5/8"-18 UNF Tap and Die Set, Right-Hand HSS M2 Machine Thread Tap Die Set

Key features

• 5/8"-18 UNF Right-Hand Thread – Standard fine thread pitch for machine threading; ensures a tight fit on 5/8" UNF fasteners
• High Speed Steel 6542 (HSS) – Withstands high torque and heat; retains cutting edge when threading stainless steel and tool steel
• Tap and Round Die Set – Includes a machine thread tap for internal threads and a round die for external threads
• For Stainless Steel & Hard Alloys – Engineered to resist chip welding and provide clean threads in corrosion-resistant materials
• Versatile Threading Tool Kit – Use for automotive cylinder heads, hydraulic fittings, and general repair work
• Ultrasonically welded outer shell creates a permanent seal; any opening attempt leaves irreversible traces, ensuring brand-new products. The inner storage case prevents metal-on-metal friction during transit, protecting cutting edges and coating, and serves as permanent organizer by size. This dual design combines tamper-evident security with a reusable case that lasts the drill bits' entire life

Designed for heavy-duty threading operations, this 5/8"-18 UNF tap and die set features High Speed Steel 6542 for long service life when cutting stainless steel, carbon steel, and alloy steels. The right-hand machine thread configuration is ideal for both lathe work and manual threading. Each set includes a taper tap for gradual cutting and a fully adjustable round die for external threading. The 5/8x18 UNF pitch provides finer threads than coarse series, increasing tensile strength and preventing loosening under vibration. Perfect for automotive repair, hydraulic fittings, and structural steel fabrication
