Choose these screws for their adherence to strict military standards for material and construction. Screws are 18-8 stainless steel for good chemical resistance.

More corrosion resistant than 18-8 stainless steel screws, these 316 stainless steel screws have excellent resistance to chemicals and salt water.

With the strength of steel and the corrosion resistance of 18-8 stainless steel, these 17-4 PH stainless steel screws are suitable for high-strength fastening in corrosive environments.

These Grade B8 screws are made from 18-8 stainless steel and have good chemical resistance. Also known as pressure bolts, they meet the high-pressure and high-temperature regulations of ASTM A193 and are used to secure pressure tanks, valves, and flanges.

Made from 18-8 stainless steel, these screws have good chemical resistance. A flange under the head distributes pressure over the surface, eliminating the need for a washer.

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.

More corrosion resistant than 18-8 stainless steel screws, these 316 stainless steel screws have excellent resistance to chemicals and salt water. A serrated flange provides mild vibration resistance.

Made from 18-8 stainless steel, these screws have the best chemical and corrosion resistance of our wire-lockable screws. Wire these screws together for more vibration resistance than other types of hex head screws.

A freely rotating but permanently attached washer distributes pressure over a wider area than a flange, preventing damage to your material's surface.

Drilled through the head and shaft, these screws vent fluid and gases trapped below the screw, making them good for vacuum applications.

18-8 stainless steel screws have good chemical resistance.

These 316 stainless steel screws have excellent resistance to chemicals and salt water.

Tighten these thumb screws by hand or with a hex key for more torque.
