Product Details
"1. Material strain hardening
During cyclic loading, materials may experience "cyclic strain hardening" or "cyclic strain softening", meaning that under constant amplitude cyclic strain, the stress amplitude will increase or decrease with the increase of the number of cycles. After several cycles, the stress amplitude enters a cyclic stable state. The Low-cycle fatigue of the lock nut is carried out under the condition that the strain is constant, and the strain hardening or softening of the thread piece will affect the maximum screw out torque. The alloy steel used for manufacturing lock nuts belongs to the cyclic strain hardening material. Material hardening will increase the elastic recovery force FN of the threaded piece and increase the tightening torque"
Countersunk, semi countersunk, 1200 countersunk, and semi countersunk rivets are mainly used in riveting situations where the surface needs to be smooth and the load is not significant. Flat headed rivets are used for riveting applications under general loads. Flat head and round head rivets are mainly used for riveting metal sheets or non-metallic materials such as leather, canvas, and wood. Large flat head rivets are mainly used for riveting non-metallic materials. Half hollow rivets are mainly used for riveting occasions with low load. Headless rivets are mainly used for riveting non-metallic materials. Hollow rivets have a light weight and weak head, and are used for riveting non-metallic materials with low load. Tubular rivets are used for non loaded riveting of non-metallic materials. Label rivets are mainly used for riveting nameplates on machines, equipment, etc.
Flat washers are mainly used to reduce pressure. When there is a large axial force when tightening some parts, it is easy to make the washer press into a disc shape. In this case, materials can be used and hardness can be increased to solve the problem.
