01 / LOOK UP
Find a specification
Start with a marking or measurements.
Choose a reference ↓ 02 / COMPARECompare dimensions
See what changes between nearby sizes.
Choose a comparison ↓ 03 / CALCULATECalculate a parameter
Use known inputs, with units and assumptions.

Threads & tapping
Find the specification before choosing the tapping drill.
Look up a thread size →Identify an unknown thread →Find a tapping drill →Materials
Look up a grade, then confirm its material condition and source.
Find a material grade →Compare grades and states →Read a material callout →Tolerances & finishes
Read drawing requirements, compare size limits and calculate with known conditions.
Explore tolerances & finishes →What does Ra 1.6 µm mean? →Convert µm and µin →Compare the specifications and conditions

Check the source, keep the conditions
Nominal dimensions, manufacturer data and calculated results have different scopes. Each reference keeps those boundaries visible.
