{"product_id":"screw-1","title":"Hayward SPX1600Z4 Housing Cap Screw","description":"\u003cp\u003eThe Hayward SPX1600Z4 is the housing cap screw used on the Super Pump and Super II and on a number of other Hayward and Jandy Laars products. It is the genuine Hayward part, given as 3\/8-16 x 2.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhere it is used\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eHayward lists it under the Super Pump SP1600, SP1600X, SP2600 and SP2600X, and the Super II SP3000 and SP3000X including the Heldor EZ-Flo. The same fastener is carried under the Max-Flo 1800 and 2800, the Leslie's Hydramax II, the Super Spa SP-3500, an HRP sand filter group and several Jandy Laars Series 2 and Lite heater diagrams. That is a broad list for one screw, so measure the one you are replacing against the 3\/8-16 x 2 size rather than ordering on the model name alone.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eThe practical problem\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThese screws sit in a wet, chlorinated environment for years and then have to come out during a service. Many do not, or they come out with the head chewed. Work them with penetrating oil and time rather than force, because a screw snapped off inside a housing turns a routine job into an extraction. When you do get them out, it is usually worth replacing the whole set: they have all seen the same water and the same heat.\u003c\/p\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":48634971521236,"sku":"HAY-101-2021","price":11.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_dca86055-2c5a-4175-90aa-db9207d15eb5.png?v=1788839218","url":"https:\/\/www.activepoolsupply.com\/products\/screw-1","provider":"Active Pool Supply","version":"1.0","type":"link"}
