For optimal performance, use a heat insert tool to install the knurled brass insert nuts. This method allows the insert to be embedded more easily and securely into the material. The heat softens the surrounding material, allowing the knurled surface to grip more effectively. This technique is especially useful for plastic and softer materials, ensuring a strong and durable connection.
