Small hardware like this is often overlooked during service — but using the correct OEM screw with the right thread pitch, length, and material is essential for maintaining proper clamping force and corrosion resistance in a marine environment.\u003c\/p\u003e\u003ch2\u003eKey Specifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003ePart Number: \u003cstrong\u003e8M0214921\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eType: Screw\u003c\/li\u003e\n\u003cli\u003eGenuine OEM — not aftermarket\u003c\/li\u003e\n\u003cli\u003eWeight: 0.5 oz\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCommon Applications\u003c\/h2\u003e\u003cp\u003eUse this screw wherever the Mercury or MerCruiser parts diagram specifies part number \u003cstrong\u003e8M0214921\u003c\/strong\u003e. It appears across multiple engine families and drive configurations — always verify against your model's current parts diagram, serial number, and assembly location before ordering.\u003c\/p\u003e\u003ch2\u003eWhen to Replace\u003c\/h2\u003e\u003cp\u003eReplace any time the screw shows signs of corrosion, thread damage, rounding, or deformation, or whenever it is removed from a critical fastened joint during service. Reusing compromised fasteners risks joint failure under load.\u003c\/p\u003e\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\u003cp\u003eCompare thread pitch, length, and diameter against the parts diagram before installation. Follow the Mercury service manual for the correct torque specification, locking compound requirements, and fastener reuse limits for the assembly you're working on.\u003c\/p\u003e\u003ch2\u003eRelated Hardware\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/collections\/fasteners-mounting\"\u003eFasteners \u0026amp; Mounting Hardware\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/collections\/gaskets-seals-o-rings\"\u003eMarine Gaskets, Seals \u0026amp; O-Rings\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eParts Desk Insights\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eBest use case:\u003c\/strong\u003e Direct OEM replacement during engine, drive, or powerhead service where the parts diagram calls for 8M0214921. This is a common service item on MerCruiser sterndrive and Mercury outboard assemblies — always order by the exact part number shown in your diagram. Thread pitch and length matter: a visually similar screw from a hardware store may not meet the material or dimensional spec required for a marine application. If your assembly has been repowered or updated, cross-reference the current diagram to confirm this number hasn't been superseded.\u003c\/p\u003e","brand":"MERC","offers":[{"title":"Default Title","offer_id":43563851415588,"sku":"31700","price":4.33,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/images_c2244513-013f-400c-9aba-fc5c99bf22f9.jpg?v=1786563035","url":"https:\/\/marisolmarine.com\/products\/merc-122","provider":"Marisol Marine Company","version":"1.0","type":"link"}
