It features a flat countersunk head profile and a Phillips drive, making it suited for flush-mount fastening applications where the fastener head must sit at or below the surface of the material. The screw meets ASME B18.6.3 and SAE J82 standards, confirming dimensional and mechanical compliance for inch-series machine screws. Overall length is 2-1\/4 inches with length measured from under the head, and the thread specification is 5\/16-18 UNC coarse thread. This fastener is handled and installed by machinists, maintenance technicians, and field service professionals across a wide range of industries.\u003c\/p\u003e\n\u003cp\u003eThis screw is used in general mechanical assembly, equipment maintenance, and industrial fabrication applications where a countersunk flat head is required. The 5\/16-18 coarse thread is one of the most common inch-series thread sizes in North American trade work and is found in machine frames, panel mounting, and structural fastening applications. The zinc finish provides light corrosion resistance suitable for indoor and protected environments. Minimum order quantity is 10 units per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC coarse thread for broad compatibility with standard tapped holes and nuts\u003c\/li\u003e\n  \u003cli\u003eFlat countersunk head sits flush with or below the mating surface\u003c\/li\u003e\n  \u003cli\u003ePhillips drive for fast installation with standard power and hand tools\u003c\/li\u003e\n  \u003cli\u003eSteel construction with zinc finish for light corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.6.3 and SAE J82 dimensional and material standards\u003c\/li\u003e\n  \u003cli\u003eOverall length 2-1\/4 inches, measured as full overall length\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 5\/16-18 tapped holes in steel, aluminum, and other materials where an inch-series flat head Phillips machine screw is specified per ASME B18.6.3.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, maintenance mechanics, or general tradespeople using a Phillips screwdriver or Phillips bit with a power driver. Always verify that the receiving hole is tapped to 5\/16-18 UNC and that the countersink angle matches the flat head profile before installation. De-energize and lock out any equipment before fastener replacement on live machinery. Do not overtorque steel screws into soft base materials such as aluminum without consulting appropriate torque references for the application.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 2-1\/4 inches\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\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: J82\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME B18.6.3, SAE J82\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: 0.04 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: 586767PS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694518632754,"sku":"586767PS","price":1326.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8f5904e3732c3f85f99284e856207332.jpg?v=1788324928","url":"https:\/\/voomisupply.com\/products\/value-collection-586767ps-5-16-18-x-2-1-4-flat-head-phillips-screw","provider":"Voomi Supply","version":"1.0","type":"link"}
