Sized at 1\/2-20 UNF with a 1-1\/2 inch length under head, this fastener is manufactured from Grade 5 steel and finished with a zinc plating for corrosion resistance in standard service environments. It conforms to ASME B18.2.1, the governing standard for inch-series hex cap screws. Installers working in fabrication, equipment maintenance, or field service will recognize this as a standard-inventory fastener suited to high-volume fastening tasks.\u003c\/p\u003e\n\u003cp\u003eThis screw is appropriate for residential and commercial mechanical applications where a fine-thread UNF fastener is specified. The 1\/2-20 thread pitch provides tighter thread engagement than a coarse-thread equivalent, making it a common choice when vibration resistance or precise torque control is a priority. It is used by HVAC technicians, pipefitters, electricians, and general maintenance trades for panel mounting, bracket attachment, and equipment assembly tasks requiring a standardized hex drive fastener.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-20 UNF fine-thread profile for tighter thread engagement and improved vibration resistance\u003c\/li\u003e\n  \u003cli\u003e1-1\/2 inch length under head for standard through-bolt and tapped-hole applications\u003c\/li\u003e\n  \u003cli\u003eGrade 5 steel construction for reliable tensile strength in medium-duty fastening\u003c\/li\u003e\n  \u003cli\u003eZinc plating provides corrosion resistance in typical indoor and sheltered outdoor environments\u003c\/li\u003e\n  \u003cli\u003eFully threaded shank maximizes thread engagement across the full grip length\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.2.1 for dimensional consistency and interchangeability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard UNF inch-series hex head cap screw compatible with any 1\/2-20 tapped hole or matching nut conforming to ASME B18.2.1 dimensional requirements.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a standard hex wrench, socket, or ratchet sized for a 1\/2-20 fastener. Ensure the mating thread is clean and free of debris before installation. Do not exceed the torque specification for Grade 5 fasteners as defined by the application engineer or equipment manufacturer. When replacing fasteners in electrical enclosures or pressurized systems, de-energize and depressurize the system before service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\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 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\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: D30281\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51711284347186,"sku":"D30281","price":37.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c027f6db29efc4eeafec760d2f9e3140.jpg?v=1788475313","url":"https:\/\/voomisupply.com\/products\/value-collection-d30281-hex-head-cap-screw-1-2-20","provider":"Voomi Supply","version":"1.0","type":"link"}
