The two parts are combined by their threads' friction, a slight stretching of the bolt and compression of the parts to be held together. In common use, a nut-and bolt joint holds together because the bolt is under a constant tensile stress called the preload. The 304 stainless steel provide perfect strength and good corrosion resistance in bad environments like high temperature, cold weather and high humidity areas without the need for time consuming and costly maintenance.
