How to Choose the Optimal Knock Pin

Our positioning pins are used in a wide range of industries, including aerospace, medical, motion control, manufacturing, and defense.
Here, we will explain the main factors to consider when selecting positioning pins.
Pin Size
The size of the pin is determined by two important metrics: outer diameter (O.D.) and length.
Outer Diameter (O.D.): Ranges from 0.04 to 0.47 inches (1 to 12 mm)
Length: Ranges from 0.24 to 3.14 inches (6 to 80 mm)
*Customizable based on drawings
Fit and Tolerance
The outer diameter should be determined by the fit required for the application:
Press Fit: This positioning pin is slightly oversized and is suitable for precision assemblies that require accurate alignment.
Sliding Fit: Easily installed and removed without tools, making it ideal for self-locating assemblies.
