Product Description

Product Description

Blind Hole Type Wire Screw Sleeves, also known as Wire Thread Inserts for Blind Holes or Blind Hole Wire Screw Sleeves, are special fasteners used to strengthen or repair threads in blind holes. This type of screw sleeve is mainly made of high-strength stainless steel wire or alloy steel wire wound into a spiral structure, with good elasticity and abrasion resistance.
Structure and principle
Structure: Blind Hole Wire Sleeves are usually made of single or multi-stranded wire wound into a spiral shape on the outer surface, which can be elastically attached to the inner wall of the hole, and the inner surface forms a standard thread, which is used for screwing in screws or bolts.
-Principle: The screw sleeve relies on its own elasticity to make close contact with the inner wall of the screw hole, providing additional support and strength. When screws or bolts are screwed in, the inner threads of the screw sleeve are matched with them, thus enhancing the stability and reliability of the connection.
Features and Benefits
-Increased strength: Screw jackets significantly increase the tensile strength and fatigue life of threaded connections.
-Repair threads: can be used to repair worn or damaged threads and restore the original fastening function.
-Reuse: Even if the screw sleeve is removed, it can be installed again, improving the utilisation of materials.
-Anti-corrosion: Stainless steel is used in most cases, which has good corrosion resistance.
-Wide adaptability: Suitable for a wide range of material substrates, including soft metals, plastics, wood, etc.
-Easy to install: special installation tools are available for quick installation.
Specification and Size
-Size range: from very small diameter miniature screw bushings to larger diameter industrial grade screw bushings are available, covering thread sizes from M2 to M16 and even larger.
-Length: Depending on the depth of the blind hole, the length of the screw sleeve will vary to ensure adequate support.
-Standard: Follow international or national related standards, such as GB/T 24425.2-2009 (China National Standard), etc.
Application Areas
-Aerospace: Used in the fastening of aircraft components to ensure the safety of the connection.
-Automotive manufacturing: used in threaded connections in engine, body and other parts to improve durability.
-Electronic equipment: used as thread reinforcement in small equipment.
-Heavy machinery: Used in equipment subjected to heavy loads to increase the load-bearing capacity of threads.
-Construction industry: used in the connection of prefabricated components to enhance the stability of the structure.
Precautions for use
-Correct installation: Use special tools to install, avoid damaging the screw sleeve or screw hole.
-Material Matching: Select the material of the screw sleeve that is compatible with the base material to avoid galvanic corrosion.
-Periodic inspection: For frequently used connectors, the condition of the screw sleeve should be inspected periodically, and the worn-out screw sleeve should be replaced in time.
