Built to Grade 8 steel specifications, this fastener delivers a high tensile strength suitable for demanding bolted connections. It measures 5\/8-18 thread size with a 2-3\/4 inch length under head and is finished with a zinc yellow dichromate coating that provides corrosion resistance and meets ASME B18.2.1 dimensional standards. Machinists, millwrights, and maintenance mechanics rely on this screw class for critical fastener applications.\u003c\/p\u003e\u003cp\u003eThis hex head cap screw is suited for general industrial assembly, equipment maintenance, and structural mechanical work where a UNF thread form and partial threading are required. The 5\/8-18 UNF thread designation makes it appropriate for applications requiring finer thread engagement than a coarse-thread counterpart. Typical uses include machinery frames, jig and fixture assemblies, and heavy equipment repair. Sold individually with a minimum order quantity of 10 units per purchase.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade 8 steel construction for high tensile and proof load strength\u003c\/li\u003e\n\u003cli\u003e5\/8-18 UNF thread for fine-thread engagement and precise clamping\u003c\/li\u003e\n\u003cli\u003e2-3\/4 inch length under head with partial threading for bearing-surface contact\u003c\/li\u003e\n\u003cli\u003eZinc yellow dichromate finish for corrosion and oxidation resistance\u003c\/li\u003e\n\u003cli\u003eConforms to ASME B18.2.1 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard UNF hex head cap screw compatible with 5\/8-18 threaded holes and nuts conforming to ASME B18.2.1 specifications in inch-system mechanical assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by qualified mechanics or maintenance technicians using a properly sized hex wrench or socket. Always verify thread engagement depth and hole condition before driving the fastener. Do not exceed the rated torque for Grade 8 fasteners of this diameter as specified by applicable engineering standards. Inspect the mating threaded component for thread damage or contamination before assembly.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-18\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 2-3\/4 inches\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 Coating\u003c\/strong\u003e: Zinc Yellow Dichromate\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\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: D39452\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720132788530,"sku":"D39452","price":30.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d6b38e0f9feaf8ced7f9dfd95d68e420.jpg?v=1788560953","url":"https:\/\/voomisupply.com\/products\/value-collection-d39452-hex-head-cap-screw-5-8-18","provider":"Voomi Supply","version":"1.0","type":"link"}
