Built from high speed steel with a bright, uncoated finish, this tap delivers consistent thread quality in general-purpose tapping applications. The plug chamfer (3-5 threads) makes it suitable for through-holes and moderately deep blind holes. With a 4-flute design and an H2 thread limit, it produces threads to tight tolerances with reliable chip clearance. Overall length is 2-23\/32 inches with a 1-1\/8-inch thread length, a 0.318-inch shank diameter, and a 0.238-inch square drive size.\u003c\/p\u003e\u003cp\u003eThis tap is used in machine shops, maintenance and repair operations, and production environments where 5\/16-24 UNF threaded holes are required. It is a manual hand tap intended for use with a tap wrench or holder. Typical applications include threading steel, aluminum, brass, and similar machinable materials. The straight-flute geometry works well in through-hole and short blind-hole applications where chips can be backed out during the tapping cycle.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5\/16-24 UNF right-hand thread form for standard unified fine-pitch applications\u003c\/li\u003e\n\u003cli\u003ePlug chamfer with 3-5 thread lead for starting ease in through-holes and moderate blind holes\u003c\/li\u003e\n\u003cli\u003e4-flute straight-flute design provides chip clearance and stable cutting action\u003c\/li\u003e\n\u003cli\u003eH2 thread limit for close-tolerance thread production\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction for durability across common machinable materials\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for use with cutting oil or tapping fluid\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard hand tap for use with any tap wrench or holder accepting a 0.318-inch round shank with a 0.238-inch square drive, and sized for 5\/16-24 UNF threaded hole applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap is intended for use by machinists and maintenance technicians using a tap wrench or adjustable tap holder. Secure the workpiece before tapping and ensure the correct pilot hole diameter is drilled per UNF tap drill charts prior to use. Apply an appropriate cutting oil or tapping fluid to reduce friction and extend tool life. Back the tap out periodically to break and clear chips, especially in deeper holes.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-24\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-23\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1-1\/8 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\u003eSquare Size\u003c\/strong\u003e: 0.238 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: 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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: K008407AS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51737405063474,"sku":"K008407AS","price":19.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7bfc7d5547809044b737792b2ee3cc82.jpg?v=1793374753","url":"https:\/\/voomisupply.com\/products\/hertel-k008407as-hand-tap-5-16-24-unf-plug-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
