Nylon fasteners are used primarily in applications where mild corrosion resistance and electrical non-conductivity are the major requirements. They will not rust or corrode when exposed to chemicals (except mineral acids). Fasteners possess a certain amount of "give," conforming to irregular surfaces as well as dampening vibrations and preventing loosening due to vibration. Frequently used in electrical work to ensure good connections. Light in weight, inexpensive, a good alternative to expensive metal parts. Intended for temperatures from 0° to 300°F. Nylon fasteners will absorb moisture from the environment over time; this affects their strength and dimensional properties, and they should be replaced when wear becomes apparent.
