It features a zinc yellow dichromate finish that provides corrosion resistance in demanding service environments. The screw is partially threaded and manufactured to ASME B18.2.1 standards, making it a reliable choice for structural and mechanical fastening applications. Licensed tradespeople, maintenance mechanics, and industrial assemblers reach for Grade 8 hardware when high tensile strength and dimensional consistency are required on critical joints.\u003c\/p\u003e\u003cp\u003eThis fastener suits a wide range of heavy-duty assembly applications including machinery mounting, structural steel connections, equipment frames, and general industrial maintenance. Its inch-series UNC thread pattern is compatible with standard tapped holes and hex nuts across residential and commercial mechanical installations. The zinc yellow dichromate coating makes it well-suited for indoor and semi-exposed environments where moderate corrosion protection is needed alongside high clamping load requirements.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade 8 steel construction for high tensile and proof load strength\u003c\/li\u003e\n\u003cli\u003e1-8 UNC thread standard ensures compatibility with standard inch-series tapped holes and nuts\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank provides a bearing surface for shear-loaded joints\u003c\/li\u003e\n\u003cli\u003eZinc yellow dichromate finish delivers corrosion resistance without sacrificing torque control\u003c\/li\u003e\n\u003cli\u003eManufactured to ASME B18.2.1 for dimensional accuracy and consistency\u003c\/li\u003e\n\u003cli\u003e3.5-inch length under head accommodates thicker material stackups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or general-use Grade 8 hex head cap screw for inch-series UNC threaded assemblies in industrial, mechanical, and structural applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by qualified mechanics or tradespeople familiar with fastener torque specifications for Grade 8 hardware. Always clean and inspect the mating threaded hole before installation and confirm thread engagement depth meets design requirements. Use a calibrated torque wrench and apply torque values appropriate for the specific joint design and lubrication condition. Do not substitute Grade 8 fasteners with lower-grade hardware in structural or high-load applications.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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\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\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\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: D39219\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51722039886130,"sku":"D39219","price":51.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a8a79d0dd9d6b1683ccd61a3c67137d4.jpg?v=1788584539","url":"https:\/\/voomisupply.com\/products\/value-collection-d39219-hex-head-cap-screw-grade-8-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
