Full threaded bolt is a type of fastener with threads machined along the entire length of the screw, widely used in various fields such as machinery, construction, and chemical engineering. The following is a detailed introduction:
• Structural features
Full threaded construction: From one end of the stud to the other, the entire body is filled with threads. Compared to partially threaded studs, the thread length is significantly increased, increasing the contact area with the nut or connected part.
Diverse forms at both ends: Common forms include equal length double head type, where both ends have external threads and equal lengths; There is also a different thread type with one end having coarse threads and the other end having fine threads, which can meet different connection requirements.
Rich diameter specifications: Metric specifications commonly include M3-M100 or even larger, while imperial specifications cover various sizes such as 1/4-4 inches, which can adapt to different loads and space limitations.
• Performance advantages
High strength and high load-bearing capacity: High quality alloy steel or stainless steel materials are often used, and their strength is enhanced through heat treatment processes. They can withstand large axial tensile and shear forces, ensuring the reliability of the connection.
Uniform force distribution: The fully threaded design distributes the load evenly throughout the entire bolt, reducing stress concentration, avoiding connection failure caused by local overload, and improving the stability of the connection structure.
Flexible installation: Nuts can be installed at any position according to actual needs, making it easy to adjust the spacing and position of connecting components, especially suitable for multi-layer or complex structure connections.
• Application scenarios
Industrial equipment manufacturing: used in heavy machinery, pressure vessels, pumps, valves, and other equipment to secure critical components and ensure stable operation under harsh conditions such as high pressure, high temperature, and vibration.
Building steel structure: In steel structure buildings, it is used to connect components such as steel beams and columns to ensure the integrity and stability of the building structure.
Automotive and Aerospace: In the assembly of automotive engines, aircraft engines, and fuselage structures, high-precision and high reliability connections are achieved to meet the requirements of lightweight and high-performance.
• Installation and maintenance
Installation points: During installation, ensure that the bolts are screwed vertically into the connected parts, use appropriate tools to tighten the nuts to the specified torque, and avoid loose connections or damaged bolts due to uneven tightening force.
Maintenance inspection: Regularly check the connection parts of the bolts for looseness, corrosion, or deformation, replace damaged bolts and nuts in a timely manner, and ensure the safety of the connection system.
