SERPLAST C Expansion Insert Technology
The 40/C SERPLAST C Insert features an insertion by expansion design and provides a self-break effect, helping to resist screw loosening after installation. The insert is fitted into a moulded or drilled hole using simple pressure and, during screw tightening, expands within the parent material to create a secure mechanical fixing and durable threaded connection.
SERPLAST Type C inserts are supplied with a collar, which assists with positioning and retention within the plastic component. They are suitable for use in both thermoplastics and duroplastics, making them a versatile solution for a wide variety of plastic assembly applications.
The insert provides a strong, wear-resistant metal thread in plastic materials with excellent performance in both pull-out and torque resistance tests. Installation can be completed after moulding, requiring no specialist powered equipment for manual assembly applications.
For improved alignment and installation accuracy, we recommend using the SER 1 Manual Installation Tool. This tool is particularly suitable for small production runs and maintenance applications, helping to ensure correct positioning of the insert within the prepared hole.
Installation Process
- Position the SERPLAST insert into the moulded or drilled hole.
- Apply simple pressure to locate the insert.
- Tightening the mating screw causes the insert to expand within the material.
- The expansion creates a secure fixing and produces the SERPLAST self-break effect, helping to prevent screw loosening.
When using the SER 1 installation tool:
- Position the insert over the prepared hole.
- Insert the tool's centering nipple into the thread of the SERPLAST insert.
- Apply a light hammer tap to the top of the tool.
- The insert is driven accurately into the plastic component.
