Manufactured from Grade 8 steel with a zinc yellow dichromate finish, it delivers strong corrosion resistance and meets the mechanical property requirements demanded in heavy-duty assemblies. The screw features a 9\/16-12 UNC thread size and a 3-1\/2 inch length under head. It conforms to ASME B18.2.1 and SAE J429 standards, making it a recognized choice for structural, industrial, and mechanical installations where fastener grade traceability matters.\u003c\/p\u003e\n\u003cp\u003eThis hex head cap screw is suited for applications in industrial machinery, structural fabrication, heavy equipment assembly, and general mechanical maintenance. The partial threading allows the shank to bear shear loads, which is useful in bolted joint designs requiring a grip length. Maintenance technicians, millwrights, and industrial mechanics routinely specify Grade 8 hardware in applications involving vibration, high clamping force, or load-bearing connections. This fastener ships in a minimum order quantity of 10 pieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction for high tensile and proof load strength\u003c\/li\u003e\n  \u003cli\u003eZinc yellow dichromate finish provides corrosion resistance and visual grade identification\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank supports shear load bearing in bolted joints\u003c\/li\u003e\n  \u003cli\u003e9\/16-12 UNC thread for compatibility with standard inch-series nuts and tapped holes\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.2.1 and SAE J429 dimensional and mechanical standards\u003c\/li\u003e\n  \u003cli\u003eMinimum order quantity of 10 pieces per order\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 9\/16-12 UNC inch-series hex nuts, flat washers, and tapped holes conforming to UNC thread standards in industrial and structural fastening applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic or millwright familiar with fastener torque specifications for Grade 8 hardware. Always use a calibrated torque wrench and apply the appropriate torque value per the joint design specification or applicable engineering standard. Ensure mating threads and bearing surfaces are clean and free of damage before assembly. De-energize and lock out any equipment before servicing fastened assemblies per applicable safety procedures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 9\/16-12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Grade 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc Yellow Dichromate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME B18.2.1, SAE J429\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\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: D39139\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51711774097714,"sku":"D39139","price":20.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ab889d99d924292ad91a203e2091ad7a.jpg?v=1788479470","url":"https:\/\/voomisupply.com\/products\/value-collection-d39139-hex-cap-screw-9-16-12-x-3-1-2-in-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
