Manufactured from high speed steel (HSS) with a bright, uncoated finish, it features a 4-flute straight flute geometry and a right-hand thread direction. The H3 thread limit ensures consistent Class 3B tolerance fits for close-tolerance fastener applications. With an overall length of 2.375 inches, this tap is suited for hand-tapping operations in machine shops, maintenance environments, and production work where controlled thread depth at the bottom of a hole is required.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for use in threading operations on ferrous and non-ferrous materials where a UNS 10-28 thread form is specified. The bottoming chamfer style — typically 1 to 2 threads of lead — allows the tap to thread as close to the bottom of a blind hole as possible, making it appropriate for applications where thread engagement depth is limited. It is commonly used by machinists, toolmakers, and maintenance technicians working with small fastener assemblies in light-duty mechanical and structural components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBottoming chamfer cuts full threads to the bottom of blind holes\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides hardness and wear resistance for hand-tapping\u003c\/li\u003e\n  \u003cli\u003e4-flute straight flute design for chip control in through and blind hole applications\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for use with cutting fluids across a range of materials\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit maintains Class 3B tolerance for close-tolerance thread fits\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction matches standard fastener orientation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard tap wrenches and T-handle drivers sized for small-shank hand taps.

Before tapping, ensure the correct drill size for a 10-28 thread has been used and the workpiece is securely fixtured. Apply an appropriate cutting fluid for the material being tapped to extend tool life and improve thread quality. Use a bottoming tap only as the final step in a tapping sequence — complete threading with a taper or plug tap first when working in blind 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: Bottoming\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 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\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\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: JY4838298\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51696703013170,"sku":"JY4838298","price":54.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f3ee5400932fd05546221294131b9d7f.jpg?v=1788345391","url":"https:\/\/voomisupply.com\/products\/value-collection-jy4838298-hand-tap-10-28-uns-bottoming-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
