Frequently Asked Questions

Q: What materials can these HSS metric hand taps cut threads into?

A: These high speed steel hand taps are suitable for threading iron, mild steel, stainless steel, copper, aluminum, and die steel. The HRC 62 hardness rating ensures reliable performance even in tougher alloys like stainless steel.

Q: What pitch do these taps use, and are they suitable for fine-thread applications?

A: Yes — all sizes in this set feature a 1.5mm pitch, which is a fine metric thread specification. This makes them ideal for applications requiring tighter thread engagement and greater holding strength, such as precision machinery, automotive components, and structural assemblies.

Q: How do I choose the right size from M12, M14, M16, M18, and M20?

A: Select the tap size that matches the nominal diameter of the bolt or fastener you need to thread. For example, choose M16 × 1.5mm if you need to create a hole that accepts a 16mm fine-pitch bolt. Always drill the correct tap drill size before threading — for 1.5mm pitch, the recommended drill sizes are: M12 → 10.5mm, M14 → 12.5mm, M16 → 14.5mm, M18 → 16.5mm, M20 → 18.5mm.

Q: Why do I get 2 taps in each set?

A: Each pack includes 2 identical taps so you have a reliable backup on hand for production runs, or can keep one as a spare in case of breakage during heavy-duty threading operations. It's a great value for both professional workshops and home garages.
