These steel screws are zinc plated to resist corrosion in wet environments.

A rubber O-ring under the head creates a seal that withstands liquid and gas pressure.

These steel screws are available with corrosion resistant finishes. A rubber-bonded washer compresses to form a watertight seal. They save you time and effort by drilling their own holes and fastening in a single operation.

Made from 410 stainless steel, these screws are strong, wear resistant, and mildly chemical resistant.

18-8 stainless steel screws have good chemical resistance.

Cutting wings under the head allow plastic to expand and contract without cracking. A washer made from aluminum and rubber bonded to steel adds a watertight seal.
