Stainless steel fasteners We often encounter the problem of stainless steel standard parts locking. So why do stainless steel fasteners always lock up? What is the reason! Why haven't you heard that the standard parts of iron do not lock up? This may be seen from the two materials of stainless steel and iron. Stainless steel standard parts are relatively soft and have good ductility. The hardness of stainless steel standard parts is SUS316. Compared with the hardness of iron standard parts, they are softer than iron standard parts of 8.8. Fastener users often reflect: Why do stainless steel fasteners sometimes lock up, and similar phenomena do not often occur when using carbon steel fasteners, are stainless steel fasteners softer and carbon steel? Why are fasteners relatively hard? That's right! There is a fundamental difference between stainless steel and carbon steel. Stainless steel has good ductility, but its hardness is somewhat different from carbon steel.

"Stainless steel fasteners" is a specific term concept covering a wide range of products. Stainless steel fasteners are often used for fastening of more expensive machine parts because of their beauty, durability, and strong corrosion resistance. With the progress of society, higher requirements have been put forward for stainless steel standard parts.

Today we will learn the terms related to metallurgy and heat treatment:

The main purpose of surface treatment is aesthetics and corrosion protection. Because the main function of the fastener is to fasten parts, and the surface treatment also has a great impact on its fastening performance. Therefore, when selecting the surface treatment process, factors such as the torque and consistency of the pre-tightening force of the fastener must be considered.

Self tapping screws are mostly used for the connection between thin metal plates. When connecting, first make a threaded bottom hole for the connected piece, and then screw the self-tapping screw into the threaded bottom hole of the connected piece. So what are the characteristics of self tapping screws? Next, I will introduce the characteristics of self tapping screws in detail for everyone.

The head of the self-tapping screw is pointed and can be used normally without drilling. Widely used in doors and windows and iron sheet. So do you know what are the forms of self-tapping screws? Let's take a look at the thread types of self-tapping screws together.

socket cap screws are required on many machines and equipment, and they also play a large role. Anti-corrosion of hexagon socket is more important, so how to prevent corrosion of socket cap screw? How to remove the worn socket cap screw? The following manufacturers of socket cap screws will tell you how to remove the socket cap screws and how to prevent corrosion. I hope it will be helpful to everyone.

Pan-head screws and round-head screws are often difficult to distinguish because of their similar appearances. In fact, different screw head types have different uses. Below we introduce the difference between round head screws and pan head screws, I hope it will be helpful to everyone.

The head of the self-tapping screw is pointed and has threads. It can be used when drilling is required. It is mainly used in wall panels, furniture, roofs and other places. The following describes the types of self-tapping screws for everyone, I hope to help you.
