Built from 18-8 stainless steel with a bright, uncoated finish, this fastener resists corrosion in both indoor and outdoor service environments. The screw measures 5\/16-18 thread size with a 3\/4-inch length measured under the head. It uses a pin-in hex socket drive, which requires a compatible tamper-resistant bit for installation. The Unified National Coarse (UNC) thread form ensures broad compatibility with standard threaded holes and nuts in inch-based assemblies.\u003c\/p\u003e\n\u003cp\u003eThis fastener suits residential and light commercial applications where corrosion resistance and a low-profile head are required. The button head style sits flush and streamlined against mating surfaces, making it a common choice for equipment panels, access covers, and structural assemblies in HVAC units, electrical enclosures, and plumbing fixtures. Sold in multiples of 5 per order with a package quantity of 1.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e18-8 stainless steel construction for corrosion resistance in wet and outdoor environments\u003c\/li\u003e\n  \u003cli\u003eButton head profile provides a low-profile, clean appearance on finished surfaces\u003c\/li\u003e\n  \u003cli\u003ePin-in hex socket drive deters unauthorized removal and requires a tamper-resistant bit\u003c\/li\u003e\n  \u003cli\u003e5\/16-18 UNC thread standard ensures compatibility with standard inch-system threaded components\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish maintains dimensional accuracy without coating buildup on threads\u003c\/li\u003e\n  \u003cli\u003eLength measured under head at 3\/4 inch for precise fitment in standard applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct fastener for use in standard 5\/16-18 UNC threaded assemblies across HVAC equipment, electrical enclosures, and plumbing hardware.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified tradesperson using a pin-in hex socket bit sized for 5\/16-inch fasteners. Always de-energize electrical equipment and shut off fluid supply lines before replacing fasteners on live systems. Do not overtighten stainless steel fasteners, as galling can occur without proper lubrication or anti-seize compound. Follow applicable NEC, IPC, or IFGC guidelines for fastener use in code-regulated assemblies.\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC (Unified National Coarse)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 3\/4 inches (measured under head)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Button\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Pin-In Hex Socket\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: 18-8 Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright \/ Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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: 5\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: R88444363\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51690041311538,"sku":"R88444363","price":893.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/808bf8d8656043aae46181564504548e.jpg?v=1788266087","url":"https:\/\/voomisupply.com\/products\/value-collection-r88444363-button-head-screw-5-16-18","provider":"Voomi Supply","version":"1.0","type":"link"}
