About this item

uxcell knurled insert nuts are brass components crafted for 3D printing and plastic injection molding, ensuring strong, reliable joints in various assemblies. Made of high-hardness brass, they resist heat and corrosion, providing long-lasting performance.

The knurled outer surface creates friction and bite force, preventing slippage or fall-off after installation. These heat set inserts can be ultrasonic or heat-formed into plastic matrices, simplifying assembly processes. Their smooth surface and uniform size facilitate easy installation, making them ideal for precise, tight fixation in 3D printed parts or injection molded products.

Imported from the USA, these brass nuts are suitable for Indian manufacturing needs, supporting durable, high-torque applications. Delivered via ExpressBox, they arrive quickly, with all duties paid, ensuring hassle-free procurement for Indian makers and hobbyists.

Key Features

  • SIZE — Thread Dia: M5; Pitch: 0.8mm; Overall Size: 7mm x 8mm / 0.28" x 0.31"(OD*L)
  • MATERIAL — Made of brass material, high hardness and durable. Provides good mechanical properties with increased corrosion and heat resistance
  • FEATURE — The embedding nut has a guide so there is no need for a counterbore or countersink. Smooth surface, firm and uniform, easy to install.
  • ADVANTAGE — Due to the embossing process on the outer diameter of the insert, it forms certain friction and bites force with the brass insert after forming, which can be fixed on the inside so that it will not fall off easily. Has a certain torsion and tension.
  • APPLICATION — Can be installed by ultrasonic or heat into the plastic matrix, or formed during the injection, widely used in 3D printing injection molding to achieve tight fixation.

Why choose this product

Premium Brass Construction with Friction Bite

uxcell brass knurled insert nuts are crafted from high-hardness brass, ensuring excellent heat resistance and mechanical strength. The embossing process on the outer diameter creates a friction bite force, securing the nut firmly inside plastic parts, ideal for 3D printing and injection molding. This design outperforms standard threaded inserts by providing reliable, slip-resistant fixation, supporting high-torque applications with ease.

Ideal for Indian Makers & Hobbyists

These heat set brass nuts are perfect for Indian 3D printing and plastic assembly needs, supporting tight, durable joints in hobbyist and professional projects. They are easy to install via ultrasonic or heat, reducing assembly time and ensuring long-lasting performance. Suitable for various plastic matrices, they support reliable fixation in diverse environments, with quick delivery via ExpressBox and duties paid, making them accessible for Indian manufacturers and DIY enthusiasts.

How to use

  • Prepare the Plastic Surface — Ensure the plastic part is clean and free of debris. Use ultrasonic or heat insertion tools for proper embedding of the brass nut.
  • Insert the Nut — Heat the nut or plastic matrix to the recommended temperature. Press the nut into the hole until the embossing bites into the plastic, ensuring firm fixation.
  • Secure the Assembly — Allow cooling if heated. Insert the bolt or screw into the nut, tightening to achieve the desired tension. Confirm the nut holds firmly without slipping.
