There was one complaint regarding UTS set screw movement. A patron of GT posted his UTS set screw backed off? He wanted to Loc-tite it down to prohibit future movement. I responded screw movement would virtually be impossible because the screw hole is undersized and the pressure on the screw is directly to the top of the screw. Loc-tite it if you wish but truthfully, I have built thousands of these and never had one move.
