About this item
- 【High Quality Brass, Corrosion Resistant】This thread insert is made of high quality brass. It is made using hot melt technology and has excellent properties such as high temperature resistance, waterproof and shock resistance. It is also robust and durable. Even if it is in a humid environment for a long time, it does not react chemically with substances in the air, resulting in rust or looseness.
- 【Application】: Insert the threaded nut into the hole and heat the nut with a soldering iron. After heating, the threaded insert is pressed into the part. Then the screws are mounted with the cooled nuts. Using ultrasonic waves or a soldering iron, nuts can be easily inserted into plastic parts.
- Perfect twill thread: the surface of the 3D printed brass press nut has twill thread, and the high-precision internal threads ensure that the nut fits tightly to the installation object and creates a certain friction and bite force that can be fixed to the installation object. Prevent falls.
- Smooth polished and good thermal conductivity: each 3D printed nut with thread insert in this product has been carefully polished and has no burrs on the surface. Copper has good thermal conductivity, which not only allows the copper nut to heat up quickly and accelerate work efficiency, but the copper nut also conducts heat to the plastic part, making the plastic hole softer, so that the thread can be printed in 3D easier to insert into the hole.
- 【Application】: Nuts are mainly used in threaded joints of steel structures, mechanical equipment, electronic products, injection molding, circuit board assembly, electronic products and most plastic fasteners (e.g. plastic fixings). They are also suitable for PLA, PETG, ABS, PPS, PP, anything with holes can be injected
- Thread insert: press nuts, melting thread, melting thread, 3D printer accessories, thread sleeve

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
