Collet clamping nuts, also known as ER nuts, come in different sizes to match the corresponding collet size. ER nuts are available in a variety of sizes. These dimensions refer to the maximum collet capacity that the nut can accommodate. In addition to the ER nut size, the quality of the ER collet nut itself is also important. Nuts should be made of a high-quality material such as steel to ensure durability and longevity.
