Plug taps are the standard starting tap for most threading jobs, with a chamfer on the first 3-5 threads that eases entry into a pre-drilled hole and distributes cutting load across multiple threads. This tap is sized for the 1\/4-28 UNF (Unified Fine Thread) standard, a fine-pitch thread common in precision mechanical assemblies, instrumentation, and fluid fittings. It is designed for hand tapping operations using a tap wrench or T-handle and is suited for use in steel, cast iron, aluminum, brass, and similar materials.\u003c\/p\u003e\n\u003cp\u003eThe 1\/4-28 thread size sees wide use in HVAC, plumbing, electrical, and general mechanical trade work, particularly where fine-thread engagement is needed for secure fastening in thin-walled or vibration-prone assemblies. Typical applications include threading blind or through holes in brackets, fittings, valve bodies, and control enclosures. This tap is used by machinists, maintenance technicians, pipefitters, and field service professionals who need a reliable hand tap for production or repair threading work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-28 UNF fine-thread profile for precise thread engagement\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer (approximately 3-5 threads) suits the majority of through-hole and open blind-hole tapping applications\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides hardness and wear resistance across a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eUSA manufactured to standard tap geometry and tolerances\u003c\/li\u003e\n  \u003cli\u003eMinimum order quantity of 1 — suitable for single-unit purchase\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard hand plug tap for any application requiring 1\/4-28 UNF internal threads.

Secure the workpiece firmly and align the tap square to the hole before applying torque. Apply cutting fluid appropriate to the workpiece material throughout the tapping operation. Back the tap off periodically to break chips and prevent tap binding or breakage in deeper holes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-28 UNF\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\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-2500-28-P-D\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51233609220402,"sku":"HT-2500-28-P-D","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307622847.png?v=1780104546","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-ht-2500-28-p-d-1-4-28-hss-hand-plug-tap","provider":"Voomi Supply","version":"1.0","type":"link"}
