It carries a zinc yellow dichromate finish that provides corrosion resistance in demanding service environments. The screw is partially threaded and conforms to ASME B18.2.1 dimensional standards. It is sold in packages of 10 and suits applications where high tensile strength fasteners are required. Electricians, pipefitters, millwrights, and general mechanical contractors reach for Grade 8 hardware when joint integrity under load is critical.\u003c\/p\u003e\n\u003cp\u003eThis hex cap screw is suited for structural and mechanical assemblies in industrial, commercial, and heavy-duty trade settings. The 5\/8-11 UNC thread pattern is a common coarse-thread standard used across equipment frames, flanged connections, machinery bases, and support structures. The partially threaded shank allows for a bearing surface in the grip area, which is important when clamping thick or stacked material without relying solely on thread engagement.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction for high tensile and proof-load strength\u003c\/li\u003e\n  \u003cli\u003e5\/8-11 UNC coarse thread for broad hardware compatibility\u003c\/li\u003e\n  \u003cli\u003e6-inch length under head with partial threading for proper grip-area clamping\u003c\/li\u003e\n  \u003cli\u003eZinc yellow dichromate finish for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.2.1 dimensional standards\u003c\/li\u003e\n  \u003cli\u003eSold in a package of 10 units\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 5\/8-11 UNC hex head cap screw conforming to ASME B18.2.1, suitable for use wherever a Grade 8 coarse-thread fastener of this size is specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified tradesperson familiar with fastener torque requirements for Grade 8 hardware. Always de-energize, depressurize, or otherwise render safe any equipment before fastener service. Use a calibrated torque wrench and consult the equipment manufacturer's torque specification for 5\/8-11 Grade 8 fasteners. Inspect threads and mating surfaces for damage before installation to ensure full thread engagement and proper clamp load.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-11\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull or Partial Threading\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\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B18.2.1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 10\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: MP39161\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51689839755570,"sku":"MP39161","price":57.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/28622ceabab33bfecd7b53a1036fbfd3.jpg?v=1788264483","url":"https:\/\/voomisupply.com\/products\/value-collection-mp39161-hex-cap-screw-5-8-11-x-6-in-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
