The Wiseman Threading Tools Hand Tap with +0.015 tolerance is a precision hand-tool designed to cut clean, accurate internal threads in metal components. Built for reliability, it yields repeatable results across multiple taps and projects, helping you move from rough holes to fully formed threads with confidence.

Bottoming geometry (bottom lead) ensures you can thread all the way to the bottom of blind holes, delivering full-depth engagement where it matters most. This makes it a trusted choice for repairs and fabrication tasks where thread depth cannot be compromised.

Size and tolerance at a glance: M16x2 with +0.015 tolerance. This tight tolerance supports consistent thread pitch and outer diameter, reducing the risk of loose fits or cross-threading when paired with standard M16x2 components.

Construction and longevity: crafted from durable tool steel and finished to withstand repeated hand tapping. The edge retention and rigidity help resist wear, so you can rely on this Wiseman hand tap for longer, even in busy workshops or on demanding projects.

Ideal use cases include:

• Repair or re-tap stripped internal threads in housings, brackets, or enclosures where precise engagement is critical.
• Fabrication projects that require accurate, full-depth M16x2 threads in blind or through holes.
• Automotive work, machinery maintenance, and industrial equipment where dependable hand tapping saves time and ensures a proper fit.

Tips for best results:

• Secure the tap in a T-handle or drill press with a chuck for stable alignment.
• Use a quality cutting fluid or tapping oil to minimize heat and chip buildup.
• Turn steadily in the correct direction, and back off occasionally to break chips and maintain thread quality.
• Test-fit with the corresponding fastener during and after tapping to confirm depth and engagement.

With the Wiseman Threading Tools Hand Tap, you’re equipping your workshop with a precise, dependable tool designed to deliver clean threads and repeatable performance—time after time.
