The 1\/4-20 thread designation indicates a 0.25-inch nominal diameter with 20 threads per inch on a unified coarse thread form. Overall length is 0.5 inches, measured from the tip to the top of the head. Grade 316 stainless steel provides enhanced corrosion resistance compared to 304-series alloys, making it suitable for wet, chlorinated, or chemically aggressive environments. This screw is installed by mechanics, plumbers, electricians, and maintenance technicians across residential, commercial, and industrial applications.\u003c\/p\u003e\n\u003cp\u003eThis fastener is used where a flush or countersunk fastening point is required. The flat head profile seats into a countersunk hole to sit flush with or below the surface of the mating material. Grade 316 stainless steel is a standard material choice for pool equipment, marine hardware, coastal HVAC enclosures, chemical processing panels, and any service environment where chloride exposure or moisture contact is a concern. Phillips drive is compatible with standard No. 2 Phillips bits and drivers commonly carried by trade professionals.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 316 stainless steel construction for strong chloride and corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e1\/4-20 UNC thread form for compatibility with standard unified coarse threaded inserts and nuts\u003c\/li\u003e\n  \u003cli\u003eFlat head profile designed for countersunk installations requiring a flush surface finish\u003c\/li\u003e\n  \u003cli\u003ePhillips drive accepts standard No. 2 Phillips bits and screwdrivers\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish preserves natural stainless steel surface without added plating\u003c\/li\u003e\n  \u003cli\u003e0.5-inch overall length suitable for light-duty panel, bracket, and enclosure fastening\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/4-20 UNC flat head machine screw for use in any application requiring a countersunk fastener with unified coarse threading and Grade 316 stainless steel material.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a properly countersunk or flat-bottomed clearance hole sized for a 1\/4-20 fastener.
