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

Cleaned and double bagged in an ISO Class 5 (Class 100) clean room, these screws are ready to use on chambers and components in high-vacuum systems.

These screws are hardened to be 40% stronger than standard 316 stainless steel screws, yet they still have excellent corrosion resistance. Use them in chemical and marine applications.

Plastic screws are chemical and oil resistant, nonconductive, and lightweight.

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.

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.

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.

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.

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

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

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

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

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.

Made from 18-8 stainless steel, these metric set screws are chemical resistant. They have a nylon locking patch that grips threads to resist loosening.

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

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.

Fine threads give you precise control. A rolling ball allows for slight adjustments without loosening the screw.

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.

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.

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.

Made from 18-8 stainless steel, these metric button head screws have good chemical resistance and may be mildly magnetic. The tamper-resistant hex drive (also known as a pin-in hex drive) makes them difficult to remove without special tools.

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.

With a tamper-resistant hex drive (also known as a pin-in hex drive), these metric screws are difficult to remove without special tools.

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

The metric-sized threads on these screws are the same diameter as the shoulder. Comparable in strength to Class 12.9 steel.

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

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.

These metric 316 stainless steel shoulder screws are more corrosion resistant than 18-8 stainless steel shoulder screws. They also have excellent resistance to chemicals and salt water.

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

Set screws exert pressure at the tip to hold objects in place.

These assortments include button head screws.
