Brass Hot Melt Threaded Inserts Assortment Set - M2 M2.5 M3 M4 M5 (220 Pieces)

Add durable, reusable metric threads to your 3D printed parts with this 220-piece Brass Hot Melt Threaded Insert Set. Made from high-quality solid brass, these heat-set inserts feature a knurled outer surface that provides high pull-out and torque resistance when melted into thermoplastics like PLA, PETG, ABS, ASA, and Nylon using a standard soldering iron. Neatly organized in a clear plastic compartment box, this compact set covers essential M2, M2.5, M3, M4, and M5 sizes for 3D printing post-processing, mechanical assemblies, and DIY electronics.

KEY FEATURES:

• Premium Solid Brass Construction: High thermal conductivity, excellent corrosion resistance, and durable long-term performance.

• Knurled Opposed Design: Diagonal knurling creates a strong mechanical bond within melted plastic to resist twisting and pulling forces.
