Built from high speed steel (HSS) with a bright uncoated finish, this tap delivers consistent thread formation in ferrous and non-ferrous metals, plastics, and similar workpiece materials. The plug chamfer style features a gradual lead-in of approximately 3 to 5 threads, making it suitable for through-hole tapping where the tap can pass completely through the workpiece. The 4-flute straight flute geometry provides stability and reliable chip control in standard drilling and tapping operations. Overall length is 2.375 inches, fitting standard tap handles and machine tool collets used in machining and maintenance applications.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for machinists, maintenance technicians, and toolroom professionals performing thread repair or new thread creation in through-holes. The 10-28 UNS thread designation covers unified national special applications where 10-28 threading is specified. The Class 3B fit tolerance produces tight, accurate internal threads appropriate for close-tolerance assemblies. The H3 thread limit provides a controlled oversize tolerance to account for slight tap wear during cutting, making it a practical choice for production and job-shop environments alike.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e10-28 UNS thread form cuts unified national special internal threads to Class 3B fit\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer (3 to 5 thread lead) suited for through-hole tapping applications\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides hardness and wear resistance across common workpiece materials\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish allows direct inspection of tool condition and is compatible with standard cutting fluids\u003c\/li\u003e\n  \u003cli\u003e4-flute straight flute design delivers stable cutting geometry and consistent chip evacuation\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit compensates for normal tool wear to maintain thread accuracy over multiple uses\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard hand tap for use in through-hole tapping operations requiring a 10-28 UNS thread form.

Secure the workpiece fully before tapping to prevent movement. Apply an appropriate cutting fluid for the workpiece material to reduce heat buildup and extend tool life. Advance the tap in short increments and periodically reverse direction to break chips and prevent tap breakage, particularly in deeper through-holes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 10-28\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNS\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: H3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Style\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\u003eOverall Length\u003c\/strong\u003e: 2.375 inches\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\u003ePackage Quantity\u003c\/strong\u003e: 1\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: JY4838280\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693566886194,"sku":"JY4838280","price":55.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0c800ddf86774ed3d7fd5c0746f02917.jpg?v=1788314178","url":"https:\/\/voomisupply.com\/products\/value-collection-jy4838280-hand-tap-10-28-uns-plug-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
