It features a 5\/16-18 UNC thread with a 3\/4-inch length under the head and is fully threaded from tip to head. The drive is a 1\/4-inch hex socket, requiring a standard hex key or Allen driver. Constructed from 18-8 stainless steel with a bright, uncoated finish, it resists corrosion in wet or mildly corrosive environments. This fastener meets ASME B18.3 and ASTM F837 standards, making it suitable for professional mechanical and industrial service work.\u003c\/p\u003e\n\u003cp\u003eThis screw is used in a wide range of trade and industrial applications where a flush or recessed drive is needed in tight spaces. Common install scenarios include HVAC equipment assemblies, pump and motor mounting, plumbing fixtures, electrical enclosures, and general mechanical equipment. The 5\/16-18 UNC thread is a widely specified coarse thread in both OEM and field-service contexts. The stainless steel construction makes it a practical choice in environments where carbon steel hardware would corrode, including outdoor, marine-adjacent, or high-humidity conditions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC fully threaded coarse-thread fastener\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch length under head for precise fitment in standard applications\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch hex socket drive for use with standard Allen keys or hex bit drivers\u003c\/li\u003e\n  \u003cli\u003e18-8 stainless steel construction with bright, uncoated finish for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.3 and ASTM F837 dimensional and material standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or stock fastener for applications requiring a 5\/16-18 UNC hex socket cap screw with 3\/4-inch length under head per ASME B18.3 and ASTM F837 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by mechanical technicians, millwrights, HVAC service professionals, or plumbers as part of equipment assembly or field repair. Always de-energize and lock out electrical equipment before replacing fasteners in or near live assemblies. Use a properly sized 1\/4-inch hex key or driver to avoid rounding the socket. Do not mix stainless steel fasteners with dissimilar metals in applications where galvanic corrosion is a concern.\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 Under Head\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Fully Threaded\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: 1\/4 inches\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\u003eFastener Standard\u003c\/strong\u003e: ASME B18.3, ASTM F837\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: HOLO-KROME\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 78076\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51750590644530,"sku":"78076","price":2453.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0c9a2a0009891924a2ca223b5da382b3_09d4c5d3-f07b-4b39-8757-f80365860127.jpg?v=1788917087","url":"https:\/\/voomisupply.com\/products\/holo-krome-78076-hex-socket-cap-screw-5-16-18-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
