Question: What type of retaining nuts are used with the Power Module?

Answer: Prior to mid 2004, we used a lightly plated metric nut. These worked but occasionally rusted and required thread locker to ensure they stayed tight.

Since mid 2004 we have used a plated (chrome look) metric self locking hex nut like you would find on high end machinery. These look better, work better and do not require thread locker.
