terminal if required, but standard installation practice uses red for positive and black for negative to maintain clear polarity identification.

How many cables can be connected to the ACX0032 at once?

The ACX0032 features two 3/8-16 thread brass stud terminals, allowing multiple cable lugs to be connected and stacked at the terminal. In practice, the number of lugs depends on the thread engagement length available after accounting for the thickness of each lug. Ensure all connections are torqued firmly and that the combined current draw of all connected circuits is within safe limits for the wire gauges used.

Is the ACX0032 suitable for outdoor and marine installations?

The brass terminal construction and glass-filled nylon base provide good corrosion resistance for outdoor and marine applications. For best long-term performance in marine environments, use tinned copper cable lugs, apply dielectric grease to all contact surfaces before assembly, and ensure the red cap is fitted when the terminal is not in use to protect the contact post from moisture and contamination.

Can the ACX0032 be mounted inside the vehicle cabin?

Yes — the ACX0032 is designed to be used inside or outside the vehicle, making it suitable for internal battery box installations, boot-mounted battery setups, and under-seat auxiliary battery locations as well as external engine bay and under-bonnet applications. Ensure adequate ventilation if mounting near batteries that may off-gas during charging.
