It features a 2-56 UNC thread size with a 5\/32-inch length under the head and is fully threaded from head to tip. The drive is a 5\/64-inch internal hex, requiring an Allen wrench or hex key for installation. Manufactured from alloy steel with a black oxide coating, this fastener provides good tensile strength and moderate corrosion resistance. It is suited for close-tolerance work where a recessed drive head and clean profile are required. Licensed machinists, maintenance technicians, and precision assembly workers are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThis screw is appropriate for use in light mechanical assemblies, instrument panels, jig-and-fixture builds, and small-component mounting where a low-profile socket head and fine UNC threading are necessary. The 2-56 thread is a standard fine fastener size commonly found in electronics enclosures, optical equipment mounts, and precision tooling fixtures. The black oxide finish reduces surface reflectivity and provides light rust inhibition in dry or mildly humid indoor environments. This part is sold individually but requires a minimum order quantity of 100 units per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2-56 UNC thread for precise engagement in fine-threaded tapped holes\u003c\/li\u003e\n  \u003cli\u003e5\/32-inch length under head, fully threaded for maximum thread engagement\u003c\/li\u003e\n  \u003cli\u003e5\/64-inch internal hex drive for use with standard Allen wrenches or hex keys\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction for high tensile strength relative to fastener size\u003c\/li\u003e\n  \u003cli\u003eBlack oxide coating reduces light reflection and provides light corrosion inhibition\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM A574 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-stock hex socket cap screw for applications requiring a 2-56 UNC fully threaded alloy steel fastener with a 5\/64-inch hex drive.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a calibrated 5\/64-inch hex key or Allen wrench; do not use an undersized or worn driver, as this can strip the socket recess at this fastener size. Verify that the mating tapped hole is clean, correctly sized for 2-56 UNC, and free of debris before installation. Apply thread-locking compound if vibration resistance is required, following the compound manufacturer's guidance. Always de-energize or depressurize any assembly before removing or replacing fasteners on active equipment.\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: 5\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull or Partial Threading\u003c\/strong\u003e: Fully Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex (Internal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 5\/64 inches\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: 0.01 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: 581061PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51714137751858,"sku":"581061PR","price":5988.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a3335dab3a96d8e2b023ac2020a53543.jpg?v=1788496744","url":"https:\/\/voomisupply.com\/products\/value-collection-581061pr-hex-socket-cap-screw-2-56-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
