Below is the official press release from the management of PCM Precision Tooling SA.

Official press release November 5, 2024

Manufactured and available only from PCM Precision Tooling SA

Most of the toolholders currently on the market use either a hexagonal ER nut or a grooved ERM nut. These nuts are not interchangeable.

PCM Precision Tooling SA has succeeded in combining these two nuts, allowing you to simplify your tooling.

The ER-EM nut enables the lug wrench to be used on a tool originally designed for a hexagonal ER nut.

Conversely, the ERM-GS nut enables you to use an open-end wrench on a tool designed for an ERM grooved nut.

Opt for simplicity, efficiency and speed when changing your tools with just one wrench.
