This is a replacement clamp for the Logitech G920 steering wheel. it uses a 14 mil screw (m14). 

Since the clamp itself is printed sideways for strength, the thread gets deformed which makes screwing the m14 screw in place very difficult. I suggest using an m14 tap drill to ensure a good fit. If you do not have this tool, cutting 4 horizontal lines in a m14 screw also does the trick. 

If this model helps you out, please leave a comment! Thank you!
