It features a 5\/8-18 UNF thread — a fine-pitch unified thread that provides greater tensile strength and better resistance to vibration loosening compared to coarse-thread equivalents. The screw measures 1-3\/4 inches under the head and is fully threaded along that length. It is driven with a 1\/2-inch hex (Allen) key. Constructed from alloy steel with a black oxide coating, it meets ASME\/ANSI B18.3 and ASTM A574 standards, making it appropriate for structural and precision mechanical use.\u003c\/p\u003e\n\u003cp\u003eThis screw is commonly used in machine construction, fixture building, jig fabrication, and general industrial assembly wherever a socket-drive cap screw is specified. The fine 5\/8-18 UNF thread pitch suits applications requiring tight clamping force or precise torque control. Machinists, millwrights, and maintenance technicians install this type of fastener in equipment frames, motor mounts, brackets, and similar assemblies. The black oxide finish provides moderate corrosion resistance and reduces surface reflectivity in low-visibility environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8-18 UNF fine-thread specification for high tensile load and vibration resistance\u003c\/li\u003e\n  \u003cli\u003eFully threaded shank along the full 1-3\/4 inch under-head length\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch hex socket drive for use with standard Allen keys or hex bit drivers\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 mechanical requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide coating for moderate corrosion protection and low-reflectance finish\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 suitable for use in any application calling for a 5\/8-18 UNF fully threaded socket cap screw in alloy steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a 1\/2-inch hex key or Allen driver; use calibrated torque tools where assembly specifications require a defined clamp load. Ensure mating threads are clean and free of debris before installation. Follow applicable ASME or equipment OEM torque guidelines for 5\/8-18 fasteners in the specific material being fastened. Alloy steel fasteners should not be mixed with dissimilar metals in corrosive environments without appropriate isolation.\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: 1-3\/4 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 Coating\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  \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: 011453BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51723865686322,"sku":"011453BR","price":29.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1520e6a88b202748aa3c48b0e054fb56.jpg?v=1788609007","url":"https:\/\/voomisupply.com\/products\/value-collection-011453br-hex-socket-cap-screw-5-8-18-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
