Sized at 1\/2-20 UNF with a 2-inch length under head, it uses a 3\/8-inch hex drive for installation with a hex key or Allen driver. The fastener is manufactured from alloy steel and finished with a zinc-plated coating that provides basic corrosion resistance in dry and mildly humid environments. It meets ASTM B695 fastener standards. This screw is commonly installed by millwrights, pipefitters, HVAC technicians, electricians, and general mechanical contractors wherever a high-torque, socket-drive cap screw is required.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for use in structural joints, equipment frames, motor mounts, brackets, and similar assemblies where a flush or recessed fastener head is preferred. The fine 1\/2-20 UNF thread pitch provides tighter thread engagement and greater resistance to loosening under vibration compared to coarse-thread equivalents. It is sold individually but subject to a minimum order quantity of 10 pieces, making it appropriate for both single-repair and small-batch production use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-20 UNF fine thread for improved vibration resistance and torque retention\u003c\/li\u003e\n  \u003cli\u003eFully threaded along the 2-inch shank length under head\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch hex socket drive compatible with standard Allen keys and socket drivers\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction for high tensile and shear strength\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish per ASTM B695 for corrosion protection in general-duty environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/2-20 UNF hex socket cap screw for use in any application requiring a fully threaded, socket-drive fastener of this thread size and shank length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a 3\/8-inch hex key or Allen-head socket driver; use a calibrated torque wrench when a specified clamp load must be maintained. Ensure mating threads are clean and free of debris before installation. Do not mix with coarse-thread (UNC) tapped holes of the same nominal diameter. Follow applicable mechanical codes and equipment manufacturer torque specifications for the assembly being serviced.\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: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Fully Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex Socket\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASTM B695\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 4 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\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: 837401PS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720468201778,"sku":"837401PS","price":1122.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0c9a2a0009891924a2ca223b5da382b3_50b57a18-3d52-42ca-8fed-c3c3958ef5f2.jpg?v=1788564493","url":"https:\/\/voomisupply.com\/products\/value-collection-837401ps-hex-socket-cap-screw-1-2-20-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
