About this item

  • Suitable for 3D printing: Brass threaded inserts, which can be embedded into plastic materials using the heat from a soldering iron or ultrasound, are the optimal solution for adding threads in 3D printing.
  • Common specifications: We have created this set of inserts using a large quantity of M3 inserts combined with M4 and M5 inserts, based on the most commonly used specifications by 3D printing enthusiasts. The heights range from 3mm to 12mm. We hope you will like it.
  • Secure fixation: Our brass threaded inserts are made of high-quality brass and undergo precision processing, ensuring excellent heat conduction and corrosion resistance. Through testing, we have found that compared to straight-threaded inserts, the knurled threaded inserts provide stronger gripping strength and can withstand high levels of tensile force.
  • Clear labeling: Each specification has its own independent compartment in the plastic box, and we have attached labels with detailed annotations for key data, making it convenient to use.
  • Brand guarantee: Kadrick specializes in the production and development of fasteners. Our products have undergone rigorous testing, so you can use them with confidence. Additionally, we provide a 24-month after-sales warranty service. If you have any questions, please feel free to contact us.

These are heat inserts and they do what they say on the tin. If you need them, get them.

Love these. Can’t say I’ve used other brands or have extensive experience with such a product. The packaging/container keeps everything well organized. One end is nice and smooth for starting while there’s a little lip on the back side for making it cleanly set in the target material. Beats the heck out of just using standard nuts.

First time I’ve used these type of inserts and wow they’re sweet! Tapered on the end, slides right in and hold tight. I’ll definitely be making these a part of my building process from now on.

I've already used these in multiple projects to great success. However, they came reeking of machining oil, which I washed off with dish soap in case it would affect the security of the melted interface, especially on the very small pieces.

Los tornillos encajan perfectamente. Encargué esto para mis impresiones 3D y ahora son mucho más profesionales.

Great set of inserts that I'll be used with some 3d printer parts.
