It features a 1\/2-13 UNC thread and a 14-inch length under head, making it suited for deep-reach clamping and through-bolt assemblies. The fastener is machined from alloy steel and finished with a black oxide coating that provides mild corrosion resistance and a clean surface for assembly. It is driven with a 3\/8-inch hex key and meets ASME\/ANSI B18.3 and ASTM A574 standards, confirming its suitability for demanding load-bearing installations.\u003c\/p\u003e\u003cp\u003eThis cap screw is used in manufacturing, maintenance, and fabrication environments where high tensile strength and precision threading are required. The 1\/2-13 UNC coarse thread is common in general industrial and mechanical assembly, and the 14-inch under-head length accommodates thick material stacks or long-span clamping applications. Machinists, millwrights, and industrial maintenance technicians typically specify this fastener for equipment assembly and structural fixturing.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/2-13 UNC coarse thread for reliable engagement in standard tapped holes\u003c\/li\u003e\n\u003cli\u003e14-inch length under head for deep-reach and thick-material installations\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank provides a smooth bearing surface for shear-load applications\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction meets ASTM A574 high-strength fastener requirements\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish offers mild corrosion resistance and reduced light reflection\u003c\/li\u003e\n\u003cli\u003e3\/8-inch hex drive for use with standard hex keys and socket drivers\u003c\/li\u003e\n\u003cli\u003eConforms to ASME\/ANSI B18.3 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard-dimension replacement or new-installation fastener for any application requiring a 1\/2-13 UNC partially threaded hex socket cap screw conforming to ASME\/ANSI B18.3 and ASTM A574.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist, millwright, or maintenance technician using a calibrated torque wrench and the appropriate 3\/8-inch hex key or socket driver. Always verify that the mating tapped hole thread form and depth are compatible with 1\/2-13 UNC before installation. De-energize and lock out all equipment before fastening into assemblies on powered machinery. Do not exceed the recommended installation torque for the alloy steel grade and joint material being used.\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: 14 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially Threaded\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\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: 0.01 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: 581569PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694882619698,"sku":"581569PR","price":2906.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/de0893b133aacf5eda457def3178bc5e.jpg?v=1788329381","url":"https:\/\/voomisupply.com\/products\/value-collection-581569pr-hex-socket-cap-screw-1-2-13-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
