OEX ACX0032 Red Stud Single Terminal with Grooved Brass Contact Post and Glass Filled Nylon Base
The OEX ACX0032 is a heavy duty single stud battery terminal designed to provide a secure, accessible positive connection point for automotive, marine, 4WD, caravan, RV and industrial vehicle applications. It features a 28.8mm grooved brass contact post, two 3/8 16 thread brass stud terminals with a 20.6mm diameter stud, a brass hex nut and lock washer, a glass filled nylon base, and a red cap for positive terminal identification. Supplied individually with a one year warranty.
Product overview
Conventional battery clamp terminals connect directly to the battery post and offer limited connection points for accessories and auxiliary circuits. The ACX0032 provides a panel mountable or surface mountable positive connection point that can be positioned at a more accessible location, making it well suited to 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 point.
The glass filled nylon base provides significantly greater rigidity, impact resistance and thermal stability compared to standard nylon, resisting deformation and cracking in high temperature environments including engine bays and underbonnet electrical panels. The red cap provides immediate identification as the positive terminal. The ACX0032 can be used individually as a standalone positive terminal or paired with a matching black negative terminal to create a complete colour coded battery terminal set. Manufactured under ISO 9001 quality management certification with in house product testing at OEX's Brisbane facility.
Features and benefits
Grooved brass contact post for reliable low resistance connection: The 28.8mm grooved brass contact post provides excellent conductivity and a secure mechanical engagement with cable lugs. The grooved profile helps prevent lug rotation during tightening, maintaining correct alignment and consistent contact pressure.
Two 3/8 16 thread brass stud terminals for multiple connections: Dual stud terminals allow multiple cables and accessories to be connected at the same terminal point, covering main battery cables alongside accessory feeds, fuse block inputs and auxiliary circuit leads without requiring a separate distribution block.
20.6mm diameter stud with brass hex nut and lock washer: The substantial 20.6mm stud diameter provides a large, robust connection platform. The brass hex nut and lock washer combination ensures connections remain secure under vibration, mechanical shock and thermal cycling.
Relocatable to more accessible locations: The ACX0032 can be positioned where it is most convenient, including 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 resists deformation and cracking in high temperature environments, outperforming standard nylon bases across engine bays, battery compartments and underbonnet electrical panels.
Red cap for positive terminal identification: The red cap provides instant positive polarity identification, reducing wiring errors and meeting standard colour coding conventions 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 with a black negative terminal to create a complete, professional colour coded battery terminal solution.
ISO 9001 certified manufacturing: Produced under ISO 9001 quality management certification with in house testing at OEX's Brisbane facility, ensuring consistent quality and long term reliability.

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 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 technically be used on the negative side, but standard practice is to use 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 stacked and connected at the terminal. The practical number of lugs will depend 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 fit the red cap 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 for use inside or outside the vehicle, making it suited to internal battery box installations, boot mounted battery setups and under seat auxiliary battery locations as well as external engine bay and underbonnet applications. Ensure adequate ventilation if mounting near batteries that may off gas during charging.
