Best Bonost in 2026

【Designed for Injection Molding】: With deep & clear knurls, the threaded inserts will add enough strength to screw connections when inserted into plastic components. The softened plastic will flow into the knurl pattern and then harden to form a firm bond with the insert.

【High-quality Material】: Made of premium brass material, our threaded insert for plastic has both aesthetics and high strength, which can be used for a long time. And the high thermal conductivity of brass thread inserts means faster heating and insertion into plastic parts.

【How to Use】: Female thread knurled insert nuts are suitable for mounting into tapered holes by heating or for molding during injection molding. You can use a soldering iron to heat it up and then pressing it into the hole. It is easy to control and at a low cost.

【Standard SAE Size】: There are 5 different UNC thread sizes of rivet nuts to meet your various needs, including #8-32 x 60pcs, #10-24 x 50pcs, 1/4''-20 x 40pcs, 3/8''-16 x 30pcs, 5/16''-18 x 20pcs. With clear label on the box, you can quickly find the right rivet nut you need.

【High-quality Material】: Made of premium zinc plated carbon steel, the riv nuts are corrosion resistant, sturdy, durable enough to meet different occasions. Wherever you need strong load-bearing threads in thin materials, Bonost rivet nutserts offer the ideal solution.

【Easy to Use】: These blind knurled body rivnuts can be easily installed from a single side of the work piece and provide a strong connection to the material. Ideal for assembly of box, or closed sections like castings, housings, panels, and tubes.

IMPROVING 3D PRINTING PROJECTS: Using 3D printers lets you create amazing projects. Innovative 3D printing tools like Virtjoule Heat-Set Insert Tips allow you to set threaded brass inserts into plastic to increase the strength of your part and also help you assemble and disassemble projects multiple times. These soldering tips, compatible with Hakko FX-888D and Weller SP40NKUS solder irons, make the job easy. With their square shoulder and slick finish, inserts won't stick on the tool and pull out.

OPTIMIZED SLIM PROFILE DESIGN: We originally created these long-shank tips to be compatible with the Hakko FX-888D iron. This design allows you to reach deeper into 3D-printer parts and tight corners without touching the side of your 3D-printed or injection molded part. The hot iron heats the tip and the brass insert, allowing it to melt into the piece. When set, the iron pulls out cleanly without sticking. A normal conical shape tip will often stick to the insert and pull it back out, ruining the project.

ONE SET, DIFFERENT TIP SIZES: Tip sizes include M2, M2.5, M3, M4, and M5. M2.5 is a popular hole size for Raspberry Pi circuit boards. M3 is a popular size for Arduino circuit boards. Our meticulously crafted soldering tips are smooth, and the edges are perfectly rounded, making a very slick slip between the tip and a brass insert.
