Manufactured from high speed steel with a bright uncoated finish, this tap is built for threading operations in a range of common work materials. The taper chamfer — spanning several threads at the lead — guides the tap into the hole progressively, distributing cutting load across multiple teeth. With 4 flutes and an H2 thread limit, it holds tight tolerances suitable for standard fastener fits. Overall length is 2-15\/16 inches with a 1-1\/4 inch thread length. Machinists, toolroom technicians, and maintenance tradespeople use this tap for hand-threading operations in production and repair settings.\u003c\/p\u003e\u003cp\u003eThis tap is suited for threading 3\/8-16 UNC holes in ferrous and non-ferrous metals, plastics, and similar machinable materials. The taper chamfer style is particularly effective when starting threads in a new hole, making it a first-tap choice in a taper-plug-bottoming sequence. It fits standard tap wrench drives and is commonly used in bench work, field maintenance, and light machine shop applications where hand tapping is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/8-16 UNC thread form for compatibility with standard inch-series fasteners\u003c\/li\u003e\n\u003cli\u003eTaper chamfer distributes cutting load across the lead threads for easier starting\u003c\/li\u003e\n\u003cli\u003eH2 thread limit for close-tolerance standard fits\u003c\/li\u003e\n\u003cli\u003e4 straight flutes for chip clearance in through-hole and shallow blind-hole applications\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction provides hardness and wear resistance for hand tapping\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish — no coating buildup that could affect thread tolerance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard hand tap for use in any application requiring 3\/8-16 UNC right-hand internal threads.

Always drill the correct tap drill size for 3\/8-16 UNC before tapping and ensure the hole is clear of chips. Apply cutting fluid appropriate to the work material to reduce friction and extend tap life. Reverse the tap periodically to break chips and prevent binding, especially in deeper holes.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eThread Direction\u003c\/strong\u003e: Right Hand\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\u003eFlute Style\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H2\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\u003eThread Length\u003c\/strong\u003e: 1-1\/4 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: 0.08 pounds\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: MSC-04462180\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51690320789810,"sku":"MSC-04462180","price":17.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9cc2f5b185dd08d9426230299eda1ab0.jpg?v=1788268729","url":"https:\/\/voomisupply.com\/products\/value-collection-msc-04462180-hand-tap-3-8-16-unc-taper","provider":"Voomi Supply","version":"1.0","type":"link"}
