ER32 clamping nut of UM type is a type of clamping nut used in ER32 collet chucks. ER32 collet chucks are used in machining operations to hold and secure cutting tools or workpieces.

The ER32 clamping nut of UM type is designed to securely tighten and hold the collet in place within the collet chuck. It features a threaded design that allows it to be easily tightened or loosened using a wrench or spanner.

The UM type clamping nut is known for its high clamping force and precise gripping capabilities. It is commonly used in various machining operations such as milling, drilling, and turning.

The ER32 clamping nut of UM type is made from high-quality materials such as steel or stainless steel to ensure durability and long-lasting performance. It is also available in different sizes to accommodate different collet sizes.


Clamping nuts are a type of fastener that is used to secure objects together by creating a tight and secure connection. They are typically used in appliCATEEions where vibration or movement may cause traditional nuts to loosen over time.

Clamping nuts are designed with a serrated or toothed surface on the inside, which helps to grip the mating surface and prevent loosening. When the nut is tightened, the teeth dig into the material, creating a strong and secure hold.

These nuts are commonly used in automotive, machinery, and industrial appliCATEEions where stability and reliability are crucial. They are available in various sizes and materials, such as steel, stainless steel, and brass, to suit different requirements.
