im not sure how to explain my problem but ill try.

my hi-hat stand is top of the line so im sure this problem can be fixed. if I play for about a half hour on the hi hat with it fairly loose the screw that holds the hats together loosens, and then the time it takes for the 2 hats to open is delayed when i take the foot of the pedal because the screw is loosening, and it doesn't have a counter screw on it. sorry thats the best way of explaining it. how can I fix this problem?
