Sorry and thank you for offering gresh! I overlooked your first post ,iPhone FTW!
They didn't have 1/4-20 nylon thumb screws nor wing nuts I got hex thread at 1" long. It will get the job done for my lifereef overflow box I originally had it only 55 gal installled in a position that required the screw to be shorter. Now I can install the box on my 100 gal the correct way requiring the longer screw to make it thread properly.
