Flanged-Hex Easy-Adjust Push-Button Nuts

These nuts have a flange that distributes the load over a large area and reduces stress where the nut meets the material surface. Push the button to disengage the threads for quick adjustments on threaded rods. They can be tightened with a wrench once positioned by hand. A black-oxide finish provides corrosion resistance in dry environments.
