TIGHTNIK is a washer that prevents loosening due to vibration and aging. ■ It will be tightened following clearance generated by thinned wood. The built-in magic rings will be pressed by the springs, pulling the bolts, and the magic rings keep the bolts tight. ■ Tightened by vibration The magic ring converts vibrations caused by earthquakes, wind during typhoons and motor vehicles to the tightening force, so the structure will not be loosened and the house stays shake-resistant. ■ Gentle to the wood and humans Light clamping yet resistant to a great force. ■ It is effective on soft objects such as wood, rubber, resin and aluminium.
