Review: Good qaulity, nice selection, fair price. - I appreciate the nice selection of sizes and overall quality of these inserts. They work fine for my applications. Install easily using the Kadrick soldering iron tips. Since my application tends to be "one and done" use where the screw is seldom, if ever, removed, I can't comment on durability. I don't see any red flags that make me think these are less durable than any others that I have used. If I have one negative comment, it is that I would like the assortment to include more sizes of M4 and perhaps fewer M3. That said, this provides plenty of selection for prototyping parts and validating design and functionality. If I find that a different length insert in the prototyping stage, that is easy to resolve when I purchase larger quantities for production runs.
Review: Excellent budget set would recommend - Great set of screw inserts for those who are on a budget. All inserts are machined well and screws thread very nicely into the insert. Would recommend to purchase. Set also has a nice variety of inserts as well.

## Features

- 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.
