Made from high speed steel with a bright uncoated finish, this tap delivers consistent thread formation in ferrous and non-ferrous metals. It carries a Class 3B fit designation and an H3 thread limit, producing tight-tolerance threads suited to precision fastener applications. The 4-flute straight flute geometry provides stable chip evacuation in through-hole and short blind-hole work. With an overall length of 3-19\/32 inches, it fits standard tap wrenches used by machinists and maintenance technicians.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for hand tapping operations where a bottoming chamfer is required to thread as close to the bottom of a blind hole as possible. It follows the UNS thread standard at 9\/16-20, making it appropriate for applications that call for fine-pitch unified thread forms in that size range. Typical use cases include repair threading, fixture fabrication, and production hand-tapping in machine shops, maintenance facilities, and industrial service environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBottoming chamfer allows threading to the base of blind holes\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction resists heat and wear during hand tapping\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for use with standard cutting oils and lubricants\u003c\/li\u003e\n  \u003cli\u003eClass 3B fit with H3 thread limit for tight-tolerance thread production\u003c\/li\u003e\n  \u003cli\u003e4-flute straight flute design provides rigidity and chip control\u003c\/li\u003e\n  \u003cli\u003eOverall length of 3-19\/32 inches compatible with standard tap wrenches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style hand tap for 9\/16-20 UNS right-hand threaded applications requiring a bottoming chamfer and Class 3B fit.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap is installed by machinists or maintenance technicians using a standard tap wrench. Always apply appropriate cutting fluid before and during tapping to reduce friction and extend tool life. Ensure the workpiece is securely fixtured and the tap is aligned perpendicular to the hole before applying torque. A starter or plug tap should be used first when threading from scratch in a blind hole before finishing with this bottoming tap.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 9\/16-20\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 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: 3-19\/32 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: JY4845202\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51718135054642,"sku":"JY4845202","price":71.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/53fa7ae1b89b0adc20b9565797f5a7f0.jpg?v=1788550182","url":"https:\/\/voomisupply.com\/products\/value-collection-jy4845202-hand-tap-9-16-20-uns-bottoming","provider":"Voomi Supply","version":"1.0","type":"link"}
