It carries a Grade 8 steel rating, making it suitable for demanding load-bearing joints where shear and tensile strength matter. The 5\/8-18 UNF thread form provides a fine-thread engagement suitable for precision applications or installations where vibration resistance is a priority. The zinc yellow dichromate finish offers corrosion resistance in moderate-exposure environments. This screw is installed by millwrights, maintenance technicians, and mechanical contractors working on heavy equipment, machinery, and structural connections.\u003c\/p\u003e\n\u003cp\u003eThis fastener is used in industrial maintenance, OEM assembly, and field repair scenarios where a Grade 8, fine-thread cap screw is specified. The partially threaded shank provides a bearing surface in the grip zone, which is important in shear-loaded joint designs. At 5-1\/2 inches under the head with a 5\/8-18 UNF thread, this screw fits applications requiring longer fastener reach through thicker material stacks. Sold in a package quantity of 25, it is well suited for production assembly lines or stocking in maintenance cribs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction for high tensile and shear strength in load-bearing joints\u003c\/li\u003e\n  \u003cli\u003e5\/8-18 UNF fine-thread form for improved vibration resistance and precise torque control\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank provides a smooth bearing surface in the grip zone for shear-loaded applications\u003c\/li\u003e\n  \u003cli\u003eZinc yellow dichromate finish delivers corrosion resistance in moderate-exposure environments\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.2.1 and SAE J429 standards for dimensional and mechanical compliance\u003c\/li\u003e\n  \u003cli\u003ePackage quantity of 25 supports production assembly and maintenance stocking requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style and aftermarket replacement hex head cap screw for industrial machinery, heavy equipment, and structural assemblies requiring a 5\/8-18 UNF Grade 8 fastener with a 5-1\/2 inch length under head.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified mechanical or maintenance technicians. Ensure mating threads are clean and free of debris before installation. De-energize and lock out all equipment per applicable OSHA lockout\/tagout procedures before fastener installation or replacement. Do not reuse fasteners that show signs of thread damage, stretching, or corrosion, as Grade 8 fasteners are torque-sensitive and should not be compromised.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 5-1\/2 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 Coating\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\u003ePackage Quantity\u003c\/strong\u003e: 25\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: 39460\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694112080178,"sku":"39460","price":102.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0e28c9de71cbea11f7515cb34c9eed52.jpg?v=1788320408","url":"https:\/\/voomisupply.com\/products\/value-collection-39460-hex-head-cap-screw-5-8-18-x-5-1-2-in-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
