It features a 5\/8-18 UNF thread and a 7-inch length under head, machined from Grade 5 steel and finished with a zinc plating for corrosion resistance. The hex drive accepts a 15\/16-inch hex key or wrench. This fastener conforms to ASME B18.2.1 and SAE J429 standards, making it a recognized choice for applications where dimensional and strength compliance are required. Machinists, millwrights, and maintenance technicians are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for general industrial and mechanical assembly where a fine-thread UNF fastener is specified. The partially threaded shank provides a smooth bearing surface through a portion of the grip length, which is useful in applications requiring precise bolt alignment or where the fastener passes through clearance holes before engaging a tapped bore. It is appropriate for use in equipment maintenance, fabrication, and structural fastening in both shop and field environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8-18 UNF thread for fine-pitch engagement and vibration resistance\u003c\/li\u003e\n  \u003cli\u003e7-inch length under head accommodates deep grip applications\u003c\/li\u003e\n  \u003cli\u003eGrade 5 steel construction meets SAE J429 minimum tensile strength requirements\u003c\/li\u003e\n  \u003cli\u003eZinc plating provides basic corrosion and oxidation resistance\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank offers a smooth bearing surface along the grip\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 standard inch-series hex head cap screw for any application specifying a 5\/8-18 UNF partially threaded fastener per ASME B18.2.1 and SAE J429.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a 15\/16-inch open-end, box-end, or socket wrench. Ensure the mating tapped hole or nut is clean and free of debris before threading. Apply thread lubricant or anti-seize compound as required by the assembly specification to achieve accurate clamp load. Do not exceed the proof load for Grade 5 fasteners; consult engineering documentation for application-specific torque values.\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: 7 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 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Key Size\u003c\/strong\u003e: 15\/16 inches\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\u003eWeight\u003c\/strong\u003e: 0.66 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\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: 457456BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51707643429170,"sku":"457456BR","price":16.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5ad409ecadd70d4bf2c1e5ca4d939f38.jpg?v=1788441386","url":"https:\/\/voomisupply.com\/products\/value-collection-457456br-hex-head-cap-screw-5-8-18-x-7-in","provider":"Voomi Supply","version":"1.0","type":"link"}
