Reasons For Loose Bolts In DIN 933

The real cause of DIN 933 bolt damaged is looseness: After DIN 933 bolts are loose, infinite kinetic energy mv2 is generated. This infinite kinetic energy directly affects fasteners and equipment, resulting in fasteners damage. After the fastener is damaged, the equipment cannot Operate under normal conditions further damages the equipment.

Fasteners subjected to axial forces, the threads are damaged, and the bolts are broken.

Fasteners subjected to radial forces cut bolts and bolt holes were novelized.

The thread anti-loose method of the excellent anti-loose effect is the basis of solving the problem:

The most advanced and effective method of locking is now DIN 933 bolt locking.

The threads together feature left- and right-handed threads. It can work with both left-handed and right-handed threads. 1 Two nuts with different rotation directions are used when connecting. The nuts on the working support surface are called fastening nuts, and the nuts on the non-supporting surface are called to lock nuts. Pre-tighten the tightening nut before using, and then tighten the lock nut.

Under the condition of oscillation and impact, the tightening nut will loosen, but because the loosening direction of the tightening nut is the tightening direction of the lock nut, the tightening of the lock nut just prevents the loosening of the tightening nut. As a result, the fastening nut cannot be loosened.
