Free Running Tanged Inserts – RECOIL® Insert Installation Tools
RECOIL™ helically wound wire thread inserts can be used to strengthen threads, giving applications a longer life.
Each insert sharing the load over the entire bolt and hole, improving holding or pull out resistance. With a Recoil insert installed, a more even distribution of load and stress can be achieved. Recoil inserts are generally made of type 304(18-8) stainless steel wire rolled into a diamond shape cross-section.
