After firing 6 357 loads my yoke screw come loose and when i tighten it it looks like it is little binds with crane not too much but very little it is binding when swinging crane upward and downward i dont know if its is factory fitted on that position or it has another issue
Should i use nail polish as a loctite ?
If It's the type that resembles, the other plate screws, It usually can be turned untill It stops. Without turning It any tighter than plate screws.
It they are clean and dry, they usually don't come loose unless they were loose at the start.
Remember they have fine thread, and any deliberate force will strip threads easily, causing a much worse problem. Whatever you try to stick on It will probably work, just keep in mind, It's super easy to strip, don't force them tight.
