Method for anchoring a mounting element in a mineral component

摘要

The method involves screwing a fastening element (11) into a bore hole (2), where the element comprises a cylindrical shaft (12) provided with a rotary engagement unit (16) for a setting tool. The shaft is provided with a core diameter and a cutting edge (21) on an end region. The element is provided with a self-tapping thread (17) in which a difference between an outer diameter of the thread and the core diameter corresponds to 0.05 to 0.7 times a pitch of the thread. The bore hole is used with a bore hole diameter, which corresponds to 0.95 to 1.10 times the core diameter of the shaft. An independent claim is also included for a fastening element for a mineral component comprising a shaft.
