Product details
Description
Upgrade your 3D printing and plastic assembly projects with the Zruosiniy 400 Pieces Threaded Inserts Brass Heat Set Kit. Designed specifically for thermoplastic materials including PLA, PETG, and ABS, this comprehensive metric assortment provides reliable, high-strength metal threads inside printed enclosures, functional prototypes, and custom housings.
Each insert is crafted from solid brass, offering superior thermal conductivity that allows the nut to melt cleanly and evenly into a pilot hole using a standard soldering iron. The exterior features a deep, precision-angled knurled pattern that locks firmly into the surrounding plastic once embedded, effectively resisting rotation and high pull-out tension under repeated mechanical stress.
With 15 distinct metric variations ranging from M2 to M6, this kit covers virtually every standard hardware requirement for makers, engineers, and hobbyists. All four hundred pieces are neatly sorted and securely housed inside a compartmentalized, labeled storage box, ensuring you can quickly identify and grab the exact size you need without interrupting your workflow.
Say goodbye to stripped threads and loose connections, and give your custom builds professional-grade durability.
How to use
- Drill or design a CAD pilot hole slightly undersized for your specific insert outer diameter.
- Set your soldering iron temperature approximately 50 degrees Celsius to 100 degrees Celsius above your plastic printing temperature, around 240 degrees Celsius for PLA.
- Press straight down perpendicular to the surface gently until the brass insert sits completely flush with the plastic.

FAQs
What size hole should I use for threaded inserts in 3D printing?
You should design or drill your CAD pilot hole slightly undersized based on your specific insert outer diameter. For example, standard M3 inserts typically require around a 4.0 millimeter hole depending on the manufacturer specifications.
What plastics are compatible with these brass heat set inserts?
These brass knurled inserts are fully optimized to work seamlessly with PLA, PETG, and ABS thermoplastic materials, providing a secure and durable bond for all standard 3D printed projects.
How do you install heat set threaded inserts into plastic parts?
Heat set inserts are installed by placing the brass nut over a properly sized pilot hole and pressing down gently with a heated soldering iron. The thermal energy melts the surrounding thermoplastic, allowing the knurled exterior to lock permanently into place.
