Built from bright-finish high speed steel, this tap features a plug chamfer with 4 flutes and an H11 thread limit, making it well suited for through-hole and moderately deep blind-hole applications. The oversize grind of 0.005 inches accommodates thread tolerance stacking in precision assemblies. Overall length is 2-15\/16 inches. Machinists, toolroom technicians, and maintenance mechanics rely on this configuration for general-purpose hand tapping where consistent thread geometry and tool durability are required.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for hand tapping operations on standard UNF 3\/8-24 threaded holes. The plug chamfer, with its moderate lead-in, makes it appropriate for starting threads in through holes or beginning a threading sequence before a bottoming tap is used. It is commonly applied in metalworking, maintenance and repair, and light fabrication environments where right-hand unified fine threads are specified. The bright uncoated finish is suitable for use with cutting oils and standard tapping fluids across ferrous and non-ferrous workpieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-24 UNF right-hand thread form for unified fine thread applications\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer provides moderate lead-in, suitable for through holes and starting blind holes\u003c\/li\u003e\n  \u003cli\u003eH11 thread limit oversize grind at 0.005 inches for controlled thread tolerance\u003c\/li\u003e\n  \u003cli\u003e4-flute straight flute geometry for chip clearance in general-purpose hand tapping\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction offers durability across a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish compatible with standard cutting oils and tapping fluids\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or supplemental hand tap for 3\/8-24 UNF threaded hole applications in general metalworking, maintenance, and fabrication settings.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eHand tapping should be performed by a machinist or qualified technician using a properly sized tap wrench and appropriate cutting fluid for the workpiece material. Ensure the tap is started perpendicular to the workpiece surface to avoid cross-threading or tap breakage. Back off the tap periodically to break chips, particularly in deeper holes. Do not force the tap if resistance increases suddenly, as high speed steel taps can fracture under excessive torque.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\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\u003eThread Limit\u003c\/strong\u003e: H11\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmount Oversize\u003c\/strong\u003e: 0.005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-15\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\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: JY4742250\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720778350898,"sku":"JY4742250","price":23.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e8109126df08d47643b0f7c28d930f19.jpg?v=1788569043","url":"https:\/\/voomisupply.com\/products\/value-collection-jy4742250-hand-tap-3-8-24-unf-plug-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
