Built from high speed steel (HSS) with a bright uncoated finish, this tap features three flutes and a plug chamfer that progressively engages the workpiece, pushing chips forward through the hole rather than packing them behind the cutting edge. The H3 thread limit designates a standard tolerance class suited for general-purpose threading where consistent fit and dimensional accuracy are required. It is sized for 3\/8-16 UNC threads, one of the most common unified coarse thread specifications used in North American fastening applications.\u003c\/p\u003e\n\u003cp\u003eThis tap is used in machine shop, maintenance, and field-service applications wherever 3\/8-16 UNC through-holes need to be threaded in ferrous and non-ferrous materials. It is appropriate for use in drill presses, CNC machining centers, tapping machines, or hand-held power tools equipped with a proper tap holder. Typical users include machinists, tool-and-die technicians, millwrights, and industrial maintenance professionals working with steel, aluminum, and similar machinable materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-16 UNC thread size for standard coarse-thread through-hole applications\u003c\/li\u003e\n  \u003cli\u003eSpiral point design pushes chips forward, reducing chip packing in through-holes\u003c\/li\u003e\n  \u003cli\u003e3-flute geometry provides a balance of chip clearance and cutting edge strength\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer allows progressive thread engagement for machine or hand tapping\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction offers durability across a range of machinable materials\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit ensures consistent tolerance for general-purpose thread fits\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose spiral point plug tap for 3\/8-16 UNC through-hole threading.

Ensure the workpiece is securely clamped and the pilot hole is drilled to the correct tap drill diameter for 3\/8-16 UNC before threading. Use appropriate cutting fluid for the workpiece material to extend tap life and improve thread finish. Never force a tap that has stopped turning freely, as this can result in tap breakage in the workpiece.\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\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel (HSS)\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: H3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOversize\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: BDNA-20662\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51689145106738,"sku":"BDNA-20662","price":37.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7a67b2fa58dd5f1e78dc8ae39bea924f.jpg?v=1788255224","url":"https:\/\/voomisupply.com\/products\/value-collection-bdna-20662-spiral-point-tap-3-8-16-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
