It is the genuine part, classed as a pool filter part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhere it belongs\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003ePentair groups this nut with the PacFab FNS fiberglass DE filters in the FNS24, FNS36, FNS48 and FNS60 sizes, and with the PacFab Nautilus and Nautilus Plus DE filters. These are the fasteners that hold a filter under pressure, which is exactly the place not to improvise. Stainless is specified because the hardware sits in a wet, chemically loaded environment for years at a time.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eOrdering\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eFour are called for, so replace the whole set at once. Mixing one new nut with three corroded ones loads the clamp unevenly, and the old ones will be the next thing to fail. Note the thread as Pentair gives it, 5\/16 inch-16, and check it against the stud on your own filter before ordering.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":48634710327508,"sku":"PAC-051-2920","price":12.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_dca2dc9f-ca91-499b-82dc-a66bff75ee3e.gif?v=1788836521","url":"https:\/\/www.activepoolsupply.com\/products\/nut-5-16-16-ss-4-required","provider":"Active Pool Supply","version":"1.0","type":"link"}
