Technical Tips from Mark W. Persons
Stainless Steel Hardware Problems

October 8, 2008:  If you run into stainless steel bolts and nuts that will not come apart, then you are not alone.  This a common problem.  Stainless steel is great for inhibiting corrosion, but it is also well known for threads that "gall" causing bolts and nuts to stick together so well that they will not come apart. 

That is where you might need this tool.  Enter the electric hand grinder.  It is quicker and easier that a hacksaw.  This one is a Makita 9523NBH, which has a four-inch abrasive grinding wheel that turns at 1000 rpm.         

Behind those sparks is the grinder in action cutting a 5/16" stainless steel bolt and nut on the back of a 3" coaxial patch panel at an FM transmitter site.  The work takes less than 10 minutes and is fun to boot!       

The stories go on and on.  Stop in again sometime.  I'll leave the soldering iron on for you.
