Sized at 1\/2-20 UNF with a 1-3\/4 inch length under head, this screw is manufactured from Grade 8 steel and finished with zinc yellow dichromate for corrosion resistance. It conforms to ASME B18.2.1, the standard governing inch-series hex cap screws. Sold in packs of 25, these fasteners are suited for mechanical assemblies, structural connections, and equipment maintenance tasks where Grade 8 tensile strength is required. Installation is handled by maintenance technicians, millwrights, and general tradespeople across industrial and commercial settings.\u003c\/p\u003e\n\u003cp\u003eThis screw is appropriate for use in applications demanding fine-thread engagement and high clamp load, such as automotive, heavy equipment, and industrial machinery repairs. The 1\/2-20 UNF thread pitch provides tighter thread engagement per inch compared to coarse-thread equivalents, making it a common choice where vibration resistance or precision torque control is needed. The fully threaded body maximizes thread engagement across the entire length under head.\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 capacity\u003c\/li\u003e\n  \u003cli\u003eZinc yellow dichromate finish provides corrosion and oxidation resistance\u003c\/li\u003e\n  \u003cli\u003eFully threaded body along the 1-3\/4 inch length under head\u003c\/li\u003e\n  \u003cli\u003e1\/2-20 UNF thread standard for fine-pitch engagement\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.2.1 dimensional standards\u003c\/li\u003e\n  \u003cli\u003eSold in a pack of 25 for stocking and job-site use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series hex head cap screw for use in any application requiring a 1\/2-20 UNF Grade 8 fastener conforming to ASME B18.2.1.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using an appropriate hex socket or open-end wrench sized for a 1\/2-inch hex cap screw. Follow torque specifications established by the equipment manufacturer or applicable engineering standards for Grade 8 fasteners. Ensure mating threads are clean and free of debris before installation. Do not use impact tools without a verified torque-limiting method to avoid overloading the joint.\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 UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull or Partial Threading\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 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\u003ePackage Quantity\u003c\/strong\u003e: 25 pieces\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: MP39407\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51723499766066,"sku":"MP39407","price":38.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8444d23efff05d1944243bf827ecb4b8_1eb84e9b-82b5-4006-a3f1-59e333162060.jpg?v=1788605561","url":"https:\/\/voomisupply.com\/products\/value-collection-mp39407-hex-cap-screw-1-2-20-grade-8-25-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
