Dowel pins DIN 7979 connect, secure and position machine parts.
They are used in conjunction with blind holes. The centering step facilitates with pressing in the part. The flat section relieves trapped air, making them easier to insert and remove.
The dowel pin can be removed via the internal thread using a puller handle or slide hammer. The protective countersink d3 on the thread protects it from damage during installation.
The dimensions correspond to ISO 8735. In combination with a location hole H7 a transition fit can be achieved.
