The Honda 90306-413-950 Battery Terminal Nut is a genuine OEM Battery Terminal Nut designed for EX3300 and EX4500 generators. As a factory-original component, this nut is manufactured to Honda's exact specifications, ensuring a secure and properly torqued connection at the battery terminal. Confirm the fitment against your generator's serial number using the compatibility table before ordering — Honda supersedes parts at production breaks, and verifying your unit ensures you receive the correct piece.
Key Features
- Genuine OEM Honda Part — manufactured by Honda to the exact specification of the original, ensuring the correct thread form and dimensional fit for the battery terminal on EX3300 and EX4500 generators
- Direct Drop-In Replacement — replaces the original nut without modification, restoring a firm, properly seated connection at the terminal
- Serial Number Verification Recommended — Honda updates parts at specific production breaks, so check your generator's serial number against the fitment table to confirm this is the right nut for your unit
- Critical Connection Integrity — a loose or damaged terminal nut compromises the electrical connection between the battery and the generator's starting circuit, leading to unreliable starts or intermittent electrical faults
The battery terminal nut secures the cable lug to the generator's battery terminal post, maintaining a tight, low-resistance electrical connection. A properly fastened terminal nut is essential for consistent current flow between the battery and the starter circuit — a loose or corroded nut can cause hard starts, voltage drop, or failure to crank. Replacing a worn or stripped nut with the correct OEM part, such as this one identified by part number 90306-413-950, restores the integrity of that connection and keeps the generator's electrical system functioning as intended.
