Product Details
Product Name: Yongjing UM Type / Type A ER Cap Nut (ER32 Nut)
Product Grade: Grade A
Performance Grade: Grade 4.8
Material: Carbon Steel
Surface Treatment: Black Oxide Coated
Product Type: UM Type / Type A ER Lock Nut
Product Description
Product Overview
This product is a UM type (also known as Type A) ER32 specification collet lock nut (commonly known as ER cap nut), manufactured from carbon steel material with a performance grade of 4.8 and black oxide coating on the surface. As a key component of the standard ER collet system, this nut is used to lock the ER32 collet onto the corresponding tool holder or spindle adapter. It generates radial contraction of the collet through axial pressure, thereby reliably clamping tools (such as drills, end mills, taps) with a shank size of 32mm or less.
Core Advantages
-
Precise Clamping and Locking: Standard ER32 interface, precision-matched with ER32 collets and tool holders, ensuring clamping accuracy and runout accuracy.
-
Strong Versatility: UM (A) type is the most common form of ER nut, compatible with most standard ER32 tool holders and collets.
-
Rust and Wear Resistance: The black oxide surface provides basic rust resistance and reduces wear with the tool holder threads.
-
Economical and Practical: Carbon steel material meets general processing needs and has excellent cost performance.

Warm Tips
-
Before installation, please ensure that the nut, collet and tool holder taper hole are clean and free of foreign objects to ensure clamping accuracy.
-
Please use the supporting dedicated wrench when locking and apply uniform torque to avoid one-sided force.
-
It is recommended to regularly check whether the nut threads and end faces are worn or damaged, and replace them in time to ensure processing safety and accuracy.
-
Under high-speed or heavy cutting conditions, please confirm whether its performance grade meets the requirements; if necessary, select products with higher strength materials.
