l Flush washer
Washer refers to the part between the connecting piece and the nut. Usually a flat metal ring used to protect the surface of the connected piece from nut abrasion and to disperse the pressure of the nut on the connected piece.
l Add flat washer and spring washer
Spring washers are widely used in load-bearing and non-load-bearing structures of general mechanical products. They are characterized by low cost, convenient installation and suitable for frequent installation and disassembly. But the spring washer has very low anti-loosening ability!
l Self locking nut
General nuts will loosen themselves due to vibration and other reasons during use, such as vibration. In order to prevent this phenomenon, self-locking nuts were invented. Self - locking nut its function is mainly anti - loose, anti - vibration. For special occasions. Its working principle is generally self-locking by friction. The types of self-locking nuts classified by function include those with nylon ring, neck closure and metal locking device. They are effective torque type lock nuts.
Self-locking nuts are difficult to screw due to their nature.
l Nut looser
Apply the nut anti-loosening solution to the place where the bolt is tightened, and then screw on the nut to achieve the effect of anti-loosening.
l Double nut (left and right screw) anti-loose
It is also a good method to tighten and prevent loosening by matching a left nut with a right nut.
l Screws and nuts are drilled and fixed with pins
In machinery, pins are used primarily for assembly positioning and can also be used as overload shear connections in connection and release level safety devices. The types of pins are: cylindrical pin, taper pin, hole pin, cotter pin and safety pin.
