This partially threaded fastener features a 2-56 UNC thread with an 82-degree flat head profile and an internal hex socket drive. Manufactured from alloy steel with a black oxide finish, the 721020PR provides corrosion resistance and reduced light reflection in close-tolerance assemblies. It measures 1 inch in overall length and weighs approximately 0.01 pounds. Installation requires a standard hex key or Allen wrench sized for #2 socket cap screws.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for light mechanical assemblies, instrument panels, electronics enclosures, and precision machine components where a low-profile flush-mounted fastener is needed. The black oxide finish makes it a common choice in applications requiring minimal surface glare or a uniform dark appearance. The 2-56 UNC thread size is typical in miniature and instrument-grade fastening scenarios encountered by machinists, assembly technicians, and equipment repair professionals.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e82-degree flat head profile seats flush in standard countersunk holes\u003c\/li\u003e\n  \u003cli\u003eInternal hex socket drive for precise torque application in confined spaces\u003c\/li\u003e\n  \u003cli\u003e2-56 UNC thread form per ASME\/ANSI B18.3 and ASTM F835\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank for positive clamping in through-hole applications\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction with black oxide finish for corrosion and glare resistance\u003c\/li\u003e\n  \u003cli\u003e1 inch overall length accommodates moderate-depth fastening needs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series flat socket cap screw conforming to ASME\/ANSI B18.3 and ASTM F835, suitable for any application calling for a #2-56 UNC partially threaded flat socket cap screw in alloy steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or assembly technicians using a properly sized hex key. The mating countersink should be machined to an 82-degree included angle to ensure correct head seating. Power down or de-energize any equipment before fastener replacement in electrical or electronic assemblies. Avoid overtightening, as the small thread size has limited torque capacity.\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\u003eLength\u003c\/strong\u003e: 1 inch (overall length)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: 82-degree Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex Socket\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially Threaded\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\u003eFastener Standard\u003c\/strong\u003e: ASME\/ANSI B18.3, ASTM F835\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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: 721020PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694522433842,"sku":"721020PR","price":6532.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d4e14fa2f3ded20955a633a001935bb0_befaa9c0-ab42-429b-a895-6102bea31af1.jpg?v=1788324999","url":"https:\/\/voomisupply.com\/products\/value-collection-721020pr-flat-socket-cap-screw-2-56-1-in","provider":"Voomi Supply","version":"1.0","type":"link"}
