Sized at 2-56 UNC with a 3\/4-inch length under head, this fastener is fully threaded and manufactured from alloy steel with a black oxide coating. Hardness is rated at 36 to 43 HRC, making it suitable for moderate-to-high-strength fastening in tight assemblies. Conforming to ANSI\/ASME B18.3 and ASTM F835 standards, it is a reliable choice for engineers, machinists, and maintenance technicians working with small-diameter threaded assemblies.\u003c\/p\u003e\u003cp\u003eThis screw is used in applications where a standard socket head cap screw would protrude too far or where head clearance is limited. The button head profile reduces interference in recessed or close-tolerance assemblies. Common install scenarios include light-duty mechanical assemblies, instrumentation panels, enclosures, and fixtures where a flush or near-flush fastener surface is required. The black oxide finish provides mild corrosion resistance and reduces light reflection in optical or electronic environments. Minimum order quantity is 100 pieces per order.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eButton head, low-profile design for clearance-critical assemblies\u003c\/li\u003e\n\u003cli\u003eHex socket (Allen) drive for precise torque application in confined spaces\u003c\/li\u003e\n\u003cli\u003eFully threaded 2-56 UNC thread form with Class 3A thread fit\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction rated 36 to 43 HRC hardness\u003c\/li\u003e\n\u003cli\u003eBlack oxide coating for mild corrosion resistance and reduced reflectivity\u003c\/li\u003e\n\u003cli\u003eConforms to ANSI\/ASME B18.3 and ASTM F835 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 2-56 UNC button socket cap screw for use in any application or assembly that accepts ANSI\/ASME B18.3 compliant fasteners of this thread size and length.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a hex socket (Allen key) driver sized for the 2-56 button head specification. Ensure mating threads are clean and free of debris before driving. Apply fastener only to tapped holes conforming to 2-56 UNC Class 3A or compatible thread standards. Avoid over-torquing, as the small diameter and button head style have lower torque capacity compared to standard socket head cap screws of the same thread size.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eLength Under Head\u003c\/strong\u003e: 3\/4 inches\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\u003eHead Height\u003c\/strong\u003e: 0.0460 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\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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 701015PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51701700198706,"sku":"701015PR","price":3417.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ffda7ecfa587d5e33935a0d339539e07.jpg?v=1788403983","url":"https:\/\/voomisupply.com\/products\/value-collection-701015pr-button-socket-cap-screw-2-56","provider":"Voomi Supply","version":"1.0","type":"link"}
