These screws are chemical and oil resistant, nonconductive, and lightweight. Length is measured from under the head.

Nylon screws may expand when exposed to moisture. Glass-filled nylon screws are reinforced with fiberglass to be twice as strong as standard nylon screws.

Coarse threads are the industry standard; choose these screws if you don’t know the pitch or threads per inch. Fine threads are closely spaced to prevent loosening from vibration. They are not compatible with coarse threads.
