M6 x 8 x 8 1 /4-20 x 12.7 x 8 (dimensions in millimeters) in 300 pieces. They are stored in different compartments of a plastic box and are labeled to avoid confusion.
• 【Brass material】: The nut is made of brass material, high hardness and durable. With good mechanical properties, corrosion resistance and heat resistance is stronger. Brass threaded inserts have high thermal conductivity, so heating and inserting plastic parts is faster.
• 【Excellent workmanship】: The internal thread knurled nut has a smooth and burr-free appearance, deep and clear threads, even threads and not easy to slip, will not damage other parts.
• 【Stable Fixing】: The knurled pattern on the outside of the nut is not only beautiful, but also increases the friction between the nut and the hand, making it easier to rotate, and the rounded design of the head can be well positioned; it is not easy to be skewed and ensures stable insertion.
• 【Wide Application】: They can be installed into the plastic substrate by ultrasonic or heating, or molded during injection molding, widely used in 3D printing injection molding, computer products, electronic products, circuit board fixing and so on, to achieve tight fixing.

300 Pieces Brass Knurled Threaded Nut Inserts, Threaded Inserts Embedded Nut Kits for Plastic Parts for 3D Printer Components. Features: 1. Threaded nuts are made of brass for high hardness and durability. It has good mechanical properties with higher corrosion and heat resistance. 2. The knurling pattern on the outside of the threaded nut is not only beautiful, but also increases the friction between the nut and the hand, making it easier to rotate, and the rounded design of the head allows for good positioning; Threaded nuts are not easy to twist and are easy to install. 3. These brass nuts usually use processes such as hot fusion, hot pressing, ultrasonic welding and injection molding to make the product bite firmly into the plastic parts, serving as connection, locking and fastening. 4. Threaded nuts are widely used in 3D printing injection molding, computer products, electronic products, PCB fixtures, etc. to achieve fixation.
