Alcoa Fastening Systems' Recoil brand of tangless inserts are designed to reduce production costs by eliminating the time required to remove the tang and retrieve it. The inserts also provide additional security by removing the possibility of foreign objects (the tang) being left behind in the final product. Bidirectional design eliminates an insert orientation requirement. The devices provide easy installation of a female thread with the necessary holding power for a range of applications. They are approved for use on military programs by NASM8846 and NAS1130.
