Keep pipe flange connections sealed to prevent damage and leaks. These springs compensate for flange bolt heads and nuts as they shift from vibration and expand or contract from temperature changes. Unlike spring lock washers, they return to their original height again and again when decompressed. Also known as Belleville disc springs.

To increase working load or deflection, stack multiple springs. A nested stack increases working load; an inverted stack increases deflection. In a nested and inverted stack, both load and deflection increase. Multiply the original working load or deflection (depending on your configuration) by the number of springs to find your new total.

Designed for use with bearing nuts, these lock washers have a conical shape that presses like a spring against bearings, bushings, gears, and pulleys to hold them in place on your threaded shaft or spindle. They also have an inner tab that sits in the shaft or spindle’s keyway to prevent the nut from loosening.
