Review on 🔧 SMALLRIG Articulating Rosette Arm: 7 Inches Long, Cold Shoe Mount, 1/4"-20 Screw Adapter - 1497 by Monica Nixon

If you overtighten the nut, the aluminum nut will break. If you have a heavy load, e.g. a monitor, you need to tighten it to keep it from moving. The nut can be easily replaced with a wing nut and washer if it breaks. I didn't get a response from their warranty department so I'm not overly impressed.
