The set includes 12 taps covering 1\/4-20 through 9\/16-32 and 14 hex dies covering 1\/4-20 through 5\/8-18, all manufactured from carbon steel. It is a practical shop tool for trade professionals who need to chase damaged threads, run new threads on rod or pipe stubs, or fabricate field repairs on threaded fasteners. The plastic storage case keeps pieces organized and protected between uses.\u003c\/p\u003e\u003cp\u003eThis set suits general mechanical work encountered by HVAC technicians, plumbers, electricians, and other trade pros who work with fractional fasteners. It covers the most common UNC coarse and UNF fine thread sizes found on equipment hardware, brackets, valve bodies, and field-fabricated supports. The hex die profile allows use with a standard wrench where a die stock is not available, adding flexibility in tight service locations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e26-piece set includes 12 taps and 14 hex dies\u003c\/li\u003e\n\u003cli\u003eTap range: 1\/4-20 through 9\/16-32 (UNC and UNF)\u003c\/li\u003e\n\u003cli\u003eDie range: 1\/4-20 through 5\/8-18 (UNC and UNF)\u003c\/li\u003e\n\u003cli\u003eCarbon steel construction for both taps and dies\u003c\/li\u003e\n\u003cli\u003eHex die shape compatible with standard wrenches\u003c\/li\u003e\n\u003cli\u003eIncludes 7 SAE coarse dies for common fastener sizes\u003c\/li\u003e\n\u003cli\u003eOrganized plastic storage case included\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on fractional inch fasteners and threaded rod in UNC and UNF thread standards.

Always clear chips frequently during tapping to prevent tap breakage, particularly in blind holes. Taps and dies should be turned with steady, controlled pressure using a proper tap wrench or die stock, or a wrench sized to the hex die flats. Inspect threads after cutting with the mating fastener before assembly.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 26\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Taps\u003c\/strong\u003e: 12\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Tap Thread Size\u003c\/strong\u003e: 1\/4-20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Tap Thread Size\u003c\/strong\u003e: 9\/16-32\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Die Thread Size\u003c\/strong\u003e: 1\/4-20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Die Thread Size\u003c\/strong\u003e: 5\/8-18\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC, UNF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDie Shape\u003c\/strong\u003e: Hex\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdjustable Die\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTap Material\u003c\/strong\u003e: Carbon Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDie Material\u003c\/strong\u003e: Carbon Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCase Type\u003c\/strong\u003e: Plastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.5 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: LANG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 2581M\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LANG","offers":[{"title":"Default Title","offer_id":51539553452338,"sku":"2581M","price":124.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9bc5a0d3d6986b55801197ca5eb42f9b.jpg?v=1785842928","url":"https:\/\/voomisupply.com\/products\/lang-2581m-tap-die-set-unc-unf-carbon-steel-26-pc","provider":"Voomi Supply","version":"1.0","type":"link"}
