The M4 X 12mm Brass threaded inserts are 4mm in internal diameter and 12mm in length. They are small, cylindrical components made from high-quality brass, designed to provide strong, durable threads in materials that are otherwise difficult to thread directly, such as plastics, wood, or soft metals. These inserts feature internal threading, allowing screws or bolts to be securely fastened.

Uses:

• Electronics: Provide reliable threads for mounting circuit boards and electronic components.
• 3D Printing: Brass threaded inserts in 3D printing enhance durability, heat resistance, and secure assembly, ensuring robust connections for prototypes, custom enclosures, and mechanical parts. Essential for reliable, long-lasting prints.

Brass threaded inserts are essential for enhancing the strength and longevity of threaded connections in various applications, ensuring reliable and repeatable assembly. They are also known as brass knurling inserts.
