Klik® Poly-Nuts

Available in Steel-Zinc Plated or Aluminum Class 2B Threads

Klik Poly-Nuts can be used in a wide range of applications and are designed to provide a very efficient and cost-effective method of placing permanent threads in thin materials. Installed from one side, Klik Poly-Nuts are perfect for use in metal, fiberglass and rigid plastic previously too thin for tapped threads. Klik Poly-Nuts provide a nearly flush appearance and once in place, the internal threads are ready for a screw or bolt.  Lightweight tooling assures easy installation by the operator and reduces costs when compared with other methods. After installation, Klik Poly-Nuts provide permanent, captive threads that do not allow loosening under vibration and will not rotate when attached to the mating material.
