ER Sealed Nut

ER Nut is a type of clamping nut commonly used in precision machining applications. It is specifically designed to fit ER Collets, which hold cutting tools during machining operations. ER Nuts are typically made of high-quality steel, which provides durability and strength during use. ER Nuts feature a unique design that allows for the quick insertion and removal of cutting tools, making them ideal for use in CNC machines, milling machines, and other precision machining tools. They provide strong clamping force, ensuring the tool remains firmly in place during machining operations, reducing vibration and increasing machining efficiency. ER Nuts are available in various sizes, making them suitable for a wide range of machining applications.

Features

Nut is characterized by long process flow. Finish machining thread after overall quenching makes the critical dimensions more accurate and thread grade reaching grade 4H.
