Keenserts® High-Strength Inserts
Keenserts® high-strength threaded inserts are designed to provide permanent, wear-resistant threads in softer materials like aluminum, magnesium, and composites.
Manufactured by Howmet Fastening Systems, Keenserts® feature solid steel construction with internal and external threads, plus locking keys that mechanically secure the insert against rotation and pull-out. They are ideal for demanding applications in aerospace, defense, automotive, and industrial equipment, especially where high load strength and thread integrity are critical. Easy to install and remove, Keenserts are a go-to solution for restoring damaged threads or reinforcing new assemblies.
