It follows UNC thread standards and conforms to ASME B18.2.1 and SAE J429 specifications. The length is measured under the head at 8 inches, and the thread size is 7\/8-9. This fastener is commonly installed by millwrights, maintenance mechanics, pipefitters, and general contractors in structural and mechanical assembly applications where a standard-duty hex cap screw is required.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for general-purpose fastening in industrial, commercial, and light structural applications. Partially threaded shanks provide clamping force and reduce thread engagement in the grip area, making them a preferred choice for bolted joint assemblies where shear load distribution matters. The zinc-plated finish provides basic corrosion resistance for indoor and light-duty outdoor environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7\/8-9 UNC thread size for broad tool and nut compatibility\u003c\/li\u003e\n  \u003cli\u003e8-inch length under head suits deep-reach bolted assemblies\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank improves shear resistance in bolted joints\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction meets SAE J429 mechanical requirements\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides basic corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.1 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose hex head cap screw compatible with standard 7\/8-9 UNC hex nuts and washers in inch-measurement fastener assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by qualified mechanics or maintenance personnel using standard 1-5\/16-inch hex tooling. Ensure mating threads and bearing surfaces are clean and free of debris before assembly. Apply thread lubricant or anti-seize as required by the application and applicable standards. Always follow the torque requirements specified in the relevant engineering drawings or industry fastener standards for Grade 2 hardware.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/8-9\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 8 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 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\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\u003eWeight\u003c\/strong\u003e: 1.51 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: 87128CH2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693338820914,"sku":"87128CH2","price":32.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/91d230f6d231b2639aa66cb97e698a94.jpg?v=1788310877","url":"https:\/\/voomisupply.com\/products\/value-collection-87128ch2-hex-head-cap-screw-7-8-9-x-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
