Manufactured from Grade 8 steel with a zinc yellow dichromate finish, this fastener delivers elevated tensile strength and corrosion resistance compared to lower-grade alternatives. The 1\/2-20 UNF thread pattern provides fine-thread engagement for applications requiring precise torque control and resistance to loosening under vibration. Conforming to ASME B18.2.1 and SAE J429 standards, this screw meets recognized dimensional and mechanical requirements for commercial and industrial use. Sold in a package quantity of 25.\u003c\/p\u003e\u003cp\u003eThis fastener is suited for equipment assembly, machinery maintenance, and structural connections where Grade 8 strength is specified. The fine unified thread (UNF) designation makes it appropriate for applications involving vibration-prone environments or where higher thread engagement per inch is required. Typical users include maintenance technicians, millwrights, equipment fabricators, and trade professionals working on HVAC equipment frames, pump assemblies, compressor mounts, and similar mechanical systems requiring a reliable high-strength fastener.\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\u003eZinc yellow dichromate finish provides corrosion resistance and surface protection\u003c\/li\u003e\n\u003cli\u003eFully threaded along the full length under head for maximum thread engagement\u003c\/li\u003e\n\u003cli\u003e1\/2-20 UNF fine thread pattern resists loosening under vibration\u003c\/li\u003e\n\u003cli\u003eMeets ASME B18.2.1 and SAE J429 dimensional and mechanical standards\u003c\/li\u003e\n\u003cli\u003eSold in a 25-piece package for job-lot convenience\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 1\/2-20 UNF Grade 8 hex head cap screw suitable for use in any application specifying this thread size, length, and material grade per ASME B18.2.1 and SAE J429 requirements.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by qualified mechanical or trade personnel familiar with fastener torque requirements for Grade 8 hardware. Always verify the mating thread specification matches 1\/2-20 UNF before installation. Power down or de-energize any connected equipment before fastener service on mechanical assemblies. Use calibrated torque tooling and follow the torque values specified in the equipment manufacturer's service documentation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 1.5 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 8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc Yellow Dichromate\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\u003ePackage Quantity\u003c\/strong\u003e: 25\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: MP39406\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51698466390322,"sku":"MP39406","price":36.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/079f2ef646838b10ac7c2c0f6536ecd7.jpg?v=1788363312","url":"https:\/\/voomisupply.com\/products\/value-collection-mp39406-hex-cap-screw-1-2-20-x-1-1-2-in-grade-8-25pk","provider":"Voomi Supply","version":"1.0","type":"link"}
