Built from high-speed steel (HSS) with a V-coat finish, this tap delivers clean thread formation in carbon steel, stainless steel, aluminum, and hardened steel. The 3-flute geometry provides good chip clearance in through and blind hole applications. With an overall length of 3.94 inches and a thread length of 0.748 inches, the 1658502008 is sized for standard pipe tap holders and wrenches used by machinists, pipefitters, and plumbing fabricators working to BSP standards.\u003c\/p\u003e\u003cp\u003eThis tap is intended for applications requiring BSPT tapered threads, commonly found in fluid and gas line fittings, hydraulic components, and pipe assemblies governed by British Standard specifications. The right-hand thread direction suits standard tapping operations on benchtop machines or hand-driven tap wrenches. It is a practical choice for shops and field fabricators cutting pipe threads in metric-adjacent systems, particularly in industrial, marine, and import-equipment repair contexts where BSP thread forms are specified.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThread size: 1\/4-19 BSPT tapered pipe thread form\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction rated for carbon steel, stainless steel, aluminum, and hardened steel\u003c\/li\u003e\n\u003cli\u003e3-flute design for efficient chip evacuation during tapping\u003c\/li\u003e\n\u003cli\u003eV-coat finish reduces friction and extends tool life\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction for use with standard tap wrenches and tapping heads\u003c\/li\u003e\n\u003cli\u003eNo coolant-through requirement — suitable for hand and machine tapping with conventional cutting fluid\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard tap holders and wrenches accepting a 0.56-inch shank diameter with a 0.42-inch square drive.

Secure the workpiece fully before tapping, and apply an appropriate cutting fluid for the material being threaded. Start the tap squarely to avoid cross-threading, and back off periodically to break chips. Never force a tap that meets resistance — back out to clear chips before continuing.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-19 BSPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: BSPT\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\u003eOverall Length\u003c\/strong\u003e: 3.94 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.748 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.56 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.42 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.437 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: V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Carbon Steel, Stainless Steel, Aluminum, Hardened Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 16585\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.22 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: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1658502008\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51728853991730,"sku":"1658502008","price":144.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1d9a1ae4cdbb7a8425d32bb3ea6a66de.jpg?v=1788696891","url":"https:\/\/voomisupply.com\/products\/osg-1658502008-bspt-pipe-tap-1-4-19-3-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
