Manufactured from Grade 8 steel with a zinc yellow dichromate finish, this fastener delivers substantial tensile strength and corrosion resistance in demanding environments. The 1-8 UNC thread size paired with a 3-inch length under the head makes it suitable for heavy-duty bolted connections where clamp load and fatigue resistance are critical. It conforms to ASME B18.2.1 and SAE J429 standards, ensuring dimensional and mechanical consistency for professional use.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is used across a broad range of trade and industrial applications including machinery assembly, structural steel connections, automotive and equipment repair, and general maintenance work requiring a Grade 8 fastener. The UNC thread form is widely compatible with standard hex nuts and tapped holes. The zinc yellow dichromate finish provides moderate corrosion protection suitable for indoor and light outdoor environments. Minimum order quantity is 10 pieces.\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 for corrosion resistance and identification\u003c\/li\u003e\n  \u003cli\u003eFully threaded along the 3-inch length under head for maximum thread engagement\u003c\/li\u003e\n  \u003cli\u003e1-8 UNC thread standard for compatibility with standard hex nuts and tapped holes\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.2.1 and SAE J429 dimensional and mechanical standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 1-inch UNC hex nuts and appropriately tapped holes in Grade 8 or compatible fastener applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by qualified mechanical or structural tradespeople familiar with proper torque procedures for Grade 8 fasteners. Always use a calibrated torque wrench and follow the applicable engineering specifications or fastener torque tables for the joint material and thread size. Inspect the mating threads and hole for cleanliness and damage before installation. Do not mix Grade 8 fasteners with lower-grade nuts or hardware in high-load assemblies.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-8 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Fully 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\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME B18.2.1, SAE J429\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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: D39217\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51713837531442,"sku":"D39217","price":47.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/25969d94a8f46dd7d53333986d5cc13d.jpg?v=1788495319","url":"https:\/\/voomisupply.com\/products\/value-collection-d39217-hex-cap-screw-1-8x3-grade-8-zinc","provider":"Voomi Supply","version":"1.0","type":"link"}
