These are not interchangeable — a coarse-thread nut will not engage properly on a fine-thread stud and must never be substituted.

It shows up in several different locations across Mercury and MerCruiser products, so the engine model alone won’t tell you if it’s the right nut. The most common mistake is grabbing a 5\/16-18 coarse-thread nut from a hardware store because it looks identical — it won’t thread onto a fine-thread stud and can damage the stud if forced. Use a thread gauge if you’re not sure what’s on the engine, and always match the diagram position and item number, not just the size.\u003c\/p\u003e","brand":"MERC","offers":[{"title":"Default Title","offer_id":43563860066340,"sku":"45592","price":3.85,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/18fac84b-d412-4b4a-a8ac-2a255b1b609e.png?v=1789440731","url":"https:\/\/marisolmarine.com\/products\/merc-296","provider":"Marisol Marine Company","version":"1.0","type":"link"}
