With a 3-inch length under head and partial threading, this fastener provides a bearing surface against unthreaded material, making it suitable for clamping applications where a smooth shank is required through one or more layers. Manufactured from Grade 5 steel with a zinc-plated finish, it meets ASME B18.2.1 dimensional standards. The zinc coating provides a base level of corrosion resistance for indoor and light-duty outdoor environments. Installed using a standard hex wrench or socket, this screw suits maintenance, fabrication, and equipment assembly work.\u003c\/p\u003e\n\u003cp\u003eThis fastener is appropriate for use in residential and commercial mechanical equipment installation, HVAC equipment mounting, electrical enclosure assembly, and general trade service work where 1\/4-20 UNC thread fasteners are specified. The 3-inch length makes it suited for applications requiring reach through thicker material stacks or brackets. Trade professionals in HVAC, plumbing, and electrical disciplines commonly use this thread size and length combination for panel and bracket attachment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-20 UNC thread for broad compatibility with standard inch-system tapped holes\u003c\/li\u003e\n  \u003cli\u003e3-inch length under head with partial threading, providing a smooth shank section for clamping applications\u003c\/li\u003e\n  \u003cli\u003eGrade 5 steel construction for improved tensile strength over Grade 2 fasteners\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish for baseline corrosion resistance in light-duty environments\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.1 dimensional standards for consistent fitment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service fastener for any application specifying a 1\/4-20 UNC hex head cap screw with a 3-inch length under head.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a standard 7\/16-inch hex wrench or socket. Always verify thread engagement depth and torque to the equipment manufacturer specification for 1\/4-20 Grade 5 fasteners. For installations governed by NEC or mechanical codes, confirm fastener grade requirements in the applicable equipment documentation before substituting hardware. Do not overtighten into aluminum or light-gauge steel tapped holes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3 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 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Zinc-Plated\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\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: D30012\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51714343239986,"sku":"D30012","price":67.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ac39e367b6a9d24356c6ad9f35d0aa91.jpg?v=1788499883","url":"https:\/\/voomisupply.com\/products\/value-collection-d30012-hex-head-cap-screw-1-4-20-x-3-in","provider":"Voomi Supply","version":"1.0","type":"link"}
