This fastener features a 1\/2-20 UNF thread size with a 1 inch length under the head and is fully threaded for maximum thread engagement. The 3\/8 inch hex drive accepts a standard Allen wrench or hex bit driver. Constructed from alloy steel with a zinc-plated finish, this screw delivers solid corrosion resistance in moderate-exposure environments. It meets ASTM B695 standards for zinc coating. Machinists, millwrights, and maintenance technicians are the typical installers for this style of fastener.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for use in precision mechanical assemblies, machine frames, tooling fixtures, and general industrial fastening where fine-thread engagement and high clamp load are required. The 1\/2-20 UNF fine thread provides tighter thread pitch compared to coarse-thread equivalents, making it a common choice in applications requiring precise torque control or vibration resistance. It is commonly used in metal-to-metal connections in manufacturing, equipment maintenance, and fabrication environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-20 UNF fine thread for precise torque control and vibration resistance\u003c\/li\u003e\n  \u003cli\u003e1 inch length under head, fully threaded for maximum engagement\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch hex socket drive compatible with standard Allen keys and hex bit drivers\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction for high tensile strength\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish meeting ASTM B695 for moderate corrosion protection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard hex socket cap screw for mechanical assemblies, industrial equipment, and fabrication applications requiring a 1\/2-20 UNF fine-thread fastener.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, millwrights, or maintenance technicians using a 3\/8 inch hex key or Allen-drive bit. De-energize and lock out any equipment before performing fastener service on live machinery. Ensure mating threads are clean and free of debris before installation. Do not exceed torque ratings for the specific application and material being fastened.\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 inch\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\u003eDrive Type\u003c\/strong\u003e: Hex Socket\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 3\/8 inch\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\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: 837393PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51700575764786,"sku":"837393PR","price":805.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dc64665761aabd6579fed49a1ce0e918.jpg?v=1788392158","url":"https:\/\/voomisupply.com\/products\/value-collection-837393pr-hex-socket-cap-screw-1-2-20-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
