Built from vanadium high speed steel (HSS-E) with a steam oxide coating, this tap delivers improved lubricity and corrosion resistance during through-hole tapping operations. The spiral point geometry pushes chips ahead of the tap and out of the hole, reducing chip packing and allowing consistent cutting at production feed rates. With an H5 thread limit, it holds close tolerances suitable for precision fastener applications. Licensed HVAC techs, machinists, and maintenance professionals working on sheet metal enclosures, electrical panels, and mechanical assemblies routinely use this style of tap.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for through-hole tapping in residential and commercial maintenance environments as well as light manufacturing. The 8-32 UNC thread form is one of the most common machine screw threads encountered in electrical enclosures, HVAC equipment panels, control boxes, and plumbing fixture hardware. Compatible material applications include aluminum, low-carbon steel, medium-carbon steel, high-carbon steel, alloy steel, die steel, stainless steel, hardened steel, and cast iron, making it a versatile choice when a single tap needs to handle mixed-material work orders.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSpiral point geometry pushes chips forward through the hole, preventing chip packing in through-hole applications\u003c\/li\u003e\n  \u003cli\u003eVanadium high speed steel (HSS-E) construction provides increased toughness and wear resistance compared to standard M2 HSS\u003c\/li\u003e\n  \u003cli\u003eSteam oxide coating improves lubricity and reduces built-up edge on the cutting face\u003c\/li\u003e\n  \u003cli\u003eH5 thread limit holds close tolerances for precision fastener fits\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer (3-5 thread lead) balances starting ease with thread engagement depth\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, 3-flute design compatible with standard CW-rotating tap handles and machine tapping heads\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 8-32 UNC spiral point plug tap for use in through-hole tapping operations across aluminum, carbon steels, alloy steels, stainless steel, die steel, hardened steel, and cast iron workpieces.

Always use a suitable cutting fluid matched to the workpiece material to extend tool life and improve thread quality. Ensure the tap is started square to the drilled hole to prevent tap breakage and thread misalignment. Secure the workpiece firmly before tapping; never attempt to back out a broken tap without proper extraction tooling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 8-32\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Vanadium High Speed Steel (HSS-E)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Steam Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.126 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.374 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.168 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInterrupted Thread\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOversize\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 280\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.016 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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 2817801\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51727741747506,"sku":"2817801","price":31.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/74a700afb1ebe688f72ab0771c8dcbc1.jpg?v=1788681515","url":"https:\/\/voomisupply.com\/products\/osg-2817801-spiral-point-tap-8-32-unc-3-flute-plug","provider":"Voomi Supply","version":"1.0","type":"link"}
