This fastener features a 5\/8-18 UNF thread size with a 2-inch length under head and is fully threaded from tip to head. The 1\/2-inch internal hex drive allows for high-torque installation using a standard Allen or hex key. Constructed from alloy steel with a black oxide finish, the screw offers good corrosion resistance in controlled environments and maintains strength under mechanical stress. It meets ASME\/ANSI B18.3 and ASTM A574 standards, confirming compliance with recognized fastener specifications for socket cap screws.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for use in industrial machinery, manufacturing fixtures, equipment frames, and precision mechanical assemblies where a low-profile, high-clamp-load fastener is required. The fine UNF thread pitch provides stronger thread engagement and better resistance to loosening under vibration compared to coarse-thread equivalents. Ideal for metal-to-metal fastening in tight-clearance applications where a socket drive is preferred over a hex bolt head. Sold in a minimum order quantity of 25 pieces per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8-18 UNF fine thread for high thread engagement and vibration resistance\u003c\/li\u003e\n  \u003cli\u003e2-inch length under head, fully threaded for maximum fastening versatility\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch hex socket drive for high-torque installation with standard hex keys\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 for high-strength socket cap screws\u003c\/li\u003e\n  \u003cli\u003eBlack oxide coating provides mild corrosion resistance and reduces light reflection\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME\/ANSI B18.3 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-dimension hex socket cap screw per ASME\/ANSI B18.3, compatible with any 5\/8-18 UNF tapped hole application requiring a socket cap screw with a 2-inch grip length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic or assembler using a calibrated 1\/2-inch hex key or Allen driver. Verify the tapped hole thread specification matches 5\/8-18 UNF before installation. Clean threads and mating surfaces before assembly to ensure proper seating and clamp load. Apply thread lubricant or thread-locking compound as required by the assembly specification.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-18 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: 1\/2 inch\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\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 40269\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51723530764594,"sku":"40269","price":79.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0d19c691a0e4ffa8b3d8667958c8d6fa.jpg?v=1788605882","url":"https:\/\/voomisupply.com\/products\/value-collection-40269-hex-socket-cap-screw-5-8-18-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
