Set of brass threaded inserts M3 for 3D printing and plastics - 400 pcs,

Are you involved in 3D printing, plastic enclosure design or model making and need to create an extremely strong, durable and reusable metal thread in your plastic parts? The large 400-piece M3 (Heat Set Inserts) brass thread insert set is an indispensable tool for every creative DIYer, designer and professional working with FDM/SLA printers.

Forget about stripped threads directly in the plastic or the unreliable bonding of conventional nuts. These special knurled nuts are designed for heat sealing (e.g. with a soldering iron tip) or ultrasonic pressing. They ensure a perfect connection that reliably resists tension, torsion and vibration.

Key advantages that you will appreciate in every project:

Maximum tear-resistance thanks to knurling: the outer surface of the inserts has a cross/spiral knurling (Knurled) that locks firmly into the material when the surrounding plastic melts, preventing the nut from being rotated or pulled out.
Pure and premium brass: The inserts are made of high quality brass with excellent thermal conductivity. This ensures fast, smooth and even sealing without deforming the surrounding printed part.
Precise internal metric M3 thread. Ideal for 3D printer components, robotics or custom electronics.
With this kit, you can be sure that you won't run out of fasteners in the middle of a job. Suitable for series and prototype production.
