Built from high-speed steel (HSS) with a bright, uncoated finish, it produces 3\/8-16 UNC threads to a 3B class of fit using a taper chamfer entry. The taper chamfer distributes cutting load gradually across the leading threads, making this tap well suited for through-hole applications where alignment is straightforward. With a thread limit of H3 and four flutes, it delivers consistent thread geometry across production and maintenance work. The overall length is 2-15\/16 inches with a 1-1\/4 inch thread length, and the tool weighs 0.09 pounds.\u003c\/p\u003e\n\u003cp\u003eThis tap is used in general machining, fabrication shops, and maintenance environments where 3\/8-16 UNC threads are required. Typical applications include threading through-holes in structural steel, machine frames, brackets, and equipment housings. The right-hand thread direction is standard for the vast majority of fastener applications. It is sized for use in a standard tap handle or machine tapping setup and is appropriate for both manual and low-speed machine tapping operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-16 UNC thread size with 3B class of fit for standard tolerance internal threads\u003c\/li\u003e\n  \u003cli\u003eTaper chamfer distributes cutting force gradually, ideal for through-hole tapping\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides durability across a range of ferrous workpiece materials\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit ensures consistent fit with standard 3\/8-16 UNC fasteners\u003c\/li\u003e\n  \u003cli\u003eFour-flute design offers chip clearance and stable cutting geometry\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, bright uncoated finish, no coolant-through requirement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard service tap for any application requiring 3\/8-16 UNC internal threads; fits standard tap handles and collet-style machine tap holders sized for 3\/8 inch shank taps.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eMachinists and maintenance technicians should secure the workpiece firmly before tapping to prevent movement during thread cutting. Apply cutting fluid appropriate for the workpiece material to reduce heat and extend tool life. Use a calibrated tap handle or tapping head to maintain axial alignment and avoid tap breakage. Back off periodically to clear chips, especially in deeper holes, and never force the tap against hard resistance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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\u003eChamfer Type\u003c\/strong\u003e: Taper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 2.9375 inches\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.09 pounds\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: MSC-04472189\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51689273360690,"sku":"MSC-04472189","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f47a92032ccaf0de5e54eb401079f230.jpg?v=1788256629","url":"https:\/\/voomisupply.com\/products\/value-collection-msc-04472189-straight-flute-tap-3-8-16-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
