- Scope
- This part specifies the round head grooved pins whose nominal diameter d1 is 1.4mm~20mm, made of cold heading steel, and have three longitudinal grooves of 120° on the pin surface. The expanded diameter d2 is formed by the extruded material on each side of the groove, and d2 is greater than d1. When the grooved pin is pressed into a borehole with a diameter equal to the nominal diameter d1, a partial locking fit is formed (see Chapter 4).
