BAERfix Self Tapping Inserts

BaerFix are self tapping inserts from BAER, Germany, that are designed to cut their own threads as they are being driven into a drilled hole (self tapping). This provides a secure and high strength anchor in the parent material.

BaerFix inserts do not require special tools for tapping.



BaerFix is typically used for thread repair and thread reinforcement.
