OEX ACX0021 Solid Brass Side Entry Negative Battery Terminal Full Barrel 0–00 B&S Pack of 5 The OEX ACX0021 is a solid brass side entry full barrel negative battery terminal for standard battery posts. Compatible with 0 to 00 B&S cable (50.3 to 65.8mm²) with crimp or solder termination, it is supplied in a pack of 5 with a one-year warranty. Product overview The ACX0021 is designed for high-current negative main lead applications using heavy-gauge cable in the 0 to 00 B&S range. At this cable size, a full barrel side entry terminal is the appropriate format the cable enters from the side of the terminal barrel and is secured by crimping or soldering, providing a robust mechanical and electrical connection suited to the sustained current loads these cables are used for. Solid brass construction ensures corrosion resistance and reliable conductivity in demanding automotive, marine and 4WD environments. The side entry design suits installations where cable routing approaches the battery post from the side rather than the end, offering a different geometry to the end entry ACX0002. The pack of 5 suits workshop and trade use. Features and benefits Side entry full barrel type: Cable enters from the side of the full barrel, suited to installations where cable routing approaches the battery from a lateral direction.

No. The ACX0021 is a negative-only terminal designed for standard negative battery posts. Contact us for a compatible positive terminal option in the OEX range. What cable sizes does the ACX0021 accept? The ACX0021 accepts 0 B&S to 00 B&S cable, equivalent to 50.3mm² to 65.8mm². This covers the heaviest common main lead cable sizes used in high-current automotive, marine and 4WD applications. What is a full barrel side entry terminal? A full barrel terminal encloses the cable conductor completely within a cylindrical barrel, providing maximum contact area for the cable. Side entry means the cable is inserted from the side of the barrel rather than the end. This design is common for heavy-gauge cables where a crimp or solder connection through the full barrel length provides the strongest and most reliable joint. Can I use this terminal with a crimping tool or do I need to solder? The ACX0021 accepts both crimp and solder termination. A heavy-duty cable crimping tool suitable for 0–00 B&S cables is required for crimping, or the terminal can be soldered using appropriate equipment and solder. Either method provides a reliable connection when carried out correctly. How does the ACX0021 differ from the ACX0002? The ACX0002 is an end entry saddle bolt terminal for 6–1 B&S cable. The ACX0021 is a side entry full barrel terminal for the heavier 0–00 B&S range, using crimp or solder termination rather than a saddle bolt. Select the correct terminal based on your cable size and preferred termination method.
