Built from alloy steel with a black oxide finish, this fastener resists corrosion and reduces light reflection in finished assemblies. The 1\/2-20 UNF thread provides a fine-pitch connection suited for applications where vibration resistance or precise torque control is important. The 3\/8-inch hex drive socket head accepts a standard hex key or Allen wrench for secure installation. This screw is commonly installed by mechanical assemblers, maintenance technicians, and trade professionals working on machinery, structural components, and equipment frames.\u003c\/p\u003e\n\u003cp\u003eThis fastener is appropriate for general industrial, mechanical, and trade assembly applications requiring a fine-thread, partially threaded socket cap screw. With a 2-1\/2-inch length under head and alloy steel construction, it is well suited for medium-to-heavy fastening tasks in both shop and field environments. The black oxide coating makes it a practical choice where a low-profile, non-reflective finish is preferred. It meets ASME\/ANSI B18.3 and ASTM A574 standards, confirming dimensional and mechanical compliance for demanding fastening applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-20 UNF fine thread for superior vibration resistance and precise torque engagement\u003c\/li\u003e\n  \u003cli\u003e2-1\/2-inch length under head for deep fastening in medium-to-heavy assemblies\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank provides a grip area for shear load applications\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction delivers high tensile strength for demanding mechanical use\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish reduces corrosion and surface reflection\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM A574 standards for dimensional and mechanical compliance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-fitment fastener for assemblies requiring a 1\/2-20 UNF partially threaded hex socket cap screw with a 3\/8-inch drive and 2-1\/2-inch length under head.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a 3\/8-inch hex key or Allen wrench; use a calibrated torque wrench when a specific clamp load is required by the assembly specification. Ensure mating threaded holes are clean, free of debris, and properly tapped to 1\/2-20 UNF before fastening. De-energize and lock out any equipment before accessing fastener locations on powered machinery, following applicable OSHA lockout\/tagout procedures. Do not exceed the rated torque for the fastener grade as defined in ASTM A574 specifications.\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: 2-1\/2 inches\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\u003eThreading\u003c\/strong\u003e: Partially Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME\/ANSI B18.3; ASTM A574\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 25\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: 40262\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51697309221170,"sku":"40262","price":60.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/697e40eea2141e34db75f52a23d60533.jpg?v=1788351078","url":"https:\/\/voomisupply.com\/products\/value-collection-40262-hex-socket-cap-screw-1-2-20-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
