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.

These metric screws are chemical and oil resistant, nonconductive, and lightweight. Exposure to moisture may cause them to expand.

These metric polycarbonate screws resist breaking in high-impact applications better than other plastic screws. All are chemical and oil resistant, nonconductive, and lightweight.

These screws are more reliable in high-stress, high-temperature environments than other plastic screws. They withstand water, steam, and temperatures up to 500° F.

Angled under the head, these metric screws fit in countersunk holes and sit flush with the surface of your part.

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

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.

Without a head to get in the way, these screws fit in tight spaces where standard shoulder screws cannot. Either thread them in a countersunk hole for a flush mount, or install them with the shoulder sticking out to use them as pins or dowels for aligning and locating components.

These slotted screws have a head height about one-third the head height of a standard shoulder screw. Use them in low-clearance applications such as inside machines.

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

Made of brass, these metric set screws are electrically conductive, nonmagnetic, and have mild corrosion resistance in wet areas. Their flat tip holds tightly on flat surfaces without damaging them, even when making frequent adjustments.

Good for humid, damp, and washdown areas, these metric 18-8 stainless steel set screws are more corrosion resistant than alloy steel set screws and nearly as strong. Their flat tip holds tightly on flat surfaces without damaging them, even when making frequent adjustments.

The green color identifies these as grounding screws. They have a flange that provides a wide flat surface for making solid electrical connections.

These screws have a hex head for a secure grip with a wrench.

Brass screws are corrosion resistant in wet environments and electrically conductive.

These steel screws are zinc plated to resist corrosion in wet environments.

These steel screws are zinc plated to resist corrosion in wet environments.

These steel screws are zinc plated to resist corrosion in wet environments.

18-8 stainless steel screws have good chemical resistance.

These slotted thumb screws are slim to fit in tight spaces.

Use these barrels with a screw you already have or pair with a different type of screw to create a custom fastener. Made from 18-8 stainless steel, they are chemical resistant.

Use these barrels with a screw you already have or pair with a different type of screw to create a custom fastener. Made from 316 stainless steel, they have excellent chemical resistance and can be used in saltwater environments.

Pair with a barrel you already have or couple with a different barrel to create a custom fastener. Made from 316 stainless steel, they have excellent chemical resistance and can be used in saltwater environments.

Use these barrels with a screw you already have or pair with a different type of screw to create a custom fastener. They're zinc plated to resist corrosion in wet environments.

Shorter than shoulder screws for use in thin material.

Stainless steel binding barrels and screws have excellent corrosion resistance in most environments.

Brass binding barrels and screws are corrosion resistant in wet environments and electrically conductive.

Plastic binding barrels and caps are chemical resistant, nonconductive, and lightweight.

Install these rounded head screws through a hole and thread on a retainer to keep secure—no special tools are required.

These rounded head nuts can be riveted into thin panels for a flush fit. They can be mounted without spaces between the panels. A quarter-turn locks and releases access panels, doors, and covers.

Press these rounded head nuts into the backside of a panel in applications where you have access to both sides of the panel. A quarter-turn locks and releases access panels, doors, and covers.

Bolts are beveled under the head for use in countersunk holes.

High-strength toggle anchors provide an extremely strong hold and stay in position when a bolt is removed.

Also known as Tapcons, these screws are often used to anchor parts to concrete, block, and brick. Assortments include a drill bit.

Slotted on both ends for installation with a screwdriver.
