Tighten these screws by turning them to the left; once fastened, they prevent counterclockwise-moving parts from loosening.

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

Made of alloy steel, these low-profile screws are nearly twice as strong as their stainless steel counterparts. With half the height of a standard socket head, these low-profile screws fit in tight spaces.

More corrosion resistant than 18-8 stainless steel screws, these 316 stainless steel screws have excellent resistance to chemicals and salt water. Use these low-profile screws where space is limited.

Serrations under the head grip the material's surface for mild vibration resistance. The flange distributes pressure across the material's surface, eliminating the need for a washer.

With a tensile strength of 170,000 psi, these alloy steel screws are among the strongest we carry. They are stronger than Grade 8 steel screws and are nearly two and a half times stronger than stainless steel thread-locking screws. They have a thread locker to prevent loosening from vibration.

Seal out contaminants and prevent leaks—a rubber O-ring under the head prevents leaks and seals out contaminants.

316 stainless steel screws resist corrosion from chemicals and salt water better than 18-8 stainless steel screws. They may be mildly magnetic.

Designed for use in food, pharmaceutical, and other sanitary environments, these screws have an extra-wide truss head that distributes holding pressure to reduce the likelihood of crushing thin materials.

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

These metric brass screws are electrically conductive, nonmagnetic, and have good corrosion resistance.

These screws have metric thread sizes. They are 18-8 stainless steel for good chemical resistance.

For metric thread sizes with excellent resistance to chemicals and salt water, choose these 316 stainless steel shoulder screws.

These metric set screws have good chemical resistance.

These metric set screws have a tip that makes good contact on flat surfaces and allows you to make frequent adjustments with minimal surface damage.

Made from alloy steel, these metric set screws have a pointed tip that wedges into the contact surface for a secure hold on soft materials such as brass.
