Fastener screws are a commonly used type of connector, typically composed of screws and nuts, mainly used to connect plates, thin-walled components, and also applied in scenarios such as pipelines. The following is a detailed description of the fastening screws:
1, Specification and size
• Diameter: usually refers to the inner diameter of the thread, usually measured in millimeters (mm).
• Length: usually refers to the length of the screw, usually measured in centimeters (cm).
• Thread quantity: Refers to the number of threads that determine the available length, strength, and other aspects of the screw.
2, Thread specifications
Ordinary thread: With a wide pitch, it is easy to produce anti slip grooves on both sides of the thread, which can improve the twisting force and connection strength.
Fine thread: With a smaller pitch, the top of the thread is smoother and less prone to slipping, which can improve the tightness and reliability of the connection.
3, Common types
M6 screw: It has strong versatility and can be used with different screw heads (such as small countersunk heads and semi-circular heads) to achieve different results.
Small countersunk screws: easy to insert into the groove, but with a small force surface, there is a risk of loosening.
Half round head screws: Especially thin ones, they can completely cover the anti slip patterns of the fasteners, making them more sturdy and secure when tightened.
Stainless steel fastener screws: corrosion-resistant, high strength, slightly higher price, but high durability.
4, Selection factors
When choosing fastener screws, the following factors need to be considered:
The material and thickness of the object to be connected.
The shape and size of the object to be connected.
The specifications, size, and thread type of the fastener screws.
In summary, although fasteners and screws are small, they play a significant role. When selecting and using, various factors should be comprehensively considered to ensure the firmness and reliability of the connection.
