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-M3x5x4 consists of 100 insert nuts with M3 internal thread, width 5 mm and a length of 4.0 mm. The threaded sleeves can be inserted by ultrasonic and heat embedding. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CDH36ZMX | | Best Sellers Rank | #820 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #1 in Nut Inserts | | Brand | ruthex | | Color | Metric Threaded Insert | | Compatible Groove Diameter | 3.23 Millimeters | | Customer Reviews | 4.8 4.8 out of 5 stars (4,048) | | Drive Style | Spline | | Exterior Finish | Brass | | Fastener Type | Insert | | Finish Types | Brass | | Global Trade Identification Number | 04260528721283 | | Grade Rating | industrial | | Inside Thread Size | M3 | | Item Diameter | 3 Millimeters | | Item Dimensions | 4.72 x 3.54 x 0.2 inches | | Manufacturer | ruthex | | Material Type | Brass | | Metal Type | Brass | | Model | GE-M3x5x4-001 | | Number of Pieces | 100 | | Part Number | GE-P-D | | Size Name | M3x5x4 VORON (100 pcs) | | Thread Class | Class 6H | | Thread Coverage | Fully Threaded | | Thread Size | M3 | | Thread Style | Right Hand | | Thread Type | Standard | ## Product Details - **Color:** Metric Threaded Insert - **Exterior Finish:** Brass - **Fastener Type:** Insert - **Material:** Brass - **Thread Size:** M3 ## Images ![ruthex M3 Threaded Inserts VORON - 100 Pieces RX-M3x5x4 Brass Heat Set Insert for Plastic Parts - Metric knurled Nuts - Insert by Heat into 3D Printing Components - Image 1](https://m.media-amazon.com/images/I/71lnC9E0vnL.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.
