Flat washer
The washer refers to the part between the connected piece and the nut. Generally, it is a flat metal ring for protecting the surface of the connected member from the nut and the pressure of the dispersing nut against the connected member.
Flat washer and spring washer
Spring washers are widely used in the bearing and non-bearing structures of general mechanical products. They are characterized by low cost and easy installation, and are suitable for parts with frequent assembly and disassembly. However, the spring washer has a low anti-loose ability.
Self-locking nuts
In general, the nut is loosened by vibration or the like during use, such as vibration. In order to prevent this phenomenon, a self-locking nut is invented. Self-locking nut Its function is mainly anti-loose and anti-vibration. For special occasions. Its working principle is generally self-locking by friction. Self-locking nuts are classified according to their functions. They are fitted with a nylon ring, a neck with a neck, and a metal anti-loose device. They are all effective torque type locknuts.
Nut anti-loose solution
Apply the nut anti-loose solution to the bolt tightening, and then screw the nut to achieve the anti-loose effect.
Double nut (left and right rotation)
It is also a good method to tighten and lock against a left-handed nut and a right-handed nut.
drilling and fixing Screw nut
In machinery, the pin is primarily used for assembly positioning and can also be used as an overload shear connection in a connection and relaxation level safety device. The types of pins are: cylindrical pins, tapered pins, perforated pins, split pins and safety pins.
