M2.5×4mm Threaded Inserts Brass Heat Insert 100Pcs
The brass threaded inserts M2.5 × 4 × 4.6 mm are precision-manufactured heat set nuts for use in 3D-printed parts made of PLA, PETG, ABS, ASA, and other thermoplastics. The outer diameter of 4.6 mm and the height of 4 mm make these inserts the standard choice for M2.5 thread applications - particularly widespread in Raspberry Pi projects and SBC mounts. The knurled outer surface anchors itself when melting into the plasticized plastic and reliably resists both pull-out forces and torques.
Recommended Accessories:
- C245 Soldering Iron Heat Set Aid Threaded Inserts Insert M2-M8
- Soldering Iron Heat Set Aid Threaded Inserts Insert M2-M8
- Threaded Insert Press Kit with Soldering Iron and Accessories
- Threaded Insert Press Kit Pro with Soldering Iron and Accessories
Features:
- Brass material with high thermal conductivity allows for fast, even embedding in all common FDM thermoplastics
- Knurled outer surface anchors itself form-fit in solidifying plastic and reliably withstands pull-out and torque loads
- Standard size M2.5 × 4 × 4.6 mm (internal thread × height × outer diameter) – standard size for Raspberry Pi and SBC mounting projects
- Assembly with commercial soldering station or heat press - no need for thread cutting or post-processing
- Compatible with M2.5 screws (ISO metric), suitable for PLA, PETG, ABS, ASA, PC, and other thermoplastics
- 100 pieces per pack for series applications, prototyping, and repair work
Application Examples:
- Raspberry Pi cases and SBC mounts with M2.5 attachment points for permanent, robust screw connections
- 3D-printed electronic enclosures and project boxes with M2.5 screws for circuit boards and covers
- Voron and CoreXY printer projects with M2.5 attachment points
- Repair of plastic parts with damaged M2.5 threads through subsequent embedding
