The flat head profile sits flush with or below the mating surface when installed in a countersunk hole, making it well suited for assemblies where a smooth exterior face is required. The 5\/16-18 thread designation indicates a 5\/16 inch nominal diameter with 18 threads per inch on a Unified National Coarse (UNC) thread form. The bright, uncoated finish retains the natural corrosion resistance of 18-8 stainless steel without any added plating. Mechanical, maintenance, and fabrication tradespeople will encounter this fastener in general industrial and structural assembly work.\u003c\/p\u003e\n\u003cp\u003eThis screw is used in applications requiring a flush-mounted fastener with reliable corrosion resistance. The 18-8 stainless steel construction makes it appropriate for environments with incidental moisture exposure, including light marine, food-processing-adjacent, and outdoor equipment applications. The slotted drive accepts a standard flat-blade screwdriver, which is useful in low-torque or space-constrained situations. Overall length is 3 inches measured from tip to the top of the head, and the length under the head is also 3 inches, consistent with flat head countersunk geometry. This screw ships without a washer and is intended for use in pre-tapped holes or with a standard hex nut.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC thread form for compatibility with standard inch-series tapped holes and nuts\u003c\/li\u003e\n  \u003cli\u003eFlat head profile designed for countersunk holes to produce a flush surface finish\u003c\/li\u003e\n  \u003cli\u003eSlotted drive accepts a flat-blade screwdriver for installation and removal\u003c\/li\u003e\n  \u003cli\u003e18-8 stainless steel construction provides solid corrosion resistance without a coating\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish maintains dimensional accuracy on threads\u003c\/li\u003e\n  \u003cli\u003e3 inch overall length with no washer included — fits direct-to-material installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose inch-series machine screw for use in pre-tapped 5\/16-18 UNC holes or with matching 5\/16-18 hex or coupling nuts across a wide range of light industrial, mechanical, and structural assembly applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by mechanical or maintenance tradespeople using a standard flat-blade screwdriver or appropriate power driver. Ensure the receiving hole is properly countersunk to the correct angle before seating the flat head flush. Verify thread engagement depth is sufficient for the load requirements of the application before torquing. Do not exceed the shear and tensile limitations of 18-8 stainless steel in high-vibration or high-load structural connections without consulting applicable fastener standards.\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: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3 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: Slotted\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: 18-8\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\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: R63060844\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694713471282,"sku":"R63060844","price":702.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/eaaeb51c87b2d9e792b628a9499af88d.jpg?v=1788327589","url":"https:\/\/voomisupply.com\/products\/value-collection-r63060844-5-16-18-x-3-in-flat-slotted-screw","provider":"Voomi Supply","version":"1.0","type":"link"}
