The GDU MICRO WING NUT has been redesigned from the ground up to be ultra low profile so they can fit into areas never before thought of. They are extremely small with less chance of interference then any other wing nut on the market. They are small, strong and adjustable. The handle is spring loaded to allow you to rotate the handle out of the way, without loosening the screw. We included a hole large enough to fit a 3/16 wrench in the handle, just in case you need that extra torque in your life.
