With the help of heat from a soldering iron or ultrasounds, the knurled insert nuts are simply embedded in a blind- or through hole - FIRM HOLDING WITH EASY APPLICATION: The threaded insert nut holds firmly. The knurled nuts have spirals in opposing directions that ensure tightening and loosening torque, as well as a high tightening force. The insertion has been greatly simplified - STABLE & LONG-LASTING THREAD INSERTS: The inserts with internal thread brass, which ensures optimum corrosion resistance and thermal conductivity. This means that each 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 female threaded sleeve is firmly anchored - PRACTICAL THREAD INSERT SET: The ruthex threaded inserts set are lead free and RX-M2x4 consists of 70 insertable nuts with M2 internal thread and a length of 4 mm. The threaded sleeves can be inserted by ultrasonic and heat embedding ## Technical Specifications | Specification | Value | |---------------|-------| | Material | Brass (lead-free) | | Fastener Type | Insert | | Thread Size | M2 | | Exterior Finish | Brass | | Colour | Threaded Insert | | Metal Type | Brass | | Finish Type | Brass | | Brand | ruthex | | Item dimensions L x W x H | 12 x 9 x 0.5 Centimeters | | Thread Type | ISO Metric | | Inside Thread Size | M2 | | Thread Style | Rechtsgewinde | | Thread Coverage | Fully Threaded | | Size | M2x4 (70pcs) | | Number of Pieces | 70 | | Set Name | 70 pieces | | Manufacturer | ruthex | | Country of Origin | USA | | Item model number | GE-M2x04-001 | | Product Dimensions | 12 x 9 x 0.5 cm; 10 g | | ASIN | B088QJG676 | ## Product Details - **Material:** Brass (lead-free) - **Fastener Type:** Insert - **Thread Size:** M2 - **Exterior Finish:** Brass - **Colour:** Threaded Insert - **Metal Type:** Brass - **Finish Type:** Brass - **Brand:** ruthex - **Item dimensions L x W x H:** 12 x 9 x 0.5 Centimeters - **Thread Type:** ISO Metric ## Images ![ruthex M2 Threaded Inserts - 70 Pieces RX-M2x4 Lead Free Brass knurled Nuts - Stable Thread Insert nut for Plastic Parts - can be Inserted by Heat into 3D Printer Parts Made of Plastic - Image 1](https://m.media-amazon.com/images/I/71rVQuYMPaL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Frequently Bought Together - ruthex M2 Threaded Inserts - 70 Pieces RX-M2x4 Brass Heat Set Insert for Plastic Parts - Metric knurled Nuts - Insert by Heat into 3D Printing Components - ruthex 7x Soldering Tips/Heat-Set Insert Tips - for Thread Inserts M2 / M2.5 / M3 / M4 / M5 / M6 / M8 - #2-56 / #4-40 / #8-32/ #10-24 1/4" and Soldering Iron Adapter 900M / T18 - Kadrick Metric Screw Assortment, 660 Pcs M2 Screws, M2*4mm/6mm/8mm/10mm/12mm/16mm,12.9 Grade Alloy Steel, Metric Hex Socket Head Cap Screws Nuts Washers Kit, Black Zinc Plated Anti Rust Upgrade --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kg/products/588324934-ruthex-m2-threaded-inserts-70-pieces-rx-m2x4-lead-free](https://www.desertcart.kg/products/588324934-ruthex-m2-threaded-inserts-70-pieces-rx-m2x4-lead-free) --- *Product available on Desertcart Kyrgyzstan* *Store origin: KG* *Last updated: 2026-05-17*
