Introducing the Wiseman Threading Tools Hand Tap, a precision instrument engineered to create robust internal threads by hand with unmatched consistency. Designed as a second-lead tap, it combines speed with control for reliable hole threading, and its +0.015 tolerance ensures consistent thread dimensions and dependable mating with mating components. Sized for M16x2 internal threads, this tap is a versatile choice for a wide range of metalworking projects where thread quality matters as much as reliability.

• Double-lead (second lead) design accelerates threading without sacrificing accuracy, making manual tapping more efficient for larger diameter holes.
• +0.015 tolerance delivers precise thread dimensions and tight fits, so assemblies thread smoothly every time.
• Durable construction stands up to demanding hand tapping, maintaining sharp cutting edges for repeated use.
• Metric M16x2 specification targets a common, widely used internal thread size, suitable for a broad array of components and accessories.
• Ideal for hand threading applications—from repairs and retrofits to new fabrications—where precise internal threads are critical and machine taps aren’t practical.

In practice, this Wiseman hand tap helps you achieve clean, accurate threads with minimal rework. Use with a compatible tapping handle or wrench, apply a light cutting lubricant, and turn steadily to maintain alignment. Back off periodically to clear chips, then finish with a quick inspection to ensure the threads meet your exacting standards. For anyone tackling precision metalwork where the integrity of internal threads matters, this second-lead hand tap from Wiseman is a dependable, long-lasting choice that delivers consistent results project after project.
