It features a 5\/16-18 UNC thread and a 4-1\/2 inch length under head, with partial threading along the shank. The zinc yellow dichromate finish provides corrosion resistance and serves as a visual identifier for Grade 8 hardware. Manufactured to ASME B18.2.1 standards, this fastener delivers the dimensional consistency and tensile strength required in demanding mechanical, structural, and equipment assembly applications. Each order contains 25 screws.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for use in industrial machinery, mechanical assemblies, structural brackets, and equipment fabrication where high-strength inch-series fasteners are specified. The partial threading is appropriate for clamping applications where a full-thread grip length is not required or where a smooth shank is needed through the clamped material. Maintenance technicians, millwrights, and mechanical contractors commonly use Grade 8 hardware of this type in both new construction and retrofit work.\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\/16-18 UNC thread for standard inch-series fastener compatibility\u003c\/li\u003e\n  \u003cli\u003e4-1\/2 inch length under head suits deep-reach clamping applications\u003c\/li\u003e\n  \u003cli\u003ePartial threading provides a smooth shank section for clean clamping interfaces\u003c\/li\u003e\n  \u003cli\u003eZinc yellow dichromate finish offers corrosion resistance and Grade 8 visual identification\u003c\/li\u003e\n  \u003cli\u003eManufactured to ASME B18.2.1 for consistent dimensional tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series Grade 8 hex head cap screw for use with 5\/16-18 UNC threaded holes, nuts, and inserts in steel, cast iron, and similar structural materials.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by mechanical technicians and tradespeople using a standard hex socket or open-end wrench. Always confirm the mating thread is 5\/16-18 UNC before installation and inspect threads for damage before torquing. Do not mix Grade 8 fasteners with non-Grade-rated nuts unless the assembly is engineered for that combination. Follow applicable torque specifications from the equipment manufacturer or a recognized fastener standard for the joint material and finish type.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 4-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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: 25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: MP39040-1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51701188591922,"sku":"MP39040-1","price":33.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c2087f6d4876d58514b2b82550b54ffa.jpg?v=1788399490","url":"https:\/\/voomisupply.com\/products\/value-collection-mp39040-1-hex-cap-screw-5-16-18-grade-8-25pk","provider":"Voomi Supply","version":"1.0","type":"link"}
