Built from alloy steel with an Armor Coat finish for corrosion resistance, this screw features a 1\/2-13 UNC thread size and measures 4 inches in length under the head. It is partially threaded and driven with a 3\/8-inch hex key. The Armor Coat coating provides a durable protective layer suited for environments where standard zinc plating falls short. This fastener meets ASME B18.3 dimensional standards, making it a reliable choice for precision-fit applications where dimensional consistency is required.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is used in a wide range of trade and industrial settings including HVAC equipment mounting, mechanical equipment frames, pumping systems, and structural steel assemblies. The 1\/2-13 UNC coarse thread pattern is well suited for general fastening into steel, aluminum, and cast materials where quick engagement and strong clamping force are needed. Licensed mechanics, millwrights, and field technicians working on commercial and industrial equipment will find this fastener appropriate for standard bolt-pattern assemblies requiring a recessed-drive cap screw.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAlloy steel construction for high tensile strength and durability\u003c\/li\u003e\n  \u003cli\u003eArmor Coat finish provides enhanced corrosion resistance over standard coatings\u003c\/li\u003e\n  \u003cli\u003e1\/2-13 UNC coarse thread for strong thread engagement and fast installation\u003c\/li\u003e\n  \u003cli\u003e4-inch length under head suits deep-reach fastening applications\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank for precise clamping in bolted joints\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.3 dimensional standard for consistent fit and interchangeability\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch hex drive compatible with standard hex keys and socket tooling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit fastener for applications requiring a 1\/2-13 UNC hex socket cap screw with a 4-inch length under head, conforming to ASME B18.3.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic or technician familiar with fastener standards and torque requirements for the specific assembly. De-energize and lock out all powered equipment before accessing fastener locations on machinery. Use the correct 3\/8-inch hex key or socket to avoid rounding the drive recess. Follow the equipment manufacturer's torque specifications for the assembly being serviced, as torque values vary by application and joint design.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 3\/8 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: UST236002\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ARMOR COAT","offers":[{"title":"Default Title","offer_id":67911090602290,"sku":"UST236002","price":1789.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1b713819eaa4c48166b78fa747a38153_0da48796-1e9a-4ab1-b456-f16a1ded2cbc.jpg?v=1791204231","url":"https:\/\/voomisupply.com\/products\/armor-coat-ust236002-hex-socket-cap-screw-1-2-13-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
