That unthreaded shoulder lets a moving part turn or pivot freely around the screw, rather than binding against threads the way a standard machine screw would, which is why this style is used at pivot and latch points on filter head hardware.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFit and compatibility\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe ECX4236 is sized for the Hayward Perflex EC50C90 series Extended-Cycle DE filter.
