It features a 1\/4-20 UNC thread profile with a plug chamfer, making it suitable for starting in a hole that already has a partial thread or for general-purpose through-hole tapping. Made from high speed steel (HSS) with a bright, uncoated finish, this tap operates with a right-hand thread direction and carries an H3 thread limit. Two flutes channel chips forward ahead of the tap, keeping the cutting zone clear and reducing the risk of re-cutting chips. It is a standard choice for machinists and maintenance technicians working in steel, aluminum, and similar materials.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for through-hole applications in production and maintenance environments. The plug chamfer provides a moderate lead-in of several thread starts, balancing ease of entry with thread-cutting efficiency. The 1\/4-20 UNC thread is one of the most common fastener threads in North American manufacturing and repair work, making this tap useful across a wide range of general machining, fabrication, and mechanical assembly tasks. A Class 3B fit designation indicates tolerance for standard precision thread engagement. No coolant-through capability is present, so conventional cutting fluid applied externally is the appropriate lubrication method.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-20 UNC thread profile with plug chamfer for through-hole tapping\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability across a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit with Class 3B fit for standard precision thread tolerance\u003c\/li\u003e\n  \u003cli\u003e2-flute spiral point design pushes chips forward to keep the flutes clear\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, bright uncoated finish, no coolant-through required\u003c\/li\u003e\n  \u003cli\u003e1 inch thread length provides adequate engagement depth for typical 1\/4-20 applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/4-20 UNC plug spiral point tap suitable for use in through-hole tapping operations on common engineering materials including steel, cast iron, aluminum, and brass.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap is installed using a standard tap wrench, tapping handle, or machine spindle; verify the driver fits the tap shank squarely before applying torque. Use an appropriate cutting fluid or tapping compound for the workpiece material to extend tap life and improve thread finish. Ensure the pilot hole is drilled to the correct size for 1\/4-20 UNC before tapping. Remove the tap periodically to clear chips when working in deeper holes, even though the spiral point design advances chips forward in through-hole applications.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 3B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel (HSS)\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\u003eWeight\u003c\/strong\u003e: 0.06 pounds\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: MSC-04540209\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694189904178,"sku":"MSC-04540209","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c02266608bf191570c4ed24b13aad006.jpg?v=1788321470","url":"https:\/\/voomisupply.com\/products\/value-collection-msc-04540209-spiral-point-tap-1-4-20-unc-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
