About Socket Head Screws

Plastic Socket Head Screws
Fully Threaded
Partially Threaded
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. Polypropylene screws resist grease, acids, and alkalies better than nylon screws. Unlike nylon, they won't absorb moisture. PEEK screws are twice as strong as standard nylon screws and withstand temperatures up to 500° F. They resist more chemicals than polypropylene 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.
Screws that meet ASME B18.3 comply with specifications for dimensional standards.
