HC Series: Headed Chevron Threaded Inserts for Weaker Plastics
Our HC Series headed chevron threaded inserts offer the same benefits as the C Series, plus a flanged head for a greater load-bearing surface in weaker plastics. This headed insert offers a large contact area for electrical connections and greater pull-out strengths for reverse entry applications.
