Seismic seat tightener that does not degrade the seismic performance at the time of new construction.

As a joining hardware for wooden houses, it protects the house from earthquakes and typhoons and prevents a decline in seismic performance.

"As the only connecting hardware for wooden houses, it has passed the vibration test of the U.S. aerospace standard NAS3350." Main Features It prevents the reduction of seismic resistance in wooden houses due to its strong anti-loosening effect and its ability to follow wood shrinkage (aging contraction). It prevents the decline in seismic resistance of wooden structures caused by aging deterioration due to wood shrinkage and vibrations from earthquakes and typhoons. Installation is simple; just insert the bolt and tighten the nut to exhibit a powerful anti-loosening effect. The movement of the magic ring is key. Columns and Beams Structural materials such as columns, beams, and braces form the framework of the building, providing rigidity and strength to withstand loads and forces acting on the building. In the case of the "traditional method," known as "wooden frame construction," bolts and nuts are used for connections between beams and between beams and columns. If the joints (bolts and nuts) loosen due to aging deterioration, the rigidity of the structure itself is compromised.
