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.

Often used to fasten parts in engines and turbines, these are our strongest stainless steel screws. They are comparable in strength to alloy steel with the corrosion resistance of 18-8 stainless steel.

Our most corrosion-resistant metal screws, titanium screws withstand salt water, acids, and chemicals. They have a high strength-to-weight ratio and are about 40% lighter than steel screws.

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.

Nearly as strong as steel, these stainless steel screws won’t rust in outdoor, washdown, and other corrosive environments. With half the height of a standard socket head, these low-profile screws fit in tight spaces.

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

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 silicone O-ring under the head creates a water-, oil-, and chemical-resistant seal.

Closely spaced threads on these screws fit in holes with a fine pitch. They're not compatible with standard metric threads.

To vent fluids and gases trapped under the screw, these metric screws are drilled through the shaft.

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

Made from 18-8 stainless steel, these metric screws have good chemical resistance and may be mildly magnetic. They have a flange that distributes pressure across a wide surface, eliminating the need for a separate washer.

These metric 18-8 stainless steel screws have good chemical resistance and may be mildly magnetic. The flange is wider and thicker than our other flanged screws, so they distribute pressure the best.

Made from aluminum, these metric screws are lightweight and resist corrosion in wet environments. The flange is wider and thicker than our other flanged screws, so they distribute pressure the best.

Turn these metric screws to the left to tighten; once fastened, they prevent loosening from counterclockwise motion. Made from 18-8 stainless steel, they have good chemical resistance and may be mildly magnetic.

Nearly twice as strong as stainless steel button head screws, these metric screws are made from alloy steel. Their tamper-resistant Torx drive (also known as a pin-in Torx drive) makes them difficult to remove without special tools.

These metric 316 stainless steel set screws have excellent chemical resistance and can be used in saltwater environments.

Made from alloy steel, these metric fine-thread set screws have a thin edge that digs into hard surfaces for a secure hold.

These metric set screws are vented to allow fluid and gas to pass through.

These metric 18-8 stainless steel set screws are chemical resistant. They have serrations on the cup edge that grip the material surface to resist loosening.

These metric 18-8 stainless steel set screws are chemical resistant. The tip makes good contact on flat surfaces and allows you to make frequent adjustments with minimal surface damage.

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.

Available in metric sizes, these alloy steel set screws have an extra-soft nylon tip that minimizes the damage that can occur from metal-on-metal contact. Use them on soft surfaces such as aluminum.

These metric set screws have a brass tip, which is harder than nylon and silver, for a secure hold on hard surfaces. The body has a black-oxide finish to resist corrosion in dry environments.

These metric 18-8 stainless steel set screws are chemical resistant. A pointed tip wedges into the contact surface for a secure hold on soft materials such as brass.

Also known as dog-point set screws, these metric set screws have a protruding tip that locks within a mating hole or slot to keep parts aligned. Made of 18-8 stainless steel, they have good chemical resistance.

These metric set screws have a protruding tip that locks within a mating hole or slot to keep parts aligned. They're also known as half dog-point set screws.

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 screws have a head height that's about two-thirds the head height of a standard shoulder screw. Use them in low-clearance applications such as inside machines.

Offered in metric sizes, these brass shoulder screws are electrically conductive, nonmagnetic, and have good corrosion resistance.

Install and remove these metric shoulder screws by hand or with a hex key.
