The design of a spring bolt

The FEBI BILSTEIN brand Spring Bolt are ground until the most accurate fit size is reached. Compared to standard screws, these structural elements are distinguished by the absence of metric threads. Their profile angle is 90⁰. This parameter matches the corresponding spring bushing. To securely fix products, manufacturers provide a special groove on the head. In addition, fixing is possible with a cotter bolt directly in the castle nut.
