Manufactured from Grade 8 steel with a zinc yellow dichromate finish, this fastener delivers elevated tensile strength and corrosion resistance suitable for demanding installations. The screw measures 4.5 inches under the head and features a partially threaded shank, which provides improved clamping force in bolted joint assemblies. It conforms to ASME B18.2.1 dimensional standards. Licensed tradespeople, millwrights, pipefitters, and mechanical contractors working with structural assemblies, equipment mounting, and heavy-duty connections will find this fastener appropriate for their service work.\u003c\/p\u003e\u003cp\u003eThis hex head cap screw is suited for use in industrial machinery, structural steel connections, heavy equipment assembly, and mechanical installations requiring high-strength fasteners. The 3\/4-16 UNF thread specification is a fine-thread designation, providing greater thread engagement and resistance to loosening under vibration compared to coarse-thread equivalents. The partially threaded design is particularly well-matched for through-bolt applications where a grip length is needed between mating components. Sold individually, with a minimum order quantity of 10 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade 8 steel construction for high tensile and proof load capacity\u003c\/li\u003e\n\u003cli\u003eZinc yellow dichromate finish provides corrosion resistance and visual identification of Grade 8 rating\u003c\/li\u003e\n\u003cli\u003e3\/4-16 UNF fine-thread specification for improved vibration resistance and thread engagement\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank allows for full clamping load across the grip length\u003c\/li\u003e\n\u003cli\u003eConforms to ASME B18.2.1 dimensional standards for hex head cap screws\u003c\/li\u003e\n\u003cli\u003e4.5-inch length under head suits through-bolt and deep clearance applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard ASME B18.2.1 hex head cap screw suitable for use in any application requiring a 3\/4-16 UNF partially threaded fastener in Grade 8 steel.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by qualified tradespeople familiar with proper fastener torque procedures for Grade 8 hardware. Always verify thread engagement depth and joint material compatibility before installation. Use of a calibrated torque wrench is standard practice when installing high-strength fasteners in structural or mechanical assemblies. Follow all applicable equipment manufacturer specifications and relevant mechanical codes for fastener selection and installation procedures.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/4-16\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\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\u003eStandard\u003c\/strong\u003e: ASME B18.2.1\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\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: D39481\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692896190770,"sku":"D39481","price":44.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e1f6ba9d07421c33e2fc14ac661bc403.jpg?v=1788304665","url":"https:\/\/voomisupply.com\/products\/value-collection-d39481-hex-head-cap-screw-3-4-16-4-1-2-in-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
