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.
