Manufactured from alloy steel with a black oxide finish, this fastener measures 11 inches in length under the head and accepts a 3\/8-inch hex drive. The 1\/2-13 UNC thread form is a coarse-thread standard widely used in general mechanical assembly. The partial threading leaves a smooth shank section that helps resist shear loads in fitted joints. Installers working in maintenance, fabrication, or machine assembly will find this a direct-fit choice for applications requiring a recessed-drive, high-torque fastener.\u003c\/p\u003e\u003cp\u003eThis screw is suited for heavy-duty bolted assemblies in manufacturing equipment, structural fixtures, and machine frames where a coarse-thread 1\/2-inch fastener with an extended 11-inch grip length is specified. The black oxide coating provides mild corrosion resistance and reduces galling during installation. The 3\/8-inch internal hex drive allows use of standard hex keys and socket drive tools. This size is common in industrial maintenance and OEM equipment assembly environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/2-13 UNC coarse-thread specification for broad tooling and hardware compatibility\u003c\/li\u003e\n\u003cli\u003e11-inch length under head accommodates deep-reach and through-bolt applications\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction provides high tensile and shear strength\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish offers mild corrosion resistance and reduces light surface oxidation\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank resists shear forces in close-tolerance assemblies\u003c\/li\u003e\n\u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM A574 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 1\/2-13 UNC hex socket cap screw suitable for use in any application requiring an ASME\/ANSI B18.3 or ASTM A574 compliant fastener of this thread size and length.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified mechanic or millwright using a calibrated torque wrench and a correctly sized 3\/8-inch hex key or socket bit. Clean and inspect threaded holes before installation to ensure proper thread engagement. Apply thread lubricant or anti-seize compound only if specified by the equipment manufacturer, as this affects torque values. Do not exceed the rated torque for alloy steel fasteners of this grade and size.\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: 11 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: 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: 0.59 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: 581565PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51712634487090,"sku":"581565PR","price":1986.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/656180cf4c3593a329629d8d062712d7.jpg?v=1788487142","url":"https:\/\/voomisupply.com\/products\/value-collection-581565pr-hex-socket-cap-screw-1-2-13-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
