Do not over-tighten the knob as this may damage or strip the threads in the mating assembly. Replace the knob if necessary.

These worked perfectly for the ones that had fallen off

Used these to provide leveling capabilities for some lab equipment which will not always be on a level surface. They were easy to install and work well.You might want to make sure the female section can be placed in the material it fits into. There may be some dense hardwoods which will not easily accept the prongs. You may have to make some indentations to more easily accept the prongs. Also, make sure the holes are drilled deep enough to accept the entire length of the screw.The only criticism I'd make is that after installation, a few of the screws were not real snug and tended to move slightly in the sleeve. More of a minor aggravation than a real problem. Maybe checking this first and slightly compressing the sleeve slightly would avoid the issue.
