Easy to install, no special tools required, just follow these simple steps. > place the well nut in a pre-drilled hole with the flange part on top of the mounted material and the straight body on the blind side. > As you tighten the component the body of the well nut compresses and bulges 360 degrees. > the well nut has now created a lip on the blind side of the material and firmly interlocked itself onto the material. > Job well done :)
