It measures 1.5 inches overall length with full threading under the head in a Unified National Coarse (UNC) thread form. The flat head profile sits flush with or below the mating surface when countersunk, making it a standard choice in panel assemblies, equipment enclosures, and structural fastening applications. Grade 316 stainless steel provides elevated corrosion resistance compared to Grade 304, particularly in chloride-rich or marine-adjacent environments. This fastener is installed by HVAC technicians, plumbers, electricians, and general trade professionals wherever a corrosion-resistant, flush-mount threaded fastener is required.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for light-to-medium duty fastening in both residential and commercial trade applications. Its 1\/4-20 UNC thread is one of the most common inch-series thread sizes in the trade, compatible with standard 1\/4-20 tapped holes, hex nuts, and insert hardware. Typical use cases include mounting control panels, electrical enclosures, equipment covers, and structural brackets where flush fastener seating is needed. The Grade 316 alloy makes it appropriate for wet or corrosive environments such as pool equipment enclosures, outdoor condensing unit panels, and marine-rated installations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 316 stainless steel construction for superior corrosion resistance in chloride and moisture-heavy environments\u003c\/li\u003e\n  \u003cli\u003e1\/4-20 UNC thread form for compatibility with widely available nuts, taps, and threaded inserts\u003c\/li\u003e\n  \u003cli\u003eFlat head profile designed for countersunk, flush-mount installations\u003c\/li\u003e\n  \u003cli\u003ePhillips drive for use with standard Phillips screwdrivers and bits\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — no surface treatment that could mask thread fit or add dimensional variation\u003c\/li\u003e\n  \u003cli\u003e1.5-inch overall length with full threading under the head\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/4-20 UNC inch-series machine screw for use in any application requiring a countersunk flat head fastener in that thread size and length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a properly prepared countersunk or counterbored hole sized for a 1\/4-20 flat head screw. Use a matching Phillips screwdriver or power bit to avoid cam-out and head damage — do not overtighten, as stainless steel fasteners are susceptible to galling when threads are driven dry or at excessive speed. A thread lubricant or anti-seize compound rated for stainless steel is recommended in high-torque or frequent-removal applications. Power down or de-energize any electrical equipment before fastening hardware to live panels or enclosures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Phillips\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Form\u003c\/strong\u003e: UNC (Unified National Coarse)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 316\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright \/ Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWasher Style\u003c\/strong\u003e: Without Washer\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.008 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161504\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: W57792PS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692808470834,"sku":"W57792PS","price":1132.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/44a8ce00820d389bbda1a0b72c5832dc.jpg?v=1788303238","url":"https:\/\/voomisupply.com\/products\/value-collection-w57792ps-1-4-20-x-1-5-in-flat-head-screw","provider":"Voomi Supply","version":"1.0","type":"link"}
