Built from HSS-E cobalt steel with a steam oxide finish, it produces clean 4-40 UNC internal threads in a single pass through a drilled hole. The plug chamfer style eases entry and distributes cutting forces gradually across the leading threads. At 1.882 inches overall length with a 0.433-inch thread length, this tap fits standard tapping chucks and hand tap holders used in production and maintenance environments. Licensed machinists, tool-and-die makers, and maintenance technicians rely on this style of tap for precision thread generation in light fastener applications.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for threading 4-40 UNC through-holes in steel workpieces in both production shop and field maintenance settings. The spiral point geometry pushes chips forward ahead of the cutting flutes, making it well-suited for through-hole applications where chip evacuation into the bore is acceptable. The H2 thread limit and 2B class of fit target standard fastener assemblies requiring moderate thread tolerances. Series 4402 taps from GUHRING are a recognized format in CNC tapping, turret lathe, and hand-tapping operations where consistent thread form and tool life in steel are priorities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-40 UNC thread form, right-hand cut, 40 threads per inch\u003c\/li\u003e\n  \u003cli\u003eHSS-E cobalt construction for improved heat and wear resistance in steel\u003c\/li\u003e\n  \u003cli\u003eSteam oxide finish reduces friction and improves chip flow\u003c\/li\u003e\n  \u003cli\u003eSpiral point design pushes chips forward for clean through-hole threading\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer distributes entry load across multiple leading threads\u003c\/li\u003e\n  \u003cli\u003eH2 thread limit, 2B class of fit for standard fastener tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for through-hole threading of steel workpieces requiring 4-40 UNC internal threads.

Always ensure the workpiece is securely fixtured and the tap is properly aligned with the drilled pilot hole before beginning the threading cycle. Use a cutting fluid or tapping compound appropriate for the workpiece material to reduce heat and extend tool life. Follow applicable shop safety procedures and machine guarding requirements when operating tapping equipment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 4-40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Pitch\u003c\/strong\u003e: 0.025 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.433 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.276 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.882 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.141 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStyle\u003c\/strong\u003e: Spiral Point\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: HSS-E Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Steam Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Through-Hole Threading\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: 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: 4402\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: GUHRING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9044023028450\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51738112590130,"sku":"9044023028450","price":25.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b62df8318d3f20b3552ac1fcbda1d76f_1ea3aae7-94dc-4975-9f98-189caff6badb.jpg?v=1788796274","url":"https:\/\/voomisupply.com\/products\/guhring-9044023028450-spiral-point-tap-4-40-unc-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
