マイクロファスナー List of Products and Services

This is an embedded nut used as a molding material for resins such as plastic. It is primarily used for fastening purposes by being press-fitted into molded products after embedding through heat or press, or by being incorporated during the molding process using screws. In the case of plastic (resin), there are issues such as insufficient strength when directly joined with screws, making it prone to breakage. Using insert nuts in such cases provides high strength and allows for stable product assembly. Additionally, we can produce and sell both domestically and internationally, and we respond quickly, including design technical support. 【Features】 ■ Abundant standard products ■ Custom production available ■ Supports thin designs (proven delivery to thin products such as mobile phones and computers) ■ All products comply with RoHS (solving issues such as "contamination with cutting chips" and "high defect rates") *For more details, please contact us or download and view the catalog.

Are you having trouble with strength testing during the mass production of insert nuts? Our company has injection molding molds available, so you can simply provide the resin materials (pellets) you plan to use, and we can conduct strength tests. We will mold the parts and embed the insert nuts. We can perform tensile strength tests, torque strength tests, and even visual inspections. 【Insert Nuts for Plastic】 ■ Types of Plastic: Thermoplastic Resin, Thermosetting Resin, Polycarbonate ■ Insertion Methods: Hot press after molding, Cold press after molding, Insert during molding *This service is a paid service. *For more details, please download the PDF or feel free to contact us.

Insert nuts are used primarily for fastening purposes by utilizing screws after being press-fitted into resin (plastic) molded products. They are used in various fields, such as automobiles and machine tools, in diverse locations. That said, insert nuts come in a wide range of standards and sizes, and it is often unclear which one to use. Therefore, we have created a document summarizing "Tips for Selecting Insert Nuts." We are also offering the "Comprehensive Catalog of Insert Nuts," which includes over 150 sizes and reference strength data that we handle!
