Manufactured from alloy steel with a black oxide finish, this fastener meets ASME\/ANSI B18.3 and ASTM A574 standards. It features a 2-56 UNC thread size, a 7\/32 inch length under head, and a 5\/64 inch hex drive. The fully threaded shank provides maximum thread engagement along the entire fastener length. Maintenance technicians, machinists, and assembly professionals install this type of screw where a flush or recessed head profile and socket drive access are required in tight clearance situations.\u003c\/p\u003e\u003cp\u003eThis screw is suited for light-duty mechanical assemblies, instrument panels, electronic enclosures, and precision equipment where a small-diameter, fine-thread fastener is specified. The 2-56 UNC designation places it in the finer end of the unified inch coarse series, making it appropriate for thin-material applications and components where thread stripping risk must be minimized. It is sold in minimum order quantities of 100 pieces per the supplier specification.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlloy steel construction meets ASTM A574 mechanical requirements for socket cap screws\u003c\/li\u003e\n\u003cli\u003eBlack oxide coating provides mild corrosion resistance and reduces light reflection\u003c\/li\u003e\n\u003cli\u003eFully threaded shank maximizes thread engagement for the 7\/32 inch body length\u003c\/li\u003e\n\u003cli\u003e5\/64 inch hex drive accepts standard hex keys and socket bits\u003c\/li\u003e\n\u003cli\u003eConforms to ASME\/ANSI B18.3 dimensional standards for socket head cap screws\u003c\/li\u003e\n\u003cli\u003e2-56 UNC thread form compatible with standard unified inch tapped holes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard ASME\/ANSI B18.3 hex socket cap screw for use in any application specifying a 2-56 UNC fully threaded socket head cap screw with a 7\/32 inch length under head.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall using a calibrated 5\/64 inch hex key or T-handle driver; do not substitute an undersized key as this risks rounding the drive recess. Verify the mating tapped hole is clean and dimensionally correct for 2-56 UNC thread form before installation. De-energize and de-pressurize any assembly before servicing fasteners on live mechanical or electrical equipment. Follow applicable torque guidance from the equipment manufacturer or relevant industry standards for the 2-56 size class.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 7\/32 inches\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\u003eThreading\u003c\/strong\u003e: Fully 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 A574\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: 581040PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51690312466738,"sku":"581040PR","price":6855.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/72c24d1db6e5a0a37b14b4eb23ca04bc.jpg?v=1788268574","url":"https:\/\/voomisupply.com\/products\/value-collection-581040pr-hex-socket-cap-screw-2-56-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
