Manufactured from high-speed steel (HSS) with a gold oxide coating, it delivers solid wear resistance and reduced friction during threading operations. The plug chamfer style provides a gradual thread lead-in, making it well suited for through-holes and moderately deep blind holes. With 4 flutes and an H3 thread limit, this tap produces threads to standard tolerance requirements expected in production and maintenance threading work. Overall length is 2-23\/32 inches.\u003c\/p\u003e\u003cp\u003eThis tap is used in machine shop, maintenance, repair, and manufacturing environments where UNF fine-thread tapping is required. It handles through-hole and blind-hole applications in ferrous and non-ferrous metals, plastics, and similar machinable materials. The 5\/16-24 UNF thread form is common in automotive, aerospace, and general mechanical assembly work where fine thread engagement is specified.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5\/16-24 UNF thread form for fine-pitch internal threading\u003c\/li\u003e\n\u003cli\u003e4 straight flutes for chip clearance in through-hole and blind-hole use\u003c\/li\u003e\n\u003cli\u003ePlug chamfer for gradual thread lead-in and versatile hole types\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction for durability across common machinable materials\u003c\/li\u003e\n\u003cli\u003eGold oxide coating reduces friction and improves lubrication retention\u003c\/li\u003e\n\u003cli\u003eH3 thread limit for consistent tolerance compliance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard replacement or production tap for any application requiring a 5\/16-24 UNF straight flute plug tap with an H3 thread limit.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap is installed by licensed machinists or maintenance technicians using a tap wrench, tapping head, or CNC machine spindle.
