It cuts internal threads in a 5\/16-inch diameter hole with 18 threads per inch (UNC coarse thread pitch). The plug chamfer style — typically 3 to 5 threads of lead — makes it suitable for through-holes and most blind-hole applications where a starting tap has already been used or where a single tap is run through the full threading operation. Machinists, pipefitters, and maintenance technicians install this tap by hand with a standard tap wrench.\u003c\/p\u003e\n\u003cp\u003eThis tap is used in general metalworking, maintenance and repair, and light manufacturing settings. It is appropriate for threading mild steel, aluminum, brass, and similar machinable materials in both shop and field environments. The 5\/16-18 UNC thread form is one of the most common fastener sizes in North American mechanical assemblies, making this tap a standard item in trade tool kits and shop tap-and-die sets.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC thread form — coarse pitch, standard North American fastener size\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer style suits both through-hole and blind-hole threading\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel (HSS) construction for durability across ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eUSA manufactured\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.06 pounds — easy to handle in confined or overhead work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a hand tap for use with standard tap wrenches accepting the appropriate square shank drive.

Ensure the workpiece is securely clamped before threading. Apply appropriate cutting fluid to the tap to reduce friction and extend tool life. Back off the tap periodically to break chips and prevent binding, especially in blind holes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTap Style\u003c\/strong\u003e: Hand Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel (HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: USA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: EAGLE CUTTING TOOL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: HT-3125-18-P-D\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51233710866738,"sku":"HT-3125-18-P-D","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307622818.png?v=1780107390","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-ht-3125-18-p-d-5-16-18-hss-hand-plug-tap","provider":"Voomi Supply","version":"1.0","type":"link"}
