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.

Made from alloy steel, these screws are nearly twice as strong as stainless steel low-profile screws. With a head height one-third the size of a standard socket head, they fit in the tightest spaces.

These general purpose flanged screws distribute pressure where the screw meets the surface, eliminating the need for a washer.

These screws have good chemical resistance. A thread locker bonded to the threads prevents loosening from vibration.

A rubber O-ring under the head of these screws prevents leaks and seals out contaminants.

Fasten these screws inside a high-vacuum system without bringing in contaminants.

The nylon patch bonded to the threads of these socket head screws adds friction to keep vibration from loosening them, while their O-ring 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.

These metric alloy steel screws are nearly twice as strong as stainless steel button head screws.

As strong as alloy steel and about 40% lighter, these metric titanium screws are known for their high strength-to-weight ratio. They stand up to salt water, acids, and chemicals.

These metric 316 stainless steel screws resist corrosion from chemicals and salt water better than 18-8 stainless steel screws. They have a flange that distributes pressure across a wide surface, eliminating the need for a separate washer. Screws may be mildly magnetic.

With a flange comparable in size to a washer, these metric screws distribute pressure better than standard flanged screws. Made from 316 stainless steel, they have excellent resistance to chemicals and salt water. Screws may be mildly magnetic.

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.

To vent fluid and gas trapped under the screw, these metric screws are drilled through the shaft. Made from 18-8 stainless steel, they have good chemical resistance and may be mildly magnetic.

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.

More corrosion resistant than 18-8 stainless steel screws, these metric screws have excellent resistance to chemicals and salt water. They may be mildly magnetic.

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

Tighten these metric screws by turning them to the left; once fastened, they prevent loosening from counterclockwise motion.

These metric set screws have good chemical resistance.

These metric alloy steel set screws dig into hard surfaces for a secure hold. They have serrations on the cup edge that grip the material surface to resist loosening.

Made from alloy steel, these metric set screws have a thin edge that digs into hard surfaces for a secure hold. They have a nylon locking patch that grips threads to resist loosening.

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

Fine threads give you precise control.

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.

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.

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 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.

Turn these metric screws by hand using the hex head, or tighten them with a wrench for extra torque. With an extended tip that locks into a mating hole or slot—sometimes known as a dog point—they are often used to align and secure parts such as gears and pulley wheels.

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.

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

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

Use these screws in thin materials; they have a shorter threaded portion than our standard shoulder screws. They’re comparable in strength to Grade 8 steel.

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.
