Commonly used as locknuts, threading a thin nut against any other hex nut prevents loosening caused by vibration. You can also use them as jam nuts by threading two of these thin nuts against each other on a threaded rod to create a gripping point for turning the rod without damaging its threads. All are 18-8 stainless steel, which is nearly as strong as steel but won’t rust in outdoor, washdown, and other corrosive environments. ISO 4035 nuts are functionally the same as DIN 439B nuts (sometimes called DIN 439-2), but have slightly different width tolerances. These nuts have chamfered edges that make them less sharp than DIN 936 nuts. The information in this 3-D model is provided for reference only.
