It features a 2-56 UNC thread, a 1\/8-inch length under the head, and a hex socket drive. Manufactured from alloy steel with a black oxide coating, it delivers corrosion resistance and a clean, low-profile appearance. Hardness is rated at 36-43 HRC, and the thread fit class is 3A, meeting ANSI\/ASME B18.3 and ASTM F835 standards. The fully threaded shank ensures consistent grip across the entire fastened length. This screw is installed by machinists, assembly technicians, and trades professionals working with small-gauge mechanical assemblies.\u003c\/p\u003e\n\u003cp\u003eThis fastener is suited for applications requiring a low-profile head with high torque-transmission capability through a hex socket drive. Common uses include precision instrument assemblies, electronic enclosures, small mechanical fixtures, and other applications where a standard hex head would interfere with mating components. The black oxide finish makes it a practical choice in environments where light corrosion inhibition and a non-reflective surface are preferred. This item is sold individually but requires a minimum order quantity of 100 pieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2-56 UNC fully threaded alloy steel construction for consistent thread engagement\u003c\/li\u003e\n  \u003cli\u003eButton head profile provides low clearance over mating surfaces\u003c\/li\u003e\n  \u003cli\u003eHex socket drive allows torque application in confined spaces\u003c\/li\u003e\n  \u003cli\u003eBlack oxide coating for light corrosion resistance and non-reflective finish\u003c\/li\u003e\n  \u003cli\u003eHardness of 36-43 HRC meets ASTM F835 mechanical requirements\u003c\/li\u003e\n  \u003cli\u003eThread fit class 3A per ANSI\/ASME B18.3 for precise fitment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 2-56 UNC button socket cap screw conforming to ANSI\/ASME B18.3 and ASTM F835, suitable for use in any application requiring a right-hand, 3A thread-fit class fastener in this size.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall and remove using the correct hex key or hex socket driver sized for the small-gauge drive recess to avoid rounding. Ensure mating tapped holes are clean and meet the 2-56 UNC thread specification before installation. Follow applicable mechanical or equipment service procedures when fastening into precision assemblies. Do not exceed the torque rating for the assembly material, and verify the fully threaded shank engages fully within the tapped depth.\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Fit Class\u003c\/strong\u003e: 3A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Button\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.0460 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex Socket\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\u003eHardness\u003c\/strong\u003e: 36-43 HRC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ANSI\/ASME B18.3, ASTM F835\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: 701301PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51711974539570,"sku":"701301PR","price":3991.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fd87f392739af529f4c5744d64a6477b.jpg?v=1788482112","url":"https:\/\/voomisupply.com\/products\/value-collection-701301pr-button-socket-cap-screw-2-56","provider":"Voomi Supply","version":"1.0","type":"link"}
