How Can I Determine the Right Bolt Size for My ATV Battery Installation?

To determine the right bolt size for your ATV battery installation, you need to identify the terminal type and correctly measure the bolt diameter, length, and thread pitch.

  1. Identify terminal type: ATV batteries typically have two types of terminals – SAE (Society of Automotive Engineers) and JIS (Japanese Industrial Standards). SAE terminals usually have a diameter of 5/16 inch, while JIS terminals tend to have a slightly smaller size, approximately 8 mm (0.315 inch).

  2. Measure bolt diameter: Using a caliper or ruler, measure the diameter of the battery terminal hole. For SAE terminals, you will most likely require a bolt with a diameter of 5/16 inch. For JIS terminals, consider using an M8 bolt, which has a diameter of 8 mm.

  3. Measure bolt length: The length of the bolt should be sufficient to secure the terminal without protruding too far. Typically, you want the bolt to extend at least a few threads beyond the terminal. Generally, a length of around 1 inch (25 mm) is adequate for most battery installations.

  4. Check thread pitch: Thread pitch refers to the distance between threads. Standard SAE bolts have a fine thread pitch of 18 threads per inch (TPI). If you use a metric M8 bolt, the standard thread pitch is 1.25 mm. Ensure that the bolt you select matches the thread pitch of your terminal.

  5. Use corrosion-resistant materials: Opt for bolts made from corrosion-resistant materials, such as stainless steel or zinc-plated steel. This choice helps prevent battery terminals from corroding over time, ensuring a reliable electrical connection.

  6. Tighten securely: Once you have the correct bolt size, securely tighten it to ensure a good connection. However, avoid overtightening, as this may damage the battery terminal or bolt.

By following these steps, you can successfully determine the right bolt size for your ATV battery installation, ensuring a safe and effective connection.
