The heights range from 3mm to 12mm. We hope you will like it. - Secure fixation: Our brass threaded inserts are made of high-quality brass and undergo precision processing, ensuring excellent heat conduction and corrosion resistance. Through testing, we have found that compared to straight-threaded inserts, the knurled threaded inserts provide stronger gripping strength and can withstand high levels of tensile force. - Clear labeling: Each specification has its own independent compartment in the plastic box, and we have attached labels with detailed annotations for key data, making it convenient to use. - Brand guarantee: Kadrick specializes in the production and development of fasteners. Our products have undergone rigorous testing, so you can use them with confidence. Additionally, we provide a 24-month after-sales warranty service. If you have any questions, please feel free to contact us. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0D5V3TZLB | | Best Sellers Rank | #2,325 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #3 in Nut Inserts | | Brand | Kadrick | | Color | yellow | | Customer Reviews | 4.8 out of 5 stars 406 Reviews | | Exterior Finish | Brass | | Fastener Type | Insert | | Finish Types | Brushed | | Grade Rating | commercial | | Inside Thread Size | M2, M3, M4, M5 | | Item Diameter | 2 Millimeters | | Item Dimensions | 2.7 x 5 x 0.72 inches | | Manufacturer | Kadrick | | Material | Brass | | Material Type | Brass | | Metal Type | Brass | | Number Of Items | 1 | | Number of Pieces | 420 | | Part Number | 047-HIK-M3-M5-420 | | Screw Head Style | Knurled | | Set Name | 520Pcs M2 M3 M4 M5 Threaded Inserts Assortment Kit | | Size Name | Kit M2-M5 520Pcs | | Thread Coverage | Fully Threaded | | Thread Size | M2 M3 M4 M5 | | Thread Style | Right Hand | | Thread Type | Iso Metric | | Unit Count | 520.0 Count | ## Product Details - **Color:** yellow - **Exterior Finish:** Brass - **Fastener Type:** Insert - **Material:** Brass - **Thread Size:** M2 M3 M4 M5 ## Images ![520Pcs M2 M3 M4 M5 Threaded Inserts Assortment Kit for 3D Printing Components, Metric Brass Knurled Nuts, Insert by Heat into Plastic Parts - Image 1](https://m.media-amazon.com/images/I/810+R97vN0L.jpg) ![520Pcs M2 M3 M4 M5 Threaded Inserts Assortment Kit for 3D Printing Components, Metric Brass Knurled Nuts, Insert by Heat into Plastic Parts - Image 2](https://m.media-amazon.com/images/I/71xN-aFNIrL.jpg) ![520Pcs M2 M3 M4 M5 Threaded Inserts Assortment Kit for 3D Printing Components, Metric Brass Knurled Nuts, Insert by Heat into Plastic Parts - Image 3](https://m.media-amazon.com/images/I/81v1cuuUsmL.jpg) ![520Pcs M2 M3 M4 M5 Threaded Inserts Assortment Kit for 3D Printing Components, Metric Brass Knurled Nuts, Insert by Heat into Plastic Parts - Image 4](https://m.media-amazon.com/images/I/71kKK9qNi2L.jpg) ![520Pcs M2 M3 M4 M5 Threaded Inserts Assortment Kit for 3D Printing Components, Metric Brass Knurled Nuts, Insert by Heat into Plastic Parts - Image 5](https://m.media-amazon.com/images/I/71mTq2RigjL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect for my 3D prints – makes them look way more professional! *by T***T on February 26, 2026* The Kadrick 520Pcs M2 M3 M4 M5 Threaded Inserts Assortment Kit is a must-have for anyone doing functional 3D prints.
