With the help of heat from a soldering iron or ultrasonic, the insert nuts are simply embedded in a blind- or through hole - FIXED HOLD WITH EASY APPLICATION: Thanks to the geometry of the threaded sleeve, the threaded sleeve holds it firmly in the pressure part. The opposing spiral-shaped knurled nuts ensure a balanced high tightening and loosening torque, as well as a high tightening force. The guide has made insertion much easier - STABLE & LONG-LASTING THREAD INSERTS: The inserts with internal thread brass, which ensures optimum corrosion resistance and thermal conductivity. This means that each insert nut can be used for a long time and is easy to use. The reusability of the insert nut is also possible by carefully removing them from the pressure part when they are no longer needed - SUITABLE FOR A VARIETY OF PLASTICS: The inserts are designed for all thermoplastics. For example, the knurled nuts hold in PLA, PETG, ABS, PPS, PP and many more. As soon as the plastic of the part around the brass sleeve cools and hardens, the threaded sleeve is firmly anchored - PRACTICAL THREAD INSERT SET: The ruthex thread insert set are lead free RX-M3x5,7 consists of 100 insert nuts with M3 internal thread and a length of 5.7 mm. The threaded sleeves can be inserted by ultrasonic and heat embedding ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08BCRZZS3 | | Best Sellers Rank | #1,244 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #1 in Nut Inserts | | Brand | ruthex | | Color | Metric Threaded Insert | | Compatible Groove Diameter | 3.5 millimeters | | Customer Reviews | 4.8 out of 5 stars 1,484 Reviews | | Drive Style | Spline | | Exterior Finish | Brass | | Fastener Type | Insert | | Finish Types | Brass | | Grade Rating | Industrial | | Inside Thread Size | M3 | | Item Diameter | 3 millimeters | | Item Dimensions | 4.72 x 3.54 x 0.39 inches | | Manufacturer | ruthex | | Material | Brass | | Material Type | Brass | | Metal Type | Brass | | Model | GE-M3x57-001 | | Number Of Items | 100 | | Number of Pieces | 100 | | Part Number | GE-M3x57-001 | | Screw Head Style | Flat | | Set Name | ruthex M3 Threaded Inserts - 100 Pieces RX-M3x5.7 | | Size Name | M3x5.7 (100pcs) | | Thread Class | Class 2A | | Thread Coverage | Fully Threaded | | Thread Size | M3 | | Thread Style | Right Hand | | Thread Type | Straight | | Unit Count | 100 Count | ## Product Details - **Color:** Metric Threaded Insert - **Exterior Finish:** Brass - **Fastener Type:** Insert - **Material:** Brass - **Thread Size:** M3 ## Images ![GE-M3x57-001 - Image 1](https://m.media-amazon.com/images/I/717sikDXLoL.jpg) ![GE-M3x57-001 - Image 2](https://m.media-amazon.com/images/I/81pKWAOJdoL.jpg) ![GE-M3x57-001 - Image 3](https://m.media-amazon.com/images/I/717LH8yMKsL.jpg) ![GE-M3x57-001 - Image 4](https://m.media-amazon.com/images/I/71od3QUANkL.jpg) ![GE-M3x57-001 - Image 5](https://m.media-amazon.com/images/I/71ntgYcJImL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Customer Reviews ### ā­ā­ā­ā­ā­ High-Quality Heat Inserts *by M***S on February 14, 2026* Overall, Iā€™m very happy with these heat inserts.
