Bolt screw sleeve specification material performance use
A bolt sleeve is a special fastener used to strengthen or repair internal threaded holes, especially in applications where the strength of threaded connections is required. Below is a detailed description of bolt sleeve specifications, materials, performance and uses: Specifications Bolt Sleeve specifications cover metric and imperial sizes from small to large, including but not limited to M2 to M100 or #4-40 to 1-1/2 UNC. Their length and pitch are determined according to the specific application requirements, in accordance with relevant international standards such as ISO, ANSI, etc., to ensure the accuracy and interchangeability of the thread.
Material:
Carbon steel: Suitable for general industrial applications, with good strength and cost effectiveness.
• Stainless steel: 304 or 316 stainless steel is commonly used, which has excellent corrosion resistance and is suitable for Marine, chemical and other corrosive environments.
Titanium alloys: Titanium alloys are ideal for applications requiring high strength, light weight and corrosion resistance, such as aerospace.
Features:
• High strength connection: The bolt design enables the sleeve to form a stronger mechanical connection with the base material, improving the bearing capacity of the threaded hole.
• Anti-vibration: the bolt sleeve can maintain good fastening performance under vibration environment to prevent thread loosening.
• Repair damaged thread: For damaged or worn thread holes, the bolt sleeve can be used as a repair means to restore the function of the thread hole.
• Quick installation: The installation process of the bolt sleeve is relatively simple, and the installation can be quickly completed by special tools to improve work efficiency.
