It features a 3\/8-24 UNF thread form, three flutes, and a plug chamfer for standard through-hole tapping applications. The tap is manufactured from 3% vanadium high speed steel, which provides improved wear resistance and toughness over standard M2 HSS. A bright finish is applied, leaving the base steel surface uncoated. Overall length is 2.9400 inches and thread length is approximately 0.945 inches (24.00 mm). The 2B class of fit meets standard tolerance requirements for general-purpose threaded assemblies.\u003c\/p\u003e\u003cp\u003eThis tap is suited for production and maintenance tapping of through holes in steel workpieces where a 3\/8-24 UNF thread is required. The spiral point geometry pushes chips forward ahead of the tap, making it most effective in through-hole applications rather than blind holes. It is commonly used by machinists, toolmakers, and maintenance technicians working on threaded fastener repairs, fixture fabrication, and general metalworking tasks. The plug chamfer provides a moderate lead-in that balances starting ease with thread engagement length.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/8-24 UNF thread size for fine-pitch through-hole tapping\u003c\/li\u003e\n\u003cli\u003e3% vanadium high speed steel construction for enhanced wear resistance over standard HSS\u003c\/li\u003e\n\u003cli\u003eThree-flute spiral point design pushes chips forward in through-hole applications\u003c\/li\u003e\n\u003cli\u003ePlug chamfer provides moderate lead-in and thread engagement\u003c\/li\u003e\n\u003cli\u003e2B class of fit meets standard general-purpose tolerance requirements\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction for conventional tapping operations\u003c\/li\u003e\n\u003cli\u003eBright finish with no coating for straightforward application in steel\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard tooling selection for machines and tapping heads accepting straight-shank taps with a 9.68 mm shank diameter in 3\/8-24 UNF applications.

Ensure the workpiece is securely fixtured and that the correct tap drill size for a 3\/8-24 UNF thread has been used prior to tapping. Apply cutting fluid appropriate for steel to extend tap life and improve thread quality. Do not reverse the tap under power without confirming the machine setup supports reversing cycles, and never force a tap that has stopped advancing.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-24 UNF\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\u003eClass of Fit\u003c\/strong\u003e: 2B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: 3% Vanadium 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\u003eOverall Length\u003c\/strong\u003e: 2.9400 inches (74.61 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.945 inches (24.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.381 inches (9.68 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\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\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: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: T2640502B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51732941799730,"sku":"T2640502B","price":52.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8df3e47b0add032c981ee9f00ebe0254_6d8458a0-1cf4-44f1-9465-c08478dcea90.jpg?v=1788749249","url":"https:\/\/voomisupply.com\/products\/accupro-t2640502b-spiral-point-tap-3-8-24-3-flutes-plug","provider":"Voomi Supply","version":"1.0","type":"link"}
