High Precision ER16M Clamping Nut for ER Tool Holder clamping nuts


ER NUT,Clamping Nut The commonly used types of tool holder nuts are: ER-A type: [ER11A, ER16A, ER20A], ER-M type: [ER8M, ER11M, ER16M], ER-UM type: [ER25UM, ER32UM, ER40UM, ER50UM], GER: [GER16, GER20, GER25, GER32], GSK, SK high-speed tool handle nuts. ER type for ER tool holder , SK for SK tool holder, GER for GER high-speed tool holder.The tool holder nuts are made of high quality chromium-molybdenum steel with hardness between HRC 46 and 52 degrees and accuracy within 0.005 mm. After hardening, the finish thread of the roughing truck is rust-proof on the surface, with exquisite appearance and durability. High Precision Clamping Nut The concentricity and precision of nuts are high, which meets the higher requirements of processed products. The machine tool processing accuracy and tool life are improved. High precision, good wear resistance, stable performance and reasonable price.

ER collet nut is a type of nut used in conjunction with an ER collet to secure a tool or workpiece in a machine tool such as a milling machine or lathe. The ER collet nut is threaded onto the collet and tightened to securely hold the tool or workpiece in place. It is typically made of steel and has a hexagonal shape to allow for easy tightening with a wrench or spanner. The ER collet nut is an essential component in the ER collet system, which is widely used in the metalworking industry for its precision and versatility.


clamping nut is a type of fastener that is used to secure or clamp two or more objects together. It typically consists of a threaded nut with a built-in mechanism that allows it to grip onto a surface or object, preventing it from moving or loosening.

Clamping nuts are commonly used in various appliCATEEions such as automotive, construction, and industrial settings. They are often used in conjunction with bolts or screws to provide a secure and tight connection.

The design of clamping nuts can vary, but they generally feature a serrated or textured surface on the inner side of the nut. This surface creates friction when tightened against the object, ensuring a strong grip and preventing any movement.

Some clamping nuts also have additional features such as a locking mechanism or a flange that provides extra stability and prevents rotation. These features are especially useful in appliCATEEions where vibrations or other external forces may cause the nut to loosen.

Overall, clamping nuts are a reliable and efficient fastening solution that provides a secure and tight connection between objects.
