M4×4mm Thread Inserts Brass Heat Insert 50Pcs
The Brass Threaded Inserts M4 × 4 × 6.3 mm (Short) are compact heat-set nuts for M4 thread applications in 3D printed components with limited installation depth. The short height of 4 mm with an outer diameter of 6.3 mm makes this version the right choice when M4 screws are needed but there is not much wall thickness available in the printed part. The knurled outer surface anchors itself in the molten plastic during melting and reliably resists both pull-out forces and torques.
Recommended Accessories:
- C245 Soldering Iron Heat-Set Insert Helper Insert M2-M8
- Soldering Iron Heat-Set Insert Helper Insert M2-M8
- Threaded Insert Press Kit with Soldering Iron and Accessories
- Threaded Insert Press Kit Pro with Soldering Iron and Accessories
Features:
- Short height of 4 mm enables M4 threaded connections even in printed parts with limited available installation depth
- Brass material with high thermal conductivity allows fast and even melting into all common FDM thermoplastics
- Knurled outer surface locks in form-fit in the solidifying plastic and reliably resists pull-out and torque loads
- Installation with standard soldering station or heat-set press – no thread cutting or reworking required
- Compatible with M4 screws (ISO-metric), suitable for PLA, PETG, ABS, ASA, PC, and other thermoplastics
- 50 pieces per pack for prototyping, serial applications, and repair work
Application Examples:
- 3D printed mounts, enclosures, and mechanical assemblies with M4 screws and limited installation depth
- Mounting points for heavier components such as motors, profiles, and rails on 3D printers
- Repair of plastic parts with damaged M4 threads through subsequent melting
- Prototyping in mechanical engineering and product development
