Where this product is used

Metric taps cut internal threads to ISO standards — thread type (coarse or fine), style (taper, plug, bottoming), and material grade are the key variables.

• Threading metric holes in steel, stainless steel, and aluminium in engineering and fabrication
• Machine shops, maintenance, and repair operations requiring metric internal threads
• Automotive, agricultural, and general engineering thread repair and creation

Key specifications

Selecting the right option

Tap style is matched to the application: a taper tap starts the thread easily; an intermediate (plug) tap continues it; a bottoming tap threads to the bottom of blind holes. HSS suits general steel and aluminium; HSS-Co is required for stainless and hard alloys. The pitch must match the thread specification — metric coarse is the default; metric fine is used where vibration resistance or greater thread engagement per unit length is needed.
