Excellent quality at a very reasonable price – a must-have for any maker. ### ⭐⭐⭐⭐⭐ Thread inserts *by A***R on 6 April 2026* Got these for a 3d print i done and they work great and have used them for different jobs as well ### ⭐⭐⭐⭐ Good quality threads.But make sure to use the correct tool tip for melting. *by R***R on 3 August 2025* The product works as expected on the whole. However contrary to most advice, a special tool is needed to insert these correctly. An ordinary soldering iron tip that does not go all the way through the insert will push the insert into the plastic. However it will fill the insert with the melted debris making it difficult to screw a bolt into the insert without first clearing the blocked thread. ## Frequently Bought Together - HOLMOL Threaded Inserts for Plastic 360PCS, Heat Insert Assortment Set, Brass Metric Knurled Nuts M2 M2.5 M3 M4 M5 M6mm for 3D Printer Parts - HANGLIFE Soldering Iron Tips for Threaded Inserts M2 M2.5 M3 M4 M5 M6 M8, Heat-Set Insert Tips Compatible with Weller SP40NUS/Hakko FX-888D/900M/T18 Irons- Press Tool for Plastic 3D Printer Components - Soldering Iron Kit Electric, Soldering Iron 90W Welding Tools, Adjustable Temperature 180-480℃ Soldering Kit, Digital Portable Solder Iron Kit with 5 Solder Tips, Solder Wire, Mini Stand --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/693499171-threaded-inserts-for-plastic-360pcs-heat-insert-assortment-set-brass](https://www.desertcart.pt/products/693499171-threaded-inserts-for-plastic-360pcs-heat-insert-assortment-set-brass) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-07-07*
