As the loosening rotation is suppressed by the magnetic force formed on the bolt & nut, the increase of the loosening torque increases the frictional force, and the larger the loosening torque, the more the friction coefficient increases and thereby the loosening is prevented.
• Loosening prevention
By forming a groove in the flange surface of the bolt and nut and inserting a magnet into the groove, it is possible to prevent the loosening by suppressing the loosening force by increasing the frictional force in the vibration impact and the JUNKER axial performance test and the NAS3350 vibration test have proven their anti-loosening performance.
• Quick fastening
The bolt and nut with magnetic force is attached to the joining material, which makes it unnecessary to use auxiliary manpower when working at a high place, so that even one person can quickly fasten.
• Safe operation
Since the bolts and nuts do not fall during the fastening operation at the high work site, personal injuries are prevented and the safety of the workplace is improved.
A. Reduce labor cost by about 20% by time saving through quick fastening
B. Reduce material cost by about 5% through loss prevention of bolt & nut
