Metric Tap Diameter and Pitch Guide

Metric threading uses nominal diameter plus pitch, so both values must be matched before selecting a tap or set.

Taps for professional work

Cutting Tools Outlet organizes this selection by tool type, size, material and application so machinists, fabricators, maintenance teams, contractors and purchasing departments can reach the right configuration faster.

  • Read the specification as diameter by pitch, such as M8 x 1.25.
  • Use the correct metric tap drill for the selected pitch.
  • Keep coarse and fine pitch tools clearly separated in the shop.
