What Is an Alignment Pin?
An alignment pin is a tool used for the precise positioning of workpieces, jigs, and other components during machining or assembly processes.
Alignment pins come in a wide variety of specifications but can generally be categorized into two main types: parallel pins and taper pins. Parallel pins are cylindrical and facilitate the alignment of two pieces during assembly, ensuring their correct positional relationship by being inserted into the assembled parts.
Similar in shape to parallel pins, taper pins are cylindrical but taper towards one end. They are primarily used for accurately positioning and securing shafts into bosses, offering a secure fit.
