The plug chamfer — typically 3 to 5 threads of lead — makes this tap the standard starting choice when threading through-holes or when sufficient clearance exists below the hole. At 0.31 pounds, it is lightweight enough for single-hand use with a standard tap wrench. Machinists, pipefitters, millwrights, and general fabricators rely on HSS plug taps for reliable thread-cutting performance across a wide range of ferrous and non-ferrous materials.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for threading 5\/16-18 Unified National Coarse (UNC) threads by hand in shop, field, and maintenance environments. Typical applications include threading bolt-hole repairs, creating new tapped holes in fixtures, and restoring damaged threads in structural or mechanical components. It is commonly used in light industrial, HVAC equipment assembly, plumbing bracket fabrication, and general mechanical maintenance work where a standard coarse-thread 5\/16 inch tap is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC thread form for standard coarse-thread applications\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel (HSS) construction provides hardness and wear resistance across a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer style offers a balance of easy thread starting and versatility in through-hole and open-bottom applications\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.31 pounds for comfortable hand-tap wrench use\u003c\/li\u003e\n  \u003cli\u003eMinimum order quantity of 1 — available as a single unit for toolbox stocking or job-site use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard hand plug tap for use with conventional tap wrenches or T-handle tap holders sized for 5\/16-18 UNC threading work in metalworking and maintenance applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap is intended for hand-tapping only — do not use in power-driven tap holders unless the tool is explicitly rated for machine use. Secure the workpiece firmly before threading and apply appropriate cutting fluid to extend tap life and improve thread quality. Start the tap perpendicular to the workpiece surface to avoid cross-threading or tap breakage. Broken taps are difficult to remove; use steady, controlled pressure and back off periodically to clear chips.\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 Type\u003c\/strong\u003e: Hand Plug Tap\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel (HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.31 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 1\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-I\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51233918583090,"sku":"HT-3125-18-P-I","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307622812.png?v=1780112147","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-ht-3125-18-p-i-5-16-18-hss-plug-tap","provider":"Voomi Supply","version":"1.0","type":"link"}
