It features a 2-56 UNC thread size with a 1 inch length under the head and is partially threaded. The 5\/64 inch hex drive accepts a standard Allen key or hex bit driver. Constructed from alloy steel with a black oxide finish, it provides moderate corrosion resistance and reduces light reflection in applications where that matters. This screw meets ASME\/ANSI B18.3 and ASTM A574 standards, making it suitable for demanding industrial and precision mechanical applications. It is typically installed by machinists, maintenance technicians, and assembly professionals.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for use in light-duty mechanical assemblies, instrument housings, jigs, fixtures, and machine components where a low-profile socket head fastener is required. The 2-56 UNC thread is a fine-pitch, small-diameter fastener commonly used in precision equipment, electronics enclosures, and tooling applications. The partial threading allows for controlled clamping and is standard practice for socket cap screws of this length.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2-56 UNC thread size for precision small-diameter fastening applications\u003c\/li\u003e\n  \u003cli\u003e1 inch length under head with partial threading for controlled clamping\u003c\/li\u003e\n  \u003cli\u003e5\/64 inch hex socket drive compatible with standard Allen keys and hex bit drivers\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 mechanical requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides moderate corrosion resistance and low-reflectance appearance\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 accepting a 2-56 UNC partially threaded socket cap screw with a 1 inch length under head.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a calibrated 5\/64 inch hex key or hex bit driver. Ensure the mating threaded hole is clean and correctly tapped to 2-56 UNC specification before installation. De-energize or power down any equipment before servicing fasteners on live assemblies. Do not exceed the torque capacity appropriate for a 2-56 alloy steel fastener to avoid thread stripping or screw failure.\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: 1 inch\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: 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\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\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: 581051PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691084644658,"sku":"581051PR","price":9410.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e3bed4a4fa44fb415fb4e64c8ccb7f1a.jpg?v=1788280160","url":"https:\/\/voomisupply.com\/products\/value-collection-581051pr-hex-socket-cap-screw-2-56-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
