Made of high quality brass material, which provides the enhanced corrosion resistance, heat resistance, high hardness and durability.

With the design of the embossing process on the appearance, the nut insert forms certain friction and bites force after forming, so that it provides high tightening torque and can be fixed on the inside of the components, not easy to fall off when rotated.

The knurled nut can be installed into the 3D printer components by ultrasonic welding or heating and connected firmly.

Can be widely used in various applications, such as 3D printing injection molding, assembling plastic molding, and furniture manufacturing, to achieve tight fixation.
