These cap screws are cost-saving construction elements for a wide variety of different uses, and can be used to simplify complicated designs. They are made to the DIN 912 standard.
The requirements of this 3211 standard DIN 912 state the recommended minimum thread length of this product is 2x the thread diameter plus 12mm. Available in Class 12.9 only. Many customers have situations that require a much longer thread length where we would recommend our 528 shoulder bolt.
