These metric 18-8 stainless steel screws have good chemical resistance and may be mildly magnetic.

Brass screws are corrosion resistant in wet environments and electrically conductive.

More corrosion resistant than 18-8 stainless steel screws, these have excellent resistance to chemicals and salt water.

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

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

The green color identifies these as grounding screws. They have a flange that provides a wide flat surface for making solid electrical connections.

Also known as pancake head screws, these have a head that is about two-thirds the height of standard rounded head screws.

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

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.

Pair these screws with a barrel you already have or couple with a different barrel to create a custom fastener. Made from 18-8 stainless steel, they are chemical resistant.

These include a barrel and a screw with an extra-wide (truss) head. Made from 316 stainless steel, they have excellent chemical resistance and can be used in saltwater environments.

Use these barrels with a screw you already have or pair with a different type of screw to create a custom fastener. Made from 316 stainless steel, they have excellent chemical resistance and can be used in saltwater environments.

Shorter than shoulder screws for use in thin material.

Use these barrels with a screw you already have or pair with a different type of screw to create a custom fastener. They're zinc plated to resist corrosion in wet environments.

Install these screws with a wrench or a screwdriver. Made from stainless steel, they have good corrosion resistance. A flange under the head means a separate washer is not necessary.
