• Is full profile or partial profile required?
• What is the threading profile (square,
triangular, trapezoidal or other)?
Pitch or TPI
• What is the threading standard?

• What is the threading pitch / TPI?
Required full profile according to ISO standard M20x1.75, meaning a triangular thread form
with an angle of 60°.
