What are ER nuts used for?

ER nuts secure the collet within the tool holder. They ensure even clamping pressure, minimizing runout and tool slippage during operation.

What types of ER nuts are available?

PAC offers standard, mini, and bearing-style ER nuts. Mini nuts are compact for tight spaces, while bearing nuts reduce torque resistance for high-precision clamping.

Are ER wrenches size-specific?

Yes, each ER nut size (e.g., ER16, ER32) requires a matching wrench. Using the wrong wrench may result in poor grip or nut damage.

Is torque-controlled tightening necessary with ER wrenches?

For high-precision applications, a torque wrench with ER-specific adapters is recommended to prevent over-tightening and maintain consistency.

What holder types are supported by PAC tool locking devices?

PAC offers tool locking stations for CAT, BT, HSK, and other tapers—both horizontal and vertical mount options are available.

Why is a tool locking device important in a workshop?

It ensures safe, stable, and accurate torque application, especially in heavy-duty or high-precision tool setups.
