This screw features a 3\/8-16 UNC thread, a 3-inch length under head, and a 5\/16-inch hex drive. It is manufactured from alloy steel and finished with an Armor Coat coating for added surface protection. The partial threading design allows for precise clamping and is well-suited for bolted joint applications in mechanical assemblies. Installation is performed using a 5\/16-inch hex key or Allen driver and conforms to ASME B18.3 dimensional standards.\u003c\/p\u003e\n\u003cp\u003eThis screw is used in general industrial, mechanical, and trade assembly applications where a socket-drive fastener is required. It is appropriate for residential and commercial maintenance work, equipment fabrication, and structural fastening tasks. The 3\/8-16 UNC coarse thread pitch is a common standard size used across a wide range of metal fabrication, HVAC equipment mounting, plumbing fixture assembly, and general mechanical work. Installers in multiple trades will encounter this fastener size in field service and repair scenarios.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-16 UNC coarse thread for broad compatibility with standard tapped holes\u003c\/li\u003e\n  \u003cli\u003e3-inch length under head for deep grip and solid clamping force\u003c\/li\u003e\n  \u003cli\u003e5\/16-inch hex socket drive for use with standard Allen keys or hex bit drivers\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank for accurate joint alignment and clamping\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction for high tensile strength in demanding applications\u003c\/li\u003e\n  \u003cli\u003eArmor Coat finish provides corrosion resistance in exposed or harsh environments\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.3 dimensional standard\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard ASME B18.3 hex socket cap screw for use in any application requiring a 3\/8-16 UNC partially threaded fastener with a 5\/16-inch hex drive.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a 5\/16-inch hex key or socket bit driver. Ensure the mating tapped hole is clean and free of debris before driving the fastener. Do not exceed the torque rating of the mating material, and avoid over-torquing, which can strip threads or damage the workpiece. This fastener should be installed by qualified personnel familiar with standard mechanical assembly practices.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3 inches\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: 5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Armor Coat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME B18.3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: ARMOR COAT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: UST235964\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ARMOR COAT","offers":[{"title":"Default Title","offer_id":67906778267954,"sku":"UST235964","price":799.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1b713819eaa4c48166b78fa747a38153_da00c371-694a-483e-92dd-12ef60ef7c1a.jpg?v=1791171395","url":"https:\/\/voomisupply.com\/products\/armor-coat-ust235964-hex-socket-cap-screw-3-8-16-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
