What are the dangers of loose fasteners such as high-strength bolts?

What are the dangers of loose fasteners such as high-strength bolts?

When using an electric wrench to fasten high-strength bolts, be sure to fasten them according to the bolt torque method. Fasteners such as bolts not only play a role in connection, but also play a role in fixing and protecting the equipment. The loosening of fasteners will increase the vibration of the parts or equipment, increase the relative motion, and increase the gap, which will result in the breakage of fasteners and damage to the workpieces, and even lead to casualties and other safety accidents. 　　For example, on September 13, 2012, Wuhan, “East Lake Park” project C 7-1 building site, the lift in the process of rising suddenly out of control, straight to the top of the 34th floor (100 meters from the ground), the steel rope breaks, the loss of rope constraints on the lift after the free fall straight to the ground, resulting in the death of 19 people. After investigation, the causes of the accident included the nuts of the two stressed bolts on the right side of the four connecting bolts at the two standard section connections of the lift guide rail falling off, damage to the safety guards of the lift, unlicensed operation of the workers and overloading of the personnel, etc. The accident was caused by a number of factors, including the loss of fasteners such as bolts, nuts and other fasteners. 　　Factors such as missing bolts, nuts and other fasteners, loosening, dislodging and non-self-inspection and acceptance of the illegal use of factors is a major cause of accidents. 　　Therefore, when tightening bolts, we can use HANPU electric wrenches. They are small and easy to use, and the torque value can be adjusted precisely to make the bolts reach the tightening strength.

[Popular Knowledge] Is it better to tighten the bolts as much as possible?

[Popular Knowledge] Is it better to tighten the bolts as much as possible?

The use of bolts is very wide, from small watch movements to various types of engineering equipment, the smallest screw diameter can be calculated in millimeters, the largest can be calculated in centimeters and decimeters. Bolt we usually call it screws, bolt material is usually divided into steel screws, iron screws, alloy screws, plastic screws, etc., in the use of the bolt is screwed the tighter the better?
