Manufactured from alloy steel with a black oxide finish, it offers solid corrosion resistance in moderate environments and the tensile strength expected from an ASTM A574-compliant fastener. The screw measures 6-1\/2 inches in length under head with a 3\/8-16 UNC thread and accepts a 5\/16-inch hex drive. It is partially threaded, making it suitable for applications that require a smooth shank section to bear shear loads or locate components accurately.\u003c\/p\u003e\n\u003cp\u003eThis fastener is used in a wide range of industrial and trade applications including machinery assembly, equipment mounting, structural fabrication, and maintenance repair work. The 3\/8-16 UNC coarse thread offers reliable engagement in steel and iron components and resists cross-threading in field conditions. It is suitable for both shop and field installation by millwrights, pipefitters, ironworkers, and general mechanical technicians working on production equipment, frames, brackets, and structural connections.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 and ASME\/ANSI B18.3 standards for high-strength socket cap screws\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides moderate corrosion resistance and reduces light reflection in service environments\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank allows precise component location and shear load transfer\u003c\/li\u003e\n  \u003cli\u003e3\/8-16 UNC coarse thread for reliable engagement in standard tapped holes\u003c\/li\u003e\n  \u003cli\u003e5\/16-inch hex drive socket for installation with standard Allen keys or hex bit drivers\u003c\/li\u003e\n  \u003cli\u003e6-1\/2-inch length under head suits deep-reach fastening applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use fastener for applications requiring a 3\/8-16 UNC partially threaded hex socket cap screw conforming to ASME\/ANSI B18.3 and ASTM A574 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a 5\/16-inch hex key or socket driver. Ensure the mating tapped hole is clean and free of debris before driving the fastener. De-energize or lock out any equipment before performing fastener installation or replacement per applicable OSHA lockout\/tagout procedures. Do not substitute a smaller drive tool, as rounding the socket will damage the fastener head.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 6-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially 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: 5\/16 inches\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 and ASTM A574\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.22 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: 581481PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691522294066,"sku":"581481PR","price":10078.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d065f0f12ebac5c6887ddf6914d48a43.jpg?v=1788286440","url":"https:\/\/voomisupply.com\/products\/value-collection-581481pr-hex-socket-cap-screw-3-8-16-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
