It features a 5\/16-24 UNF thread form, three flutes, and a plug chamfer that provides a gradual lead-in for controlled thread engagement. Manufactured from HSS-E Vanadium high speed steel with an oxide finish, this tap offers improved hardness and wear resistance compared to standard HSS tooling. With an H5 thread limit, it is suited for applications requiring a close-tolerance fit. Typical users include machinists, maintenance technicians, and industrial tradespeople working with ferrous and non-ferrous materials.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for through-hole tapping operations in production and maintenance environments. The spiral point design pushes chips forward ahead of the tap, making it effective in CNC and hand-tapping setups where chip clearance is a priority. The plug chamfer — typically 3 to 5 threads — allows the tap to start easily in pre-drilled holes. Coolant-through capability is not included, so external cutting fluid or tap lubricant is recommended when machining steel or stainless materials to extend tool life and maintain thread quality.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-24 UNF thread size for fine-pitch through-hole tapping\u003c\/li\u003e\n  \u003cli\u003eHSS-E Vanadium construction for enhanced hardness and wear resistance over standard HSS\u003c\/li\u003e\n  \u003cli\u003eOxide finish reduces friction and provides mild corrosion resistance during storage\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer provides gradual thread engagement, suitable for most general through-hole applications\u003c\/li\u003e\n  \u003cli\u003eH5 thread limit ensures close-tolerance thread fit\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction; three-flute design promotes efficient chip evacuation in through-holes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement spiral point tap for through-hole tapping operations requiring a 5\/16-24 UNF thread form in manual or CNC machining applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap is installed by machinists or maintenance technicians using a tap wrench, tapping head, or CNC rigid tapping cycle. Always ensure the pilot hole is drilled to the correct tap drill diameter for a 5\/16-24 thread before starting. Apply cutting fluid or tapping compound to extend tool life and improve thread finish, particularly in steel and stainless steel. Power down or de-energize any machine fully before changing tooling in a manual setup.\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\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: HSS-E Vanadium High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.7205 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.866 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.318 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 1.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: T1640465\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51730712625458,"sku":"T1640465","price":29.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5fef260b85cc65782c9d881e9a6c5ca2.jpg?v=1788721662","url":"https:\/\/voomisupply.com\/products\/accupro-t1640465-spiral-point-tap-5-16-24-3-flute-plug","provider":"Voomi Supply","version":"1.0","type":"link"}
