Machined to 5\/8-18 UNF thread specifications, this fastener measures 2 inches under the head and is driven with a 1\/2-inch hex socket. Constructed from alloy steel and finished with a black oxide coating, it meets ASTM A574 standards, which govern mechanical and performance requirements for socket cap screws used in demanding industrial and mechanical assemblies. The black oxide finish provides mild corrosion resistance and reduces light reflection in finished assemblies.\u003c\/p\u003e\n\u003cp\u003eThis socket cap screw is suited for use in mechanical assemblies, industrial machinery, tooling fixtures, and structural joints where a recessed drive profile and high tensile strength are required. Trades including millwrights, pipefitters, and general mechanical contractors commonly use ASTM A574 socket cap screws when torque requirements exceed what standard fasteners can reliably handle. The fine 18 TPI UNF thread pitch provides improved thread engagement and resistance to loosening under vibration.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8-18 UNF fine thread for strong clamping force and vibration resistance\u003c\/li\u003e\n  \u003cli\u003e2-inch length under head, fully threaded for maximum thread engagement\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch hex socket drive compatible with standard hex keys and socket drivers\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 mechanical requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish for mild corrosion resistance and a low-reflectance appearance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-use fastener compatible with any application requiring a 5\/8-18 UNF fully threaded hex socket cap screw meeting ASTM A574 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by qualified mechanical or trade personnel using a properly sized 1\/2-inch hex key or socket driver. Ensure mating threads are clean and free of debris before driving. Always verify thread engagement depth and fastener grade requirements against the assembly specification before installation. Do not substitute fastener grades without confirming that the replacement meets the load and torque requirements of the joint.\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: ASTM A574\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\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: 307366BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693338624306,"sku":"307366BR","price":61.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fe624f9a809e6dbce84bd23799d13c67.jpg?v=1788310871","url":"https:\/\/voomisupply.com\/products\/value-collection-307366br-hex-socket-cap-screw-5-8-18-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
