Heat Set Threaded Inserts, 25 Pcs 1/4"-20 x 8mm L x 8mm OD Pure Brass Metric Knurled Nuts Female Threaded Inserts Embedment Nut for 3D Printing Components Plastic Materials

What is this?

These pure brass thread inserts are common fastening components for thermoplastics(like PLA, PETG, ABS, PP, and others). They are usually parts in 3D printed prototypes, reinforcing plastic joints or adding thread inserts to plastic parts to add sufficient strength to the threaded connection. Widely used in 3D printing, injection plastic parts, automotive plastic housings, laptop housings, electronic products, circuit board fixings, etc.

Is there any advantages of the product?

Made of good pure brass material, these thread insert nuts have excellent thermal conductivity, corrosion resistance, and durability. They are resistant to breakage and deformation, strong and durable, will not rust, and can easily endure the harsh heat generated during plastic thermal shaping processes.

With fine processing technology, the external reverse spiral knurling design significantly enhances the torque resistance and tensile strength, ensuring a firm and stable connection to prevent falling off. The Female thread is deep and clear, the force is evenly distributed, and the threaded connection is more secure.

The embedding nut has a guide device and does not require a counterbore or countersink. It can be installed into the 3D printer component by heating or ultrasonic means, or formed during the injection molding process.

How to use it?

You can use a common soldering iron to heat it up and then easily press it into the hole. Allow it to cool down and solidify within the plastic material.

What should I notice?
