Choose these screws for their adherence to strict military standards for material and construction. Screws are 18-8 stainless steel for good chemical resistance.

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.

Brass screws are electrically conductive, nonmagnetic, and have good corrosion resistance.

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.

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.

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 more than twice as strong as stainless steel wire-lockable screws. These resist vibration better than any other socket head screw.

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

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

These pan head screws are zinc plated for corrosion resistance in wet environments.

Nylon pan head screws are chemical and oil resistant, nonconductive, and lightweight. Exposure to moisture may cause them to expand.

Brass pan head screws are corrosion resistant in wet environments, nonmagnetic, and electrically conductive.

More corrosion resistant than 18-8 stainless steel screws, these screws have excellent resistance to chemicals and salt water. The extra-wide truss head distributes holding pressure to reduce the likelihood of crushing thin material. Screws may be mildly magnetic.

A zinc plating provides mild corrosion resistance.

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

Stainless steel screws have excellent corrosion resistance in most environments.

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

Made from alloy steel, these screws are three times stronger than standard steel button head Torx screws. A Torx-Plus drive has more points of contact than other drives, allowing you to tighten the screw without damaging the recess.

These screws have a Torx or Torx-Plus drive for more points of contact than other drives, allowing you to tighten the screw without damaging the recess.

These screws have a tall, domed head that provides a finished appearance. They're zinc plated to resist corrosion in wet environments.

Made from alloy steel, these screws are nearly twice as strong as stainless steel button head screws.

Wire these screws together through the hole in the head for better vibration resistance than any other rounded head screw.

A nylon patch bonded to the threads adds friction to resist loosening from vibration.

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

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

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

These steel screws have a zinc plating for mild corrosion resistance.

These screws have a decorative, domed head that sits above the surface when installed.

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

Stainless steel screws have excellent corrosion resistance in most environments.

These screws are drilled through the shaft to vent fluids and gases trapped under the screw.

These steel screws cut threads in drilled holes as they’re turned, so they require less driving torque and cause less stress on your material than thread forming screws.

The triangular shank presses tightly as it forms threads, so screws resist loosening in soft metals such as brass, aluminum, and copper.

Made from 18-8 stainless steel, these inch-sized shoulder screws have good chemical resistance.

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

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.

Choose these set screws for their adherence to strict military standards for material and construction.

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

Made from 18-8 stainless steel, these 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 chemical-resistant 18-8 stainless steel screws have an extra-soft nylon tip, which minimizes the damage that can occur from metal-on-metal contact. Use them on soft surfaces such as aluminum.

With a tip that's harder than nylon and silver, these alloy steel set screws provide a secure hold on hard surfaces. The body has a black-oxide finish to resist corrosion in dry environments.

These set screws have a softer tip than brass-tip set screws to minimize surface damage. Use them on hard surfaces.

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

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

18-8 stainless steel threaded rods have good chemical resistance.

One-third the weight of steel, aluminum threaded rods resist corrosion in wet environments.

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

Change inch threads to metric with these adapters, or swap metric threads for inch. An external hex lets you tighten or loosen them with a wrench.

One side inch, one side metric, and a hex in the middle—these handy fasteners connect two female-threaded parts, such as coupling nuts, adapting from inch threads to metric. Tighten with a standard wrench.
