Description for SUS304 Wire Thread Inserts
Wire thread inserts are also known as thread inserts, stainless steel inserts, helicoil inserts, or thread sleeves, are internal threaded fasteners made by winding high-strength, high-precision wire with a diamond-shaped cross-section.
When installed in low-strength engineering materials such as aluminum alloys, zinc alloys, magnesium alloys, copper, plastics, and phenolic materials, they significantly improve thread strength, wear resistance, and service life.
◆ The standard material for commonly used wire thread insert sizes is SUS304 stainless steel.

Specific Applications of Wire Thread Inserts
Application 1: Product Assembly
Installing wire thread inserts into threaded holes of materials such as aluminum alloys creates high-strength, wear-resistant, and precision-standard internal threads.
Typical Applications: High-voltage switchgear, microwave communication equipment, automotive components, air separation equipment, radiators, and more.
Application 2: Thread Repair
When threading errors occur or internal threads are damaged, wire thread inserts can be used as a repair solution, providing an economical and effective way to restore the threaded hole.
Typical Application: Repair of stripped threaded holes in components, such as restoring threaded holes in injection molding machine plates.
Application 3: Thread Conversion
Wire thread inserts can be used to convert metric threaded holes to imperial threads, providing a convenient and quick solution.
Typical Application: Converting metric threads to imperial threads on imported or exported equipment and machinery when spare parts availability requires the change.
