Manufactured from alloy steel with a black oxide coating, this screw delivers corrosion resistance and a clean, low-reflectance finish suited for industrial and mechanical assemblies. The 2-56 UNC thread form and 3\/4 inch length under head make it a reliable choice for small-component assemblies where torque retention and dimensional accuracy are critical. It is driven by a 5\/64 inch hex key and is fully threaded along its length. This fastener conforms to ASME\/ANSI B18.3 and ASTM A574 standards, ensuring consistent mechanical properties across production runs.\u003c\/p\u003e\n\u003cp\u003eThis screw is used in light mechanical assemblies, instrumentation, electronics enclosures, and precision equipment where a small-diameter, fine-thread fastener is required. The 2-56 UNC thread is common in miniaturized hardware, PCB standoff mounting, and tight-tolerance metal components. It is appropriate for both original equipment manufacturing and MRO replacement applications. Installers typically source these in quantity lots of 100 or more due to the small size and high usage rates in production environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2-56 UNC thread for fine-pitch, high-retention fastening in small assemblies\u003c\/li\u003e\n  \u003cli\u003eFully threaded shank maximizes thread engagement along the entire 3\/4 inch length under head\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 mechanical requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance and reduces surface reflectance\u003c\/li\u003e\n  \u003cli\u003e5\/64 inch hex drive allows precise torque application with standard hex key tooling\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME\/ANSI B18.3 dimensional standard\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 2-56 UNC hex socket cap screw for use in any application requiring an ASME\/ANSI B18.3 compliant fastener of this thread size and drive type.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a calibrated 5\/64 inch hex key or T-handle driver. Ensure mating threads are clean and free of debris before driving. Power down any equipment completely before performing fastener work on electrical enclosures or instrumentation panels. Do not over-drive; small-diameter alloy screws can be damaged by excessive torque applied with power tools without a torque-limiting clutch.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 2-56 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3\/4 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: 5\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Fully 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\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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\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: 581047PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51717125177650,"sku":"581047PR","price":5561.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c106e799ae00f019ad43356937dde456.jpg?v=1788536031","url":"https:\/\/voomisupply.com\/products\/value-collection-581047pr-hex-socket-cap-screw-2-56-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
