It features a 3\/8-16 UNC thread and measures 3.5 inches under the head. Grade 8 steel provides high tensile strength suited for demanding fastening applications where standard-grade hardware is not adequate. The zinc yellow dichromate coating adds corrosion resistance. This fastener conforms to ASME B18.2.1 dimensional standards and is installed by millwrights, maintenance technicians, and mechanical contractors across industrial and commercial settings.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is well suited for structural and mechanical assemblies where high-strength fasteners are required. Typical applications include machinery mounting, equipment frames, brackets, and heavy-duty fixture work. The partial threading allows the unthreaded shank to bear shear loads, making it appropriate for joints where load distribution across the grip length matters. It is a common replacement or stock fastener in maintenance, repair, and operations (MRO) environments.\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\u003eZinc yellow dichromate finish provides corrosion resistance\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank supports shear load applications\u003c\/li\u003e\n  \u003cli\u003e3\/8-16 UNC thread form for compatibility with standard inch-series nuts and tapped holes\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 use with 3\/8-16 UNC tapped holes and nuts in industrial, commercial, and mechanical assembly applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified mechanics or maintenance technicians using a standard hex wrench or socket driver sized for a 3\/8-16 fastener. De-energize and isolate any equipment before fastening into powered machinery or structural assemblies. Do not exceed the torque rating specified by the equipment manufacturer or applicable fastener engineering standards for Grade 8 hardware. Inspect threads on both the fastener and the mating part for damage before installation.\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: 3.5 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\u003eDimensional Standard\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\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: D39064\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694266908978,"sku":"D39064","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/14dc6ec1482c1cb1465d0af202ea4186.jpg?v=1788322401","url":"https:\/\/voomisupply.com\/products\/value-collection-d39064-hex-head-cap-screw-3-8-16-x-3-5-in-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
