Today, we received an inquiry from a customer who wanted to  phillips truss head machine screws , but asked that it be non-toxic and harmless, because it is used in medical devices. As a professional manufacturer of titanium screw, we immediately recommended to him make phillips truss head machine screw with TA2 pure titanium. “Titanium” is a pure metal, which is characterized by high melting point, light material, strong corrosion resistance and solid electroplating. What are the advantages of making pure titanium # phillipstrussheadmachinescrews ? First of all, it is non-toxic, harmless and pollution-free we mentioned before ,and it has a strong corrosion resistance. Pure titanium screw is more than medical, military, electroplating, high-end tableware, luxury goods, glasses, luggage and other industries. Shenzhen Shi Shi Tong metal products professionally customize pure titanium TA2 screws, specifications can be customized between M1-M10. The best non-toxic and harmless m...

Frequently, customers will give the screw diameter and length, material, quantity, and then say that the specifications of this  flat head security screw  will be produced according to your standards. The  flat head  #securityscrew  in the flat head has the meaning of the C head in Chinese, and the meaning of the countersunk head. If you just describe it and don’t give a picture, then we can’t determine what the head shape of the screw is. If it is a countersunk head screw, then you need to know if the customer has a requirement for the head angle of the screw. Different head angles, the size of the head is different. If it is a C-headed Phillips screw, the specifications of this screw are not standard. If the head size is too small, it may not be able to tighten. So if it is a countersunk # flatheadsecurityscrew , you can give the standard number, or tell us what the required countersunk angle is, we will give the size to confirm. If it is a flat head se...

Inside the anti-theft screw, there are many   torx tamper proof screws . However, because of the use of some, some common standard torx tamper proof with anti-theft screws are basically stocked in the electronic city. Therefore, the slot type screws are generally not burglarproof. However, some customers say that although this type of trough is very common, I still want this type of trough. How can I make my torx tamper proof screws unique and burglarproof? The groove type of the # torxtamperproofscrews  is still somewhat different. If the customer wants the common type of anti-theft screw with a plum blossom column, if you want to prevent theft, it is usually changed in the size of the column, or the size of the six lobe is changed, do not change to the standard. If the customer does not specify which kind of torx, then you can recommend the customer to use the anti-theft screws with five torx, or the anti-theft  #screws  of the seven torx. This kind of  t...

Why do some  stainless truss head screws  flawed? Screw manufacturers are more or less embarrassed in the process of producing screws, but the probability of smashing the stainless steel truss head screws is higher. Why? Many people will ask why the  stainless  #trussheadscrews  are flawed. What is the cause? The stainless steel truss head screws has flaws because the head of the truss head screw has a relatively large diameter, and the stainless steel material has a high hardness, which is liable to cause headshot in the production process. The main reason is that production technology operations are not reasonable. Another reason is that the quality of the raw materials is too poor, there are impurities, and the purity is not enough. As a result, the stainless steel truss head screws are flawed, and the screws are smashed after the molding, because the yield strength of the head cannot withstand the internal stress. It is. Therefore, in order to avoid t...

What is the role of the flat head machine screws ? Presumably, many friends don’t know what the flat head machine screws do. Let's take a look. First introduce to you what is a flat head machine screws, the so-called flat head screw, as the name suggests is that the surface mounted on the part is flat, there can be no raised areas. The head of the flat head screw will have a flat angle of 90 degrees and is usually mounted on the surface of the machine. Since the screw is not very fixed, it can be used on multiple mechanical parts. What is the function of the flat head machine screws? In fact, it is not so mysterious. flat head machine screws are parts that are indispensable for everyday life or industrial manufacturing by connecting two or more parts. The difference between a flat head screw and other screws is that the head will sink into the assembled equipment when in use. It should be noted that in the process of use, it is not possible to directly ream the hole with a ...

In the carburizing process of countersunk self tapping screws , the deep carburizing process is different. For workpieces with a carburized layer depth greater than 1.0 mm, such as automobile gears, the carburized layer depth and the carbon concentration distribution of the layer, even the layer The depth of the over-eutectoid layer and the eutectoid layer may have certain requirements. In order to ensure a high carburization rate, such parts are often diffused using an atmosphere having a carbon potential of 0.7% C-0.8% C after high carbon potential carburization. In order to reduce the distortion caused by direct quenching after carburizing and reduce the martensite and retained austenite grade, the process of furnace cooling to 820-860 ° C isothermal and then quenching is required after the end of the diffusion phase to ensure that the layer and the core are Qualified hardness and good microstructure. The requirements for carrier gas and rich gas in this carburizing process are diff...

Taptite screw , its thread is a common thread with a curved triangular cross section. The thread surface also has a high hardness. Therefore, when connecting, the screw can tap the internal thread in the bottom hole of the connected piece. Thereby forming a connection. This type of screw features low screw-in torque and high locking performance.
