It is 1\/4-20 by 1 in. with a Phillips head and, importantly, a left hand thread.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eThe left hand thread\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThis screw loosens clockwise. Pump impellers spin in a direction that would back a normal screw out, so the thread is reversed to keep it tight. Anyone who does not know that ends up cranking the screw harder into the impeller and rounding out the head.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat it holds\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe set screw locks the impeller onto the motor shaft. If it works loose the impeller can spin on the shaft and the pump loses flow, so it is worth fitting a fresh screw whenever the impeller comes off rather than reusing a worn one.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eIt is used across a number of Pentair pumps, including IntelliFlo VS 3050 and VF models and WhisperFlo WF and WFE models.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":48625721835732,"sku":"PUR-101-6175","price":5.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_126d5f4b-4b3e-4fbb-8da4-2e5bf7528cd2.png?v=1788689951","url":"https:\/\/www.activepoolsupply.com\/products\/screw-1-4-20-x-1-left-hand-thread","provider":"Active Pool Supply","version":"1.0","type":"link"}
