Built from alloy steel with an Armor Coat finish for corrosion resistance, this screw features a 1\/2-13 UNC thread size and measures 4.5 inches in length under the head. It is partially threaded and driven with a 3\/8-inch hex drive. Manufactured to ASME B18.3 standards, it is suited for structural and equipment assembly work where a reliable, torque-capable socket-head fastener is required. Weighing 0.28 pounds, it is well-suited for use in demanding environments where finish durability matters.\u003c\/p\u003e\u003cp\u003eThis screw is appropriate for use in commercial and industrial settings where alloy steel fasteners conforming to ASME B18.3 are specified. Typical applications include machinery assembly, structural bracketing, equipment mounting, and other bolted joint configurations where a hex socket drive is preferred for torque control and flush or recessed installation. The partial threading allows for secure clamping force across thicker material stacks, making it a practical choice for heavy-duty mechanical assemblies handled by millwrights, pipefitters, electricians, and general maintenance trades.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/2-13 UNC thread size for common industrial and mechanical applications\u003c\/li\u003e\n\u003cli\u003e4.5-inch length under head with partial threading for strong clamping in thick material\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction for high tensile strength and durability\u003c\/li\u003e\n\u003cli\u003eArmor Coat finish provides corrosion resistance in demanding environments\u003c\/li\u003e\n\u003cli\u003e3\/8-inch hex socket drive compatible with standard hex keys and socket tools\u003c\/li\u003e\n\u003cli\u003eManufactured to ASME B18.3 dimensional and tolerance standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard hex socket cap screw for mechanical and industrial bolted joint assemblies requiring 1\/2-13 UNC thread specifications per ASME B18.3.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by qualified trade personnel using a calibrated torque wrench and the appropriate 3\/8-inch hex key or socket bit. De-energize and lock out any equipment before servicing fastened assemblies per applicable OSHA and facility safety procedures. Do not exceed the fastener's rated torque specification as determined by your engineering reference or applicable mechanical code. Inspect threads for damage before installation and ensure mating threads are clean and free of debris.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 4.5 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: 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: 0.28 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: ARMOR COAT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: UST236003\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ARMOR COAT","offers":[{"title":"Default Title","offer_id":67907058303282,"sku":"UST236003","price":2071.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1b713819eaa4c48166b78fa747a38153_2254674a-fef7-497f-af6b-5f6b57939769.jpg?v=1791173932","url":"https:\/\/voomisupply.com\/products\/armor-coat-ust236003-hex-socket-cap-screw-1-2-13-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
