Built from high speed steel with a bright, uncoated finish, this tap offers solid wear resistance for general-purpose threading applications. The plug chamfer — typically 3 to 5 threads of lead — makes it suitable for threading through-holes and providing a smooth entry into partially blind holes. With 4 flutes and a right-hand thread direction, it follows standard hand-tapping practice and works with conventional tap wrenches and tapping fixtures. Overall length is 5.125 inches, providing adequate clearance in most bench and machine setups.\u003c\/p\u003e\u003cp\u003eThis tap is suited for maintenance, repair, and production threading operations where UNEF fine-thread pitch is specified. It is commonly used in machine shops, industrial maintenance environments, and precision manufacturing where close tolerances are required. The Class 3B fit designation indicates a tight tolerance thread, appropriate for assemblies demanding accurate thread engagement. Licensed machinists, toolmakers, and maintenance technicians are the primary users of this type of tap.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-1\/16-18 UNEF thread form for fine-pitch internal threading\u003c\/li\u003e\n\u003cli\u003ePlug chamfer provides 3 to 5 thread lead for through-hole and partial blind-hole entry\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction for general-purpose durability across common workpiece materials\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish — no coating to affect thread tolerance or require special handling\u003c\/li\u003e\n\u003cli\u003eClass 3B fit with H4 thread limit for tight-tolerance thread production\u003c\/li\u003e\n\u003cli\u003e4-flute straight-flute geometry compatible with standard hand-tapping technique\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose hand tap for cutting 1-1\/16-18 UNEF right-hand internal threads in accordance with Unified National Extra Fine thread standards.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap is installed by hand or with a standard tap wrench; ensure the workpiece is securely fixtured before starting the thread. Always use a cutting fluid or tapping compound appropriate for the workpiece material to reduce friction and improve thread finish. Align the tap perpendicular to the work surface before applying torque to avoid tap breakage or thread misalignment. Follow applicable shop safety procedures and relevant standards for threading operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-1\/16-18\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNEF\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: 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: 5.125 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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: JY4861233\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51707181826354,"sku":"JY4861233","price":155.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4741737951bc6195a8681af8c03b3626.jpg?v=1788438794","url":"https:\/\/voomisupply.com\/products\/value-collection-jy4861233-hand-tap-1-1-16-18-unef","provider":"Voomi Supply","version":"1.0","type":"link"}
