Manufactured from alloy steel with a black oxide finish, this screw delivers high tensile strength and moderate corrosion resistance. It measures 1-3\/4 inches in length under the head and is driven with a 3\/8-inch hex key. The fully threaded shank engages the entire fastener length, maximizing thread engagement in through-hole and tapped-hole assemblies. It conforms to ASME\/ANSI B18.3 and ASTM A574 standards, making it a recognized specification fastener for structural and mechanical assembly work.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for machinery assembly, structural steel connections, equipment mounting, and general mechanical fabrication where a recessed hex drive is required. The 1\/2-13 UNC thread form is a coarse-thread standard widely used in steel-to-steel and steel-to-aluminum assemblies across manufacturing, HVAC equipment framing, plumbing equipment supports, and electrical enclosure fabrication. The black oxide coating reduces galling and provides a low-reflectance finish appropriate for exposed mechanical components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-13 UNC coarse-thread form for broad compatibility with standard tapped holes\u003c\/li\u003e\n  \u003cli\u003eFully threaded shank for maximum thread engagement over the full 1-3\/4 inch length under head\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch hex socket drive for use with standard Allen keys and hex bit drivers\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 high-strength cap screw requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish reduces surface friction and provides mild corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME\/ANSI B18.3 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/2-13 UNC hex socket cap screw per ASME\/ANSI B18.3 and ASTM A574, compatible with any tapped or through-hole assembly using a 1\/2-13 coarse-thread specification.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a 3\/8-inch hex key or Allen-type driver; use of a calibrated torque wrench is recommended to achieve proper clamp load without overstressing the fastener. Ensure mating threads are clean, free of debris, and properly tapped to 1\/2-13 UNC specification before installation. De-energize, lock out, and tag out any equipment before fastener service on live machinery per applicable OSHA lockout\/tagout procedures. Do not exceed the rated proof load for this fastener class.\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: 1-3\/4 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: Fully 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: 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\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 33665\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51717817368882,"sku":"33665","price":45.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a4dcb89b265e2588b5c65b309110637d.jpg?v=1788546066","url":"https:\/\/voomisupply.com\/products\/value-collection-33665-hex-socket-cap-screw-1-2-13-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
