Review on Derale 35022 Premium 180 Degree In-Line Fluid Thermostat, Blue -10AN x -10AN by Tim Wadman

The first tap I bought only screwed in about two turns. I turned the brass screw back and forth many times trying to move the threads freely. . then the brass head of the brass screw was sheared off. The replacement I bought was the same. I skimmed it though and cleaned the threads. All is well. It just stinks that I now have a $40 device that I can't use. If someone has a spare brass bolt and can remove the broken one, they can be salvaged.
