Fasteners include: bolts, studs, screws, nuts, washers, and pins. Locking or galling occurs with fasteners made of stainless steel, aluminum and titanium alloys. Fasteners are inherently corrosion resistant, forming a thin oxide layer on the metal surface to prevent further corrosion if the surface is damaged.

When a stainless steel fastener locks, the pressure and heat generated between the teeth can destroy the oxide layer, causing the metal threads to clog or cut off, thus jamming. When this happens, the stainless steel fastener is completely locked and can never be removed or remain locked. This blocking-shearing-bonding-locking sequence usually occurs within seconds, so this type of fastener should be properly recognized when in use so that this phenomenon can be prevented.

Compared with carbon steel, stainless steel fasteners have high temperature resistance and corrosion resistance, stainless steel is also widely used in our lives, what are the advantages of stainless steel in the end?

The advantages of stainless steel fasteners

✔️The first point, high temperature resistance

Stainless steel fasteners high temperature resistance: It is because the stainless steel fasteners themselves are hard enough, after the production and processing of fasteners have a strong anti-oxidation ability, and it is also able to work normally under high temperature, so it will not be too much interference from high temperature. If the stainless steel fasteners can be used after manufacturing while passivated before, then it will become better.

✔️The second point, the electric negative rate

Stainless steel fasteners electric shade rate: the physical properties of stainless steel fasteners have a very high electric shade rate, so compared with carbon steel wire, stainless steel fasteners than its electric shade rate a full five times higher. After testing we have concluded that there is an expansion coefficient in the fastener, if the higher the temperature, then the expansion coefficient of stainless steel fasteners will also gradually increase with the increase in temperature.

✔️The third point, the force capacity

Stainless steel fasteners force capacity: for stainless steel fasteners, the force capacity to carry the load is medium, even if it is not comparable to high-strength bolts, but the force capacity of stainless steel fasteners can also meet the daily needs of people.

✔️The fourth point, mechanical properties

The mechanical properties of stainless steel fasteners: in the mechanical properties, most of us understand that, many fasteners mechanical properties are and stainless steel wire has a lot to do with. For example: will not rust, very high corrosion resistance, etc., these are with the nature of the stainless steel material itself has a great relationship, with the continuous development of fasteners, these mechanical properties can also become stronger.

What is the main use of fasteners?

Fasteners are mainly used in energy, electronics, electrical appliances, machinery, chemicals, metallurgy, molds, hydraulics and other fields. There are various fasteners on top of various machinery, equipment, vehicles, ships, railroads, bridges, buildings, structures, tools, instruments, chemicals, instruments and supplies. Fasteners are also known as the most widely used mechanical foundation parts.
