Image Number 6 for United States Patent #5950297.
A support member attached to a support surface is rotated about a threaded stud to change the distance between an object on the support member and the support surface. The support member is fixed relative to the stud when the desired distance is attained, and a nut is fastened onto the stud, thereby trapping the object between the nut and the support member, and fixing the distance between the object and the support surface.
