Can American made 304 stainless steel screws be used for anti-theft purposes? Which anti-theft effect is good?

Can we make anti-theft American made 304 stainless steel screws for outdoor facilities? What type of anti-theft effect is better for us?

For anti-theft screws, most of them are designed on the groove of the screw, but some customers may also make changes to the shape of the head. And what the user requested was to start with the groove type, asking us which one is less commonly used and rare in the market, and he wants this one.

We usually recommend customers to use pentagonal or quadrilateral straps, which are relatively rare. However, for customers who require anti-theft functions, we have also made it clear to them that this cannot achieve 100% anti-theft. Because others can directly find manufacturers who can match screwdrivers with your product and ask them to match the screwdriver according to this groove shape, so that the product will be opened; Another way is to violently break this product, so that this screw cannot prevent others.


The user said that he knows that anyone who wants to open it will do so, but screws with anti-theft performance can at least prevent others from accidentally opening it. After all, his product is placed outdoors, and some people will do various things when they are bored, and then open his product, which will cause safety hazards.

Detection of bearing operation process

Detection of bearing operation process

Rolling sound of bearings: A depth gauge is used to check the size and sound quality of the rolling sound of bearings during operation. Even if there are very slight scratches on the bearings, they will make abnormal and irregular sounds. The detector can effectively solve this problem. If the lubrication and installation parts are appropriate, the bearing temperature will rise sharply and the temperature will rise abnormally. At this time, the operation must be stopped and necessary preventive measures must be taken. Based on a large amount of experimental data, Table 4-1 lists the average temperature of the outer ring of the bearing during operation in various machinery for reference. Due to the influence of lubrication, speed, load, and environment on temperature, the median values in the table only represent approximate temperature ranges.

Bearing vibration: The damage or reaction of bearing vibration to bearings is relatively obvious, such as indentation, rust, cracks, peeling, wear, and other common problems can be clearly felt during testing. Therefore, the size of vibration can be measured by using a special vibration measurement device for bearings (frequency analyzer, etc.), and the specific abnormal situation cannot be inferred from the frequency. The measured values vary depending on the usage conditions of the bearings or the installation position of the sensors, so it is necessary to perform certain operations on the measured values of each machine in advance to determine the final data.

Bearing temperature: Bearing temperature. Some bearing temperatures can be measured, but if oil holes are used to directly measure the temperature of the outer ring of the bearing, it would be more appropriate. Usually, the temperature of the bearing slowly rises as the operation begins and stabilizes after a few hours. Due to the heat capacity, heat dissipation, speed, and rotation mode of the machine, the normal temperature of the bearings may vary. Thermal sensors can be used to monitor the working temperature of bearings at any time, and can be prepared and alerted before accidents occur.

What surface treatment methods can be used to improve the prevention of corrosion in fasteners?

/in /by

Fasteners are the most common components in mechanical equipment and play a crucial role. However, corrosion is the most common form of damage to fasteners during use. In order to prevent corrosion during use, we will perform surface treatment on fasteners after production. So, what surface treatment methods can improve fasteners to prevent corrosion? There are four main surface treatment methods to prevent corrosion of fasteners, and we can choose the most suitable method according to specific needs:

 

Our fastener products include: internal locking wire drawing rivets, external locking wire drawing rivets, seahorse rivets, double drum rivets, single drum rivets, lantern rivets, open type rivets, flower rivets, groove core pulling rivets, closed type rivets, rivet nuts, pneumatic riveting guns and related fasteners.

 

1、 Electroplating

Electroplating standard parts involves placing them in a metal solution and then applying an electric current to cover the surface of the standard parts with a layer of metal. There are many effects on this layer of metal, for example, we can choose different coating metals based on their different effects. If we want to prevent rust on the standard parts, we can electroplate zinc on the surface of the standard parts.

 

2、 Mechanical plating

Mechanical plating on standard parts is to allow metal particles to perform cold welding on the standard parts, ensuring some of the surface effects of the standard parts. Mechanical plating and electroplating are basically similar, but the methods we use are different, and the results can be said to be the same.

 

3、 Heat treatment

For standard parts, heat treatment is required on the surface. Some standard parts, such as drill tail screws, require a relatively hard surface, so drill tail screws can be heat treated to ensure that they have sufficient hardness. This is the reason for conducting heat treatment.

 

4、 Surface passivation

For the surface passivation of standard parts, passivation has two main functions: one is to enhance the hardness of the standard parts, and the other is to greatly reduce the oxidation effect of the standard parts. When conducting surface treatment processes for fasteners, we can choose the most suitable method based on specific circumstances and requirements. This way, fasteners can play a better role during use.
