It accepts a 3\/16-inch hex drive and is partially threaded, making it suited for applications where the unthreaded shank must bear shear loads or allow clearance through a mating part. Constructed from 18-8 stainless steel with a bright, uncoated finish, this fastener resists corrosion in wet or mildly corrosive environments. It conforms to ASME B18.3 and ASTM F837, meeting recognized dimensional and mechanical standards for socket cap screws used in industrial and mechanical assemblies.\u003c\/p\u003e\n\u003cp\u003eThis screw is used in a wide range of mechanical, industrial, and light structural applications where a flush or low-profile fastener head is required. The socket drive allows installation in tight clearances where a conventional hex bolt would be inaccessible. Typical users include maintenance technicians, millwrights, and equipment assemblers working on machinery, brackets, enclosures, and fabricated components. The stainless steel construction suits installations in food service equipment, marine adjacent environments, or any assembly where corrosion resistance is a priority over high tensile strength.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-20 UNC thread for broad compatibility with standard inch-series tapped holes\u003c\/li\u003e\n  \u003cli\u003e2-inch length under head with partial threading, leaving an unthreaded shank section\u003c\/li\u003e\n  \u003cli\u003e3\/16-inch hex socket drive for installation with a standard hex key or Allen driver\u003c\/li\u003e\n  \u003cli\u003e18-8 stainless steel construction provides corrosion resistance without surface coating\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.3 and ASTM F837 dimensional and mechanical standards\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish maintains precise dimensions for close-tolerance applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-service socket cap screw for any application using a 1\/4-20 UNC partially threaded hex socket cap screw per ASME B18.3.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a 3\/16-inch hex key or T-handle driver; verify hole alignment before driving to prevent cross-threading. Ensure the mating tapped hole is clean and free of debris before installation. Apply appropriate thread lubricant or anti-seize if the assembly will be exposed to repeated thermal cycling or moisture. Follow applicable torque guidelines for 1\/4-20 stainless steel fasteners per your engineering specifications or assembly documentation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially 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: 3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel, Grade 18-8\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  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\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: 78070\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51747282288946,"sku":"78070","price":1939.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2cb5197b0880f41177d7e4c6a8dd8990.jpg?v=1788878614","url":"https:\/\/voomisupply.com\/products\/holo-krome-78070-hex-socket-cap-screw-1-4-20-unc-2-in","provider":"Voomi Supply","version":"1.0","type":"link"}
