Tie Wire Anchors are female concrete anchors designed for anchoring into concrete. Drop the anchor into the pre-drilled hole in the concrete. Using a setting tool expands the anchor within the hole in the concrete.In order to make the fixation more firm, the surface of the internal forcing casing is usually set with uneven patterns, but the inner wall of the drilling hole is often very rough, and the effect of ordinary pattern is very limited, and it can not play a good role in further reinforcement.
