Complete metric hand tap set covering sizes from M3 to M27 in a protective storage box. Each size includes 3 taps per set (taper, plug, and bottoming) for full-depth thread cutting in through-holes and blind holes. Made from alloy steel (9CrSi/Cr-V) with black oxide finish for corrosion resistance.
Designed for manual threading in repair shops, maintenance departments, and light fabrication. The straight flute design handles carbon steel, alloy steel, aluminum, and cast iron. The square drive shank fits all standard tap wrenches and T-handle tap holders.
Custom set configurations available — we can adjust the size range, mix coarse/fine threads, or add custom packaging with your brand. MOQ: 20 sets per order. All taps are manufactured and inspected in our Hangzhou factory under ISO 9001 quality control.
