Manufactured from Grade 8 steel with a zinc yellow dichromate finish, this fastener delivers superior tensile strength and corrosion resistance compared to lower-grade hardware. The 3\/8-16 UNC thread pattern and 2-3\/4 inch length under head make it a dependable choice for structural assemblies, equipment mounting, and heavy-duty mechanical connections. The partial threading is intentional, providing a smooth shank section that resists shear forces in load-bearing joints. Machinists, millwrights, and maintenance technicians routinely specify Grade 8 fasteners for critical connections.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for industrial, commercial, and heavy-duty residential mechanical applications where standard Grade 2 or Grade 5 hardware is insufficient. Common uses include equipment frames, motor mounts, HVAC structural brackets, compressor bases, and general fabrication work requiring a high-clamp-load fastener. The 3\/8-16 UNC threading is one of the most widely used coarse-thread sizes in inch-standard mechanical assemblies, ensuring broad tool and nut compatibility across job sites and shops.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction provides high tensile and yield strength for demanding load-bearing applications\u003c\/li\u003e\n  \u003cli\u003eZinc yellow dichromate finish offers corrosion resistance and a distinctive gold-tone identification color standard for Grade 8 fasteners\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank resists shear forces in structural and mechanical joints\u003c\/li\u003e\n  \u003cli\u003e3\/8-16 UNC coarse thread pattern for broad compatibility with standard inch-system hardware\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.1 dimensional standards for consistent fit across tools and mating hardware\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 compatible with 3\/8-16 UNC threaded nuts, inserts, and tapped holes in steel, iron, and structural assemblies conforming to inch-standard fastener specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, millwrights, or maintenance technicians using a standard hex wrench or socket set. Always use a calibrated torque wrench and follow the applicable fastener torque specification table for Grade 8 hardware at 3\/8-16 thread size. Inspect mating threads and bearing surfaces for damage before assembly. Do not mix Grade 8 fasteners with lower-grade nuts, as mismatched hardware can compromise joint integrity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16\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\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 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\u003eDimensional Standard\u003c\/strong\u003e: ASME B18.2.1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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\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: D39061\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51701003485490,"sku":"D39061","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/be7067f013eaca8429a92673198d9f8f.jpg?v=1788396596","url":"https:\/\/voomisupply.com\/products\/value-collection-d39061-hex-head-cap-screw-3-8-16-x-2-3-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
