Built from high-speed steel with a bright, uncoated finish, this tap produces 12-56 UNS right-hand threads to a 3B class of fit. The plug chamfer — typically 3 to 5 threads of lead — makes it suitable for starting in a hole and progressing through most of the threading operation. At 2.375 inches overall length with 4 flutes, it is sized for use in standard tapping chucks, drill presses, and manual tap handles.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for threading operations in metalworking, maintenance, and fabrication environments. The 12-56 UNS designation places it in the Unified National Special thread series, a coarser-than-standard pitch used in applications where a 12-28 or 12-32 pitch is not suitable. Machinists, toolroom technicians, and industrial maintenance professionals typically reach for this tap when working with instrument hardware, specialty fasteners, or repair applications requiring the 12-56 thread form. It is appropriate for use in ferrous and non-ferrous metals within the capacity of the high-speed steel construction.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e12-56 UNS thread form with right-hand direction and 3B class of fit for standard tolerance threading\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer provides a gradual lead-in, suitable for through-hole and moderately deep blind-hole applications\u003c\/li\u003e\n  \u003cli\u003e4-flute straight design channels chips back along the flutes — best suited for through-holes or materials that produce short chips\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction withstands the heat generated during threading in steel, aluminum, and similar materials\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish allows easy visual inspection of tool condition and edge wear\u003c\/li\u003e\n  \u003cli\u003eH2 thread limit designates a close-tolerance ground thread for consistent fit with mating 3B components\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-style replacement or stock tap for any application requiring a 12-56 UNS plug tap in high-speed steel with an H2 thread limit and 3B class of fit.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eTapping operations should be performed by a qualified machinist or toolroom technician following established speeds and feeds for the workpiece material and tap size. Always use an appropriate tapping fluid or cutting oil to extend tool life and produce cleaner threads. Secure the workpiece firmly before starting and ensure the tap is aligned perpendicular to the hole to prevent tap breakage. Back out the tap periodically to clear chips and reduce the risk of jamming, particularly in deeper holes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 12-56\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNS (Unified National Special)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 3B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOversize\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\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: JY4838801\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51698477891890,"sku":"JY4838801","price":55.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/219cdfe5b2d0bf4342142019ba807b1e.jpg?v=1788363501","url":"https:\/\/voomisupply.com\/products\/value-collection-jy4838801-straight-flute-tap-12-56-uns","provider":"Voomi Supply","version":"1.0","type":"link"}
