Mintion M5 x 9.5mm x 7.1mm Threaded Insert Set – 50 pcs

M5 threaded inserts for maximum-strength 3D-printed joints

The Mintion M5 x 9.5mm x 7.1mm Threaded Insert Set is designed for 3D-printed assemblies that must withstand high mechanical loads and frequent maintenance. With 50 extra robust inserts in a single M5 size, this pack is ideal for machine frames, heavy brackets, tool holders and other demanding structural applications.

Dimensions focused on load capacity

Each insert features an M5 internal thread, 9.5 mm length and approximately 7.1 mm outer diameter. The large footprint inside the plastic spreads forces over a wider area, significantly improving resistance to pull-out, cracking and deformation under stress.

Secure anchoring in common 3D-printing plastics

The knurled brass body provides very high pull-out and torque resistance when heat-set into materials such as PLA, PETG and ABS. Compared to cutting M5 threads directly into plastic, these inserts offer a much more durable, serviceable and repeatable fastening solution.

50-piece set for heavy-duty projects

With 50 inserts included, this set supplies enough hardware for multiple large builds. It is particularly useful for printer and CNC upgrades, robotics, mechatronics, jigs and fixtures, and any project where strong M5 bolts interface with 3D-printed parts.

Compatible with heat-set tools and soldering irons

The inserts are intended for installation using heat-set insert tools, soldering irons and suitable adapter tips. Once heated and pressed into a properly sized hole, the knurling melts into the surrounding plastic and locks the insert firmly in place.

Typical use cases

Common applications include mounting stepper motors and actuators, securing metal brackets and plates, assembling machine frames and enclosures, attaching hinges and latches, and any high-load connection that benefits from reliable M5 threads in 3D-printed components.
