The 3/8 tapped holes are cut after the screw is attached to them. I ordered two of these and both were taken down after the same period of use. The metal they are made of is very weak. The clips also don't reach the top of the mount, so I had to add filler between the top of the mount and the screws to attach thinner surfaces. One would think that they would at least come with screw terminals that reach the full length of the clip. I almost never write reviews. don't buy that. There are better clamps for the same price.
