M2.5x4x4 Brass Insert (25pcs)

M2.5x4x4 Brass Insert (25pcs)

M2.5x4x4 Brass Inserts provide a professional solution for creating strong threads in soft materials. These small, cylindrical components are made from high-quality brass. They are specifically designed for materials that are difficult to thread directly, such as plastics or wood. Each pack contains 25 precision-engineered pieces. Consequently, you can achieve secure and repeatable assemblies in all your custom projects. These inserts ensure your screws stay fastened without stripping the base material.

Key Features

These inserts feature a specialized knurled outer surface for maximum grip. This “brass knurling” design prevents the insert from turning or pulling out once installed. Furthermore, the high-quality brass construction offers excellent heat resistance and durability. You can easily install them using a soldering iron or during the injection molding process. Since they provide a metal-to-metal interface, they allow for frequent disassembly without wear. Therefore, your projects will maintain their structural integrity over many uses.

Specifications

Each insert has a precise internal diameter (ID) of 2.5mm. The outer diameter (OD) measures 3.9mm, providing a slim profile for tight spaces. With a total length of 4mm, they fit perfectly into standard 3D printed walls or thin enclosures. Because they are made of solid brass, they are naturally resistant to corrosion. This makes them ideal for both indoor and outdoor electronic housings. Thus, you get a reliable, long-lasting threading solution for every build.

Applications

These brass inserts are essential for high-quality 3D printing and prototyping. They enhance the durability of custom enclosures and mechanical parts significantly. In electronics, they provide a reliable method for mounting sensitive circuit boards. Moreover, they are perfect for creating robust connections in soft wood or molded plastics. Many engineers use them to ensure secure assembly in robotic frames. As a result, these inserts are a staple for any modern maker or manufacturer.
