The fastener measures 12 inches in length under the head and is partially threaded along its shank. It is manufactured from alloy steel with a black oxide finish applied for corrosion resistance and reduced surface reflectivity. The 5\/8-11 UNC thread pattern is a coarse-thread specification suited for applications requiring rapid assembly or where minor thread damage is a concern. Drive size is 1\/2 inch hex socket. Machinists, millwrights, and maintenance technicians are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for structural and mechanical connections in industrial equipment, machinery frames, jigs, fixtures, and heavy fabrication assemblies. The partially threaded shank provides a bearing surface in the clearance hole, which improves shear resistance. The alloy steel construction supports high clamping loads and tensile strength requirements. The black oxide coating provides mild rust inhibition and is commonly used in controlled shop environments or where parts will be further coated or lubricated after assembly.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8-11 UNC coarse thread for reliable engagement in standard tapped holes\u003c\/li\u003e\n  \u003cli\u003e12-inch length under head accommodates deep-reach and long-grip fastening applications\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank improves shear load distribution in clearance holes\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch hex socket drive compatible with standard hex keys and socket drive tools\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASME\/ANSI B18.3 and ASTM A574 standards\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance and low-glare surface\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in any application requiring a 5\/8-11 UNC hex socket cap screw conforming to ASME\/ANSI B18.3 and ASTM A574 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist, millwright, or maintenance technician using a calibrated torque wrench and the appropriate 1\/2-inch hex key or socket drive. Ensure the mating tapped hole is clean, free of debris, and properly dimensioned to ASME\/ANSI B18.3 tolerances before installation. Apply a thread lubricant or anti-seize compound as appropriate for the service environment to achieve accurate clamp load. Do not over-torque alloy steel fasteners in blind holes or soft base materials.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-11 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially 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\u003eWeight\u003c\/strong\u003e: 1.08 pounds\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\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: 581667BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51722944414002,"sku":"581667BR","price":39.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/02dc5fd1223a26b4c997cc5296235d7e.jpg?v=1788598270","url":"https:\/\/voomisupply.com\/products\/value-collection-581667br-hex-socket-cap-screw-5-8-11-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
