A missing, corroded, or damaged fastener compromises the integrity of the drain cover — a critical safety component. Replacing with the correct OEM fastener ensures the cover remains properly seated and meets the drain assembly's design specifications. Match the part number stamped or labeled on your existing hardware before ordering.\u003c\/p\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\n\u003ctable style=\"width: 100%; border-collapse: collapse; margin: 20px 0; border: 1px solid #ccc;\"\u003e\n  \u003ctr style=\"background-color: #f8f9fa;\"\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003ePentair Part Number\u003c\/strong\u003e\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e552539\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003eScrew Size\u003c\/strong\u003e\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e#8 x 1-1\/4\"\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f8f9fa;\"\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003eMaterial\u003c\/strong\u003e\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003eNitronic® 60 Stainless Steel\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003eApplication\u003c\/strong\u003e\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003eDual Port Main Drain\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f8f9fa;\"\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003eQuantity Included\u003c\/strong\u003e\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003eEach\u003c\/td\u003e\n  \u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003ePro Tip\u003c\/h3\u003e\n\n\u003cp\u003eMain drain cover screws are a commonly overlooked service item. When inspecting or replacing a drain cover, check all fasteners — corroded or missing screws on a main drain cover are a safety concern and should be addressed immediately. Nitronic® 60 stainless is specified for its superior galling resistance compared to standard 316 stainless, making it well suited for submerged, threaded fastener applications. Verify the screw count required for your specific drain model before ordering — most dual-port drain covers require more than one screw per assembly.\u003c\/p\u003e\n\n\u003c!-- wft:processed:manual:2026-04-04 --\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":53960096743699,"sku":"552539","price":4.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/0687\/5411\/files\/pentair-dual-port-main-drain-screw-8-x-1-1-4-nitronic-60-stainless-steel-552539-3.webp?v=1776952449","url":"https:\/\/poolaroo.com\/products\/pentairwaterpoolandspainc_552539","provider":"Poolaroo","version":"1.0","type":"link"}
