Headed Chevron Threaded Inserts for Weaker Plastics

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.

Recommended Hole Size – See chart below for installation hole size. Additional information can be found in our Design Guidelines.
