Why Bolts Work (and why some don't)
.jpg)
Bolted joints are critical to the safe operation of equipment for a wide range of industries and applications, from packaging to electrical connections, valves and flanges, petrochemical and refining operations, to deep sea and offshore drilling equipment, structural systems, crossbows and even ski lifts. Over time, bolts stretch and lose their load due to a variety of reasons. Failure of the bolted joint in many cases can cause downtime for costly equipment repairs or be catastrophic— resulting in hazardous leaks, fires or fatal accidents.

In this white paper, we will discuss the three main important points to remember with bolting and why it is important to understand why factors such as embedment relaxation, differential thermal expansion, elastic interactions, vibration loosening, bolt creep and component yielding cause bolts to lose load and how to counteract these phenomena. Download the paper, Why Bolts Work (and why some don't), for a closer look at the science behind the elements of bolt stretch or elastic displacement, and how installing Solon Belleville Springs & Washers increases the elasticity to the fastening system and maintains bolt preload.
