Manufactured from high speed steel with a bright, uncoated finish, this tap delivers reliable thread-cutting performance in ferrous and non-ferrous metals where hand tapping is required. The plug chamfer style — with a moderate lead-in of approximately 3 to 5 threads — makes it suitable for most general-purpose through-hole work. Thread fit is held to Class 3B tolerance at an H4 thread limit, providing a close-tolerance fit appropriate for precision assemblies. Overall length is 4 inches.\u003c\/p\u003e\n\u003cp\u003eThis tap is used in machine shops, maintenance and repair operations, and field service environments where 1-3\/8-24 UNS threads must be cut or restored by hand. The UNS thread standard indicates a Unified National Special pitch, making this tap appropriate for non-standard pitch applications that fall outside the common UNC and UNF series. It is installed by machinists and skilled trade professionals using a standard tap wrench. Right-hand threading direction requires standard clockwise rotation during cutting.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-3\/8-24 UNS thread size with right-hand cutting direction\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer provides a moderate lead-in for general through-hole tapping\u003c\/li\u003e\n  \u003cli\u003e6-flute design for improved chip distribution and thread finish\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability across a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — compatible with most cutting fluids\u003c\/li\u003e\n  \u003cli\u003eClass 3B fit at H4 thread limit for close-tolerance thread production\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for hand tapping 1-3\/8-24 UNS threaded holes in applications requiring a Class 3B, H4 thread limit fit.

Always ensure the workpiece is securely fixtured and apply a suitable cutting fluid for the workpiece material before beginning the tapping operation. Back the tap out periodically to clear chips and prevent tap breakage, especially in deeper holes. Do not apply excessive torque; high speed steel taps can fracture if forced.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-3\/8-24\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\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\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: H4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Straight\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\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: JY4872248\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720989671730,"sku":"JY4872248","price":325.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/60715dc3f3539dc222262dfeefab8466.jpg?v=1788571951","url":"https:\/\/voomisupply.com\/products\/value-collection-jy4872248-hand-tap-1-3-8-24-uns-plug","provider":"Voomi Supply","version":"1.0","type":"link"}
