It features an 82-degree flat head profile and a 3\/16-inch hex socket drive, allowing installation with a standard hex key. Sized at 5\/16-18 x 3\/4 inches overall length and fully threaded, this screw is machined from alloy steel and finished with a black oxide coating that provides mild corrosion resistance and a low-reflectance appearance. It conforms to ASME\/ANSI B18.3 and ASTM F835 standards. Machinists, millwrights, and maintenance technicians are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThis fastener is suited for applications where a screw head must sit flush with or below the mating surface. Common uses include machine frames, tool fixtures, equipment enclosures, and structural assemblies that require a clean, snag-free surface. The UNC 5\/16-18 thread pitch is one of the most common inch-series coarse thread sizes, making this screw broadly compatible with standard tapped holes in steel, aluminum, and similar materials. It is sold in a minimum order quantity of 100 pieces per order, with a package quantity of 1.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e82-degree flat head seats flush in standard countersunk holes per ASME\/ANSI B18.3\u003c\/li\u003e\n  \u003cli\u003e3\/16-inch hex socket drive for precise torque application with a hex key or hex bit driver\u003c\/li\u003e\n  \u003cli\u003eFully threaded 3\/4-inch overall length for maximum thread engagement in thinner stock\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction provides high tensile strength suitable for load-bearing fastening\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish reduces light reflection and offers light surface protection against corrosion\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME\/ANSI B18.3 and ASTM F835 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for standard UNC 5\/16-18 tapped holes in metal assemblies requiring a flush or countersunk fastening point.

Ensure the countersink angle in the mating part matches the 82-degree flat head geometry before installation. De-energize or lock out any powered equipment before performing fastener work on live machinery per applicable safety protocols. Do not substitute this fastener in applications requiring metric thread standards or a different head angle.\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\u003eLength\u003c\/strong\u003e: 3\/4 inches (overall)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: 82-degree Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex Socket\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Fully Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME\/ANSI B18.3, ASTM F835\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: 0.018 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 100\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: 211161P\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692564578610,"sku":"211161P","price":5234.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b13046ab27fc8db6c5138a26fb24c4a6.jpg?v=1788299399","url":"https:\/\/voomisupply.com\/products\/value-collection-211161p-flat-socket-cap-screw-5-16-18","provider":"Voomi Supply","version":"1.0","type":"link"}
