Questions about this product

What are these three-hole coupling nuts for?
They join furniture and frame components with a locking, vibration-resistant connection. The flange spreads the clamping load and the three holes let you screw it down so it won't spin loose. Good for desks, racks, and workbench joints.
How do the three flange holes get fixed down?
The flange has a three-hole mounting pattern, with holes around 4 to 5.5mm. You run screws through them into the panel or frame to lock the nut in place. That stops rotation and keeps the joint tight under vibration.
Will these nuts hold up against rust and loosening?
They're carbon steel with zinc plating around 5 to 8 microns, which resists rust in normal indoor use. The flange and locking feature fight loosening from vibration. For outdoor or playground use, keep an eye on the coating over time.
