A 3\/8\"-24 fine-thread hex nut in marine-grade stainless steel, it is used where the Mercury or MerCruiser parts diagram specifically calls for this number. The fine-thread (24 TPI) specification is an important detail — it is not interchangeable with the more common 3\/8\"-16 coarse-thread nut, and substituting the wrong thread pitch will damage the mating fastener or fail to clamp the assembly correctly.\u003c\/p\u003e\n\n\u003ch2\u003ePart Details\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 11-82671013\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBase Number:\u003c\/strong\u003e 82671013\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size:\u003c\/strong\u003e 3\/8\"-24 (fine thread, 24 TPI)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Stainless steel (marine-grade corrosion resistance)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Hex nut\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Genuine Mercury Marine OEM fastener\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCompatible Applications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eUse where the Mercury, MerCruiser, or Quicksilver parts diagram specifically calls for part number 11-82671013 or 82671013\u003c\/li\u003e\n\u003cli\u003eConfirm fitment by engine or drive serial number, assembly location, and current Mercury parts diagram before ordering\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003eAlways confirm by part number and diagram position.

They are not interchangeable. Installing the wrong thread pitch will cross-thread and damage the mating fastener. Always confirm the thread pitch before ordering.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Why use stainless steel instead of plated steel in marine applications?\u003c\/strong\u003e\u003cbr\u003eA: Stainless steel offers significantly better corrosion resistance in saltwater and high-humidity marine environments. Mercury specifies stainless hardware at locations where corrosion resistance is a priority — particularly on external or exposed assemblies.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can I use anti-seize on stainless nuts?\u003c\/strong\u003e\u003cbr\u003eA: Yes — and it is recommended for stainless-on-stainless thread interfaces. Stainless steel is prone to galling (thread welding under friction), which can make the nut impossible to remove without damage. Anti-seize prevents this and makes future service much easier.\u003c\/p\u003e\n\n\u003ch2\u003eParts Desk Insights\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eBest use case:\u003c\/strong\u003e This nut is the right call when the parts diagram specifically calls for 11-82671013 and a stainless, fine-thread replacement is needed at that location. The 3\/8\"-24 fine-thread spec makes it application-specific — it’s not a general-purpose nut. It’s a low-cost part worth ordering ahead of any service that involves disassembling the assembly it belongs to, rather than discovering it’s missing or damaged mid-job.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCommon issues:\u003c\/strong\u003e The most frequent problem is confusing 3\/8\"-24 fine thread with the more common 3\/8\"-16 coarse thread. They look nearly identical but are not interchangeable — installing the wrong pitch will damage the mating stud or bolt. The second common issue is galling during installation on stainless-on-stainless interfaces. Using anti-seize at assembly prevents this and makes future removal straightforward.\u003c\/p\u003e","brand":"MERC","offers":[{"title":"Default Title","offer_id":43563854463012,"sku":"34932","price":3.9,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/b2b82c75-6515-42ff-a72a-584b8fb06786.png?v=1787267559","url":"https:\/\/marisolmarine.com\/products\/merc-171","provider":"Marisol Marine Company","version":"1.0","type":"link"}
