It features a 5\/8-18 UNF thread size and measures 1-1\/2 inches in length under the head. The 1\/2 inch hex drive accepts standard hex keys and torque tools. Constructed from alloy steel and finished with a black oxide coating, this screw delivers solid mechanical strength with modest corrosion resistance. It meets ASME\/ANSI B18.3 and ASTM A574 standards, making it suitable for demanding industrial, mechanical, and structural assembly work performed by machinists, maintenance technicians, and millwrights.\u003c\/p\u003e\n\u003cp\u003eThis screw is a general-purpose socket cap fastener suited for machine assemblies, fixtures, tooling, and equipment frames where a recessed drive is preferred for clearance or torque reasons. The fine 18-thread-per-inch pitch provides precise clamping force and resistance to loosening under vibration, which is an advantage in dynamic machinery environments. Sold individually with a minimum order quantity of 25 pieces, it is appropriate for shop stock replenishment or production builds requiring consistent, standards-compliant hardware.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8-18 UNF fully threaded profile for precise thread engagement and vibration resistance\u003c\/li\u003e\n  \u003cli\u003e1-1\/2 inch length under head accommodates medium-depth clamping applications\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch hex drive compatible with standard hex keys and socket drive tools\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 high-strength requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion protection 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 ASME\/ANSI B18.3 hex socket cap screw for use in any application requiring a 5\/8-18 UNF fully threaded fastener with a 1\/2 inch hex drive.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by machinists, millwrights, or maintenance technicians using a 1\/2 inch hex key or socket drive tool. Always ensure mating threads are clean and free of debris before installation. Follow engineering drawings or equipment service manuals for torque requirements, as this product ships without application-specific torque values. Black oxide coating offers minimal corrosion resistance and should not be relied upon as a substitute for plated or stainless hardware in wet or outdoor environments.\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: 1-1\/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\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\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: 40267\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51690822172978,"sku":"40267","price":68.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9a1267201dd09d738fea7604db2ab537.jpg?v=1788275741","url":"https:\/\/voomisupply.com\/products\/value-collection-40267-hex-socket-cap-screw-5-8-18-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
