Here is a lot of 2 heavy duty steel screw hold down clamps. These are designed to thread into a base plate and the head can rotate 90 degrees as shown using the cam slot as shown. These are very heavy duty. They held 2000 lb plates in place on a sputtering chamber. The clamp threads are about 3/4″ in diameter. Each clamp weighs nearly 10 lbs.
