Sized at 5\/16-18 UNC with a 3\/4-inch length under head, this fastener is fully threaded and driven by a 1\/4-inch hex key. It is manufactured from alloy steel and finished with a black oxide coating, which provides moderate corrosion resistance and reduces light reflection. This screw meets ASME\/ANSI B18.3 and ASTM A574 standards, making it suitable for structural and mechanical assemblies across industrial, HVAC, and general trade applications.\u003c\/p\u003e\u003cp\u003eThis fastener is used in residential and commercial mechanical assemblies where a low-profile socket drive head is required. Typical applications include equipment panels, mounting brackets, machinery frames, and HVAC unit components. The 5\/16-18 UNC thread form is a standard coarse-thread specification, compatible with tapped holes and nuts of the same designation. Installers in HVAC, plumbing, electrical, and general mechanical trades commonly use this screw when access space limits the use of hex head or Torx fasteners.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5\/16-18 UNC coarse thread for broad compatibility with standard tapped holes and hardware\u003c\/li\u003e\n\u003cli\u003e3\/4-inch length under head, fully threaded for maximum thread engagement\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\u003eAlloy steel construction meets ASTM A574 high-strength fastener requirements\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish provides mild corrosion resistance and a non-reflective surface\u003c\/li\u003e\n\u003cli\u003eConforms to ASME\/ANSI B18.3 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 5\/16-18 UNC hex socket cap screw for use in any application requiring an ASME\/ANSI B18.3-compliant fastener with a 1\/4-inch hex drive.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a 1\/4-inch hex key or Allen bit driver. Ensure the mating tapped hole or nut is clean and free of debris before driving. Do not exceed the rated torque range for 5\/16-18 alloy steel fasteners as specified by the applicable mechanical or equipment code. Black oxide finish is not a substitute for a rust-inhibiting coating in wet or outdoor environments without additional protection.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: Alloy Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME\/ANSI B18.3 and ASTM A574\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: -33617-1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51695667675442,"sku":"-33617-1","price":21.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/deea60022a37b096b92f445f2a3a615e.jpg?v=1788337274","url":"https:\/\/voomisupply.com\/products\/value-collection-33617-1-hex-socket-cap-screw-5-16-18","provider":"Voomi Supply","version":"1.0","type":"link"}
