Truss head self drilling screws

Truss screws are screws with specific shapes and functions, typically used to connect various components of a truss structure. They are widely used in mechanical engineering, construction engineering, aerospace and other fields. Their shape and size usually make them more suitable for truss connections.

Truss screws are usually made of high-strength alloy steel, stainless steel, titanium alloy and other materials to ensure that they can withstand high loads and will not have corrosion or other problems during long-term use.

Truss screws are indispensable connectors in truss structure design. They have the following functions:

1. Connect the various components of the truss structure;

2. Enhance the stability and robustness of the truss structure;

3. Provide highly reliable connections in various engineering applications.

The key factors in selecting suitable truss screws are load, stress, and environment. The greater the clamping force, the larger the screw size needs to be selected to meet the requirements under high load conditions. In marine, corrosive, and other harsh environments, it is necessary to choose high-strength materials such as stainless steel or titanium alloys that meet the requirements.

Truss screws are one of the main components connecting truss structures, commonly used in building platforms, stages, exhibition stands, and other occasions. Its specifications include thread diameter, length, pitch, material, and other aspects.

① Thread diameter

The thread diameter of truss screws can be divided into ordinary and fine thread types, generally M8, M10, M12, etc. The fine thread type is slightly adjusted on the basis of the ordinary type to enhance the stability of the connection.

②Length

The length of truss screws is generally between 20mm and 200mm, which is related to the height of the truss structure and needs to be selected according to the actual situation.

③ Thread pitch

The pitch of truss screws is generally 1.5mm~2.0mm, and the smaller the pitch, the stronger the connection.

④ Material

There are generally two types of materials for truss screws: carbon steel and stainless steel. Stainless steel has a longer service life and better corrosion resistance, but the corresponding price is also higher.
