Part Number: MS21209
Function: INSERT / SCREW THREAD
MS21209 is screw thread insert. A screw thread insert, also known as a threaded insert or helicoil insert, is a type of threaded bushing or coil that is used to reinforce and repair threaded holes in materials like metal or plastic. It is commonly used in applications where the original threads have been stripped, damaged, or worn out, providing a new, durable, and stronger set of threads.
The screw thread insert is typically made of stainless steel, brass, or other materials, and it features internal threads that match the desired thread size. To install the insert, a hole is first drilled or tapped to a larger diameter than the original threaded hole. The insert is then inserted into the prepared hole and threaded in place. Once installed, the insert creates new threads that are more resistant to wear and can hold fasteners securely.
Screw thread inserts find applications in various industries, including automotive, aerospace, electronics, and manufacturing, where reliable and strong threaded connections are required. They are often used in engine blocks, cylinder heads, transmission housings, and other critical components that undergo high stress and repeated assembly and disassembly.
