Manufactured from 18-8 stainless steel with a bright, uncoated finish, this screw resists corrosion in a wide range of service environments. The hex socket drive allows for high torque application in tight spaces using a standard hex key. At 1\/4 inch under-head length and a head height of 0.046 inches, it is well suited for assemblies where clearance and head projection must be minimized. Meets ANSI\/ASME B18.3 dimensional standards and carries a 3A thread fit class for close-tolerance installations. Installed by machinists, maintenance technicians, and assembly professionals across industrial and commercial settings.\u003c\/p\u003e\n\u003cp\u003eThis screw is used in light-duty mechanical assemblies, electronic enclosures, instrument panels, and precision equipment where a 2-56 UNC thread form is specified. The button head profile distributes clamping load over a wider bearing area compared to a flat or pan head, making it a common choice in sheet metal and thin-panel assemblies. The 18-8 stainless steel construction makes it appropriate for indoor and mildly corrosive outdoor environments. Minimum order quantity is 100 pieces per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eButton head with hex socket drive for low-profile, high-torque fastening\u003c\/li\u003e\n  \u003cli\u003e18-8 stainless steel construction provides corrosion resistance in a wide range of environments\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — no added coating thickness to affect fit in close-tolerance holes\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI\/ASME B18.3 fastener standard\u003c\/li\u003e\n  \u003cli\u003e3A thread fit class ensures accurate thread engagement for precision assemblies\u003c\/li\u003e\n  \u003cli\u003eRight-hand UNC thread direction, standard for general mechanical use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use fastener for any assembly specifying a 2-56 UNC button socket cap screw per ANSI\/ASME B18.3.\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 or hex driver bit. Ensure mating threads are clean and free of debris before driving to prevent galling, which is a common risk with stainless steel fasteners. Do not over-torque — 18-8 stainless can gall and seize if driven beyond its yield point. Follow the assembly drawing or equipment service manual for the specified torque value for this thread size.\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 Fit Class\u003c\/strong\u003e: 3A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Button\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex Socket\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.046 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 18-8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ANSI\/ASME B18.3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.001 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: R63061643\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51716048617778,"sku":"R63061643","price":589.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dbd8ab518686ed183ad487b60ee71fb3.jpg?v=1788521587","url":"https:\/\/voomisupply.com\/products\/value-collection-r63061643-button-socket-cap-screw-2-56","provider":"Voomi Supply","version":"1.0","type":"link"}
