It features a plug chamfer for gradual thread engagement and a steam oxide coating that improves lubricity and reduces chip welding during the tapping process. The tap is manufactured from high-speed steel, providing the hardness and wear resistance needed for repetitive production tapping. With 3 flutes and a spiral point geometry, it pushes chips ahead of the cut rather than packing them into the flute, making it well suited to through-hole work in softer metals and steel.\u003c\/p\u003e\n\u003cp\u003eThe OSG 2885901 is rated for use in aluminum, cast aluminum, low-carbon steel, and medium-carbon steel. It is commonly used in machine shop, maintenance, and light manufacturing environments where 5\/16-24 UNF threaded holes are required in through-hole configurations. The plug chamfer makes it appropriate for both hand tapping and machine tapping setups where the tap enters a clear through-hole.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-24 UNF thread form with 2B class of fit for standard commercial thread tolerance\u003c\/li\u003e\n  \u003cli\u003eSpiral point geometry pushes chips forward, reducing clogging in through-hole applications\u003c\/li\u003e\n  \u003cli\u003e3-flute plug chamfer design for gradual thread engagement and balanced cutting forces\u003c\/li\u003e\n  \u003cli\u003eSteam oxide coating improves lubricity and extends tool life in steel and aluminum\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides hardness and toughness for production tapping cycles\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction; no coolant-through feature required for typical applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for use in aluminum, cast aluminum, low-carbon steel, and medium-carbon steel.

Cutting fluid or tapping compound should be applied to extend tool life and improve thread quality. Ensure the workpiece is securely fixtured and the hole is drilled to the correct tap drill diameter for a 2B class of fit before tapping. Do not reverse the tap under load without first relieving chip pressure to avoid tap breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-24 UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: 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: High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Steam Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.719 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.717 inches (1-1\/8 inches nominal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.318 inches\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\u003eInterrupted Thread\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Aluminum, Cast Aluminum, Low-Carbon Steel, Medium-Carbon Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 287\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.053 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: 2885901\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51731955712306,"sku":"2885901","price":20.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2527bc397814a54fa7a40805d57c7ab5.jpg?v=1788737204","url":"https:\/\/voomisupply.com\/products\/osg-2885901-spiral-point-tap-5-16-24-unf-3-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
