This fastener uses Unified National Coarse (UNC) threading and a countersunk flat head profile, making it suitable for flush-mount installations where a clean surface finish is required. Grade 316 stainless steel provides superior corrosion resistance compared to Grade 304, particularly in chloride-rich or marine environments. Tradespeople and maintenance professionals working in wet, coastal, or chemically exposed environments commonly specify this grade for structural and mechanical fastening applications.\u003c\/p\u003e\n\u003cp\u003eThis screw is used in a wide range of commercial and industrial applications where corrosion resistance and flush-seating are required. Typical installations include panel mounting, equipment enclosures, HVAC components, plumbing fixtures, and marine hardware. The Phillips drive accepts standard Phillips screwdrivers and bits. The 1-inch overall length is also the length under head, making specification straightforward for through-hole and tapped-hole applications. These fasteners are ordered in multiples of 10.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 316 stainless steel for enhanced resistance to corrosion, salt spray, and chemical exposure\u003c\/li\u003e\n  \u003cli\u003eFlat countersunk head profile allows flush or recessed installation in mating surfaces\u003c\/li\u003e\n  \u003cli\u003e1\/4-20 UNC thread for broad compatibility with standard tapped holes and hardware\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish preserves dimensional tolerances and is suitable for food-service or sanitary applications\u003c\/li\u003e\n  \u003cli\u003ePhillips drive accepts common Phillips bits and hand tools\u003c\/li\u003e\n  \u003cli\u003eNo washer required — washer style is without washer\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/4-20 UNC machine screw for use in pre-tapped holes or with 1\/4-20 nuts in mechanical assemblies, equipment panels, and fixtures requiring Grade 316 stainless steel fasteners.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a Phillips screwdriver or appropriate Phillips bit in a power driver set to a controlled torque setting to avoid overdriving the countersunk head. Ensure the mating material is pre-tapped to 1\/4-20 UNC or use a compatible nut and through-hole configuration. When installing into dissimilar metals, be aware of potential galvanic corrosion and use appropriate isolation methods as required by the application. Power down or de-energize any nearby electrical components before working in enclosures or panels.\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 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Flat (Countersunk)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Phillips\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\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: 0.0057 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161504\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\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: W57780PS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51690690838834,"sku":"W57780PS","price":755.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ca0fad2afa7ba14ee2bdb3247d2f1b21.jpg?v=1788274005","url":"https:\/\/voomisupply.com\/products\/value-collection-w57780ps-1-4-20-x-1-in-flat-head-phillips-screw","provider":"Voomi Supply","version":"1.0","type":"link"}
