It features a 5\/8-18 UNF thread form — a fine-pitch thread that delivers superior clamp load and vibration resistance compared to coarse-pitch equivalents. The screw is manufactured from alloy steel and finished with a black oxide coating that provides mild corrosion resistance and a low-reflectivity surface. Drive size is 1\/2 inch hex socket. Length under head is 2-1\/2 inches with partial threading. Licensed mechanical contractors, maintenance technicians, and toolmakers are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis fastener is suited for precision assemblies where fine-thread engagement is required, including machine components, jigs, fixtures, and hydraulic or pneumatic equipment mounting. The partial threading allows for full shank bearing load in clearance-fit applications. Black oxide finish makes it appropriate for controlled-environment installations where light corrosion protection is acceptable and appearance is a consideration. Sold individually; minimum order quantity is 10 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8-18 UNF fine-pitch thread for high clamp load and vibration resistance\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASME\/ANSI B18.3 and ASTM A574 standards\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank supports shear load in clearance-fit applications\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch hex socket drive for standard Allen key or socket tooling\u003c\/li\u003e\n  \u003cli\u003eBlack oxide coating provides mild corrosion protection and low reflectivity\u003c\/li\u003e\n  \u003cli\u003e2-1\/2-inch length under head suitable for thick-stack mechanical assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard ASME\/ANSI B18.3 and ASTM A574 hex socket cap screw for use in any application requiring a 5\/8-18 UNF fine-thread fastener with a 1\/2-inch hex drive.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by mechanical technicians, millwrights, or maintenance personnel using a 1\/2-inch hex key or socket driver. De-energize and lock out all equipment before fastener installation or removal in powered assemblies. Verify thread engagement and hole condition before installation; damaged or cross-threaded holes should be chased or replaced before use. Black oxide finish is not a substitute for corrosion-resistant coatings 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: 2-1\/2 inches\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\u003eThreading\u003c\/strong\u003e: Partially Threaded\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; ASTM A574\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.28 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: 011457BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693771489586,"sku":"011457BR","price":26.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/487af033edddaa9cb7f04cf575933eba.jpg?v=1788317167","url":"https:\/\/voomisupply.com\/products\/value-collection-011457br-hex-socket-cap-screw-5-8-18-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
