Ball Nut Lubrication

[ImagineRobots]

I noticed a threaded hole on all of my ball nuts from the CNC Fusion Deluxe kit for my X3. Does anyone know what this hole is for? See attached picture. I'm wondering if I can use this as a lubrication point for a one shot oiler.

thx

That hole is there specifically for a Zerk fitting, for lubrication.

Thanks for the Zerk info. It appears to be a 6mm thread. I think I'll buy some of these fittings and drill them out to fit the 1/8" hose in my one shot oiler system.
