Mintion M2 x 4mm x 3.6mm Threaded Insert Set – 70 pcs

M2 threaded inserts for precise 3D-printed assemblies

The Mintion M2 x 4mm x 3.6mm Threaded Insert Set is tailored for small, detailed 3D-printed parts that need reliable screw joints. With 70 pieces in a single, popular size, this pack is ideal as a standalone option for fine hardware or as a refill for your existing heat-set insert kits.

Optimised dimensions for compact parts

Each insert combines an M2 internal thread with a 4 mm length and approximately 3.6 mm outer diameter. This compact geometry works well in thin walls and tight spaces, making it a great choice for low-profile mounts, small covers and lightweight mechanical interfaces.

Secure grip in common 3D-printing materials

The inserts are made from knurled brass, providing excellent pull-out resistance and torque strength when heat-set into plastics. They are suitable for typical 3D-printing materials such as PLA, PETG and ABS, helping prevent cracked bosses and stripped plastic threads over time.

Convenient 70-piece refill pack

With 70 inserts included, this set is perfect for topping up your stock of M2 hardware without buying a full multi-size assortment. It is sold separately so you can match your inventory to the sizes you actually use most in your projects.

Compatible with heat-set tools and soldering irons

These inserts are designed to be installed with heat-set tools, soldering irons and compatible insert tips. Whether you use a dedicated heat-insert station or a handheld iron with the appropriate adapter, the M2 inserts integrate easily into a typical 3D-printing workflow.

Typical use cases

Common applications include mounting holes in small electronics housings, sensor brackets, camera and light fixtures, RC and robotics parts, as well as any compact assembly where repeatable disassembly and reliable M2 threads are required.
