These screws have good chemical resistance. A thread locker bonded to the threads prevents 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 nearly two and a half times stronger than stainless steel thread-locking screws. They have a thread locker to prevent loosening from vibration.

Stainless steel screws have excellent corrosion resistance in most environments. Wire these screws together for more vibration resistance than other types of socket head screws.

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.

Nonconductive and softer than brass, the nylon tip reduces vibration and eliminates damage from metal touching metal.

Twice as strong as low-strength steel screws, these screws are suitable for fastening most machinery and equipment.

Tighten these screws by turning them to the left; once fastened, they prevent counterclockwise-moving parts from loosening. For use in medium-strength fastening applications.

Choose these screws for their adherence to strict military standards for material and construction. Their high tensile strength means they can be used in demanding, high-stress applications.

About half as strong as medium-strength steel screws, these screws can be used for light duty fastening applications, such as securing access panels.

More corrosion resistant than 18-8 stainless steel screws, these 316 stainless steel screws have excellent resistance to chemicals and salt water.

Choose these screws for their excellent corrosion resistance—comparable to 316 stainless steel—and the strength of steel. Use them for high-strength fastening in chemical and marine applications.

Bronze screws are 30% stronger than brass screws and provide more corrosion resistance to salt water, gases, and sewage. They are nonmagnetic and electrically conductive.

Install these screws with a wrench or a screwdriver. Made from stainless steel, they have good corrosion resistance. A flange under the head means a separate washer is not necessary.

These screws are made from zinc-plated Grade 5 steel that’s stronger than stainless steel and provides corrosion resistance in wet environments. When wired together, they resist vibration better than any other hex head screw.

Made from 18-8 stainless steel, these screws have good chemical resistance. They have a thread locker to prevent loosening from vibration.

Made from alloy steel, these inch size set screws have a thin edge that digs into hard surfaces for a secure hold.

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

Made from 18-8 stainless steel, these set screws have good chemical resistance.

Use these steel set screws for light duty holding.

These set screws have good chemical resistance.

These alloy steel set screws have a thin edge that digs into hard surfaces for a secure hold. A nylon locking element grips threads 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.

Made from black-oxide alloy steel, these set screws resist corrosion in dry environments. They dig into hard surfaces for a secure hold and have serrations on the cup edge that grip the material surface to resist loosening.

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

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

These set screws have good chemical resistance.

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.

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

A nylon locking patch grips threads to resist loosening.

Made of alloy steel, these set screws are often used in U-shaped and V-shaped grooves and on other sloped or angled surfaces. The oval tip allows for frequent adjustments with minimal surface damage.

These set screws have a tip that is harder than nylon and silver to provide a secure hold on hard surfaces. The body is 18-8 stainless steel for good chemical resistance.

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.

Also known as full dog-point set screws, the tip is twice as long as the tip on other extended-tip set screws for greater engagement in deep mating holes.

Also known as half dog-point set screws, these set screws have a protruding tip that locks within a mating hole or slot to keep parts aligned.

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

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

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

Made from Grade 5 steel, these screws are suitable for fastening most machinery and equipment. Large flat sides make these screws easy to grip with a wrench and keep them from rotating in square holes.

These hangers are a popular choice for overhead applications.

About half the strength of medium-strength bolts, these Grade 2 bolts are for light duty fastening. Carriage bolts have a smooth, rounded head for a finished look. The square neck keeps these bolts from turning when tightening a nut.

These bolts have good chemical resistance. Carriage bolts have a smooth, rounded head for a finished look. The square neck keeps these bolts from turning when tightening a nut.

Twice as strong as low-strength steel bolts, these bolts are suitable for fastening most machinery and equipment. Carriage bolts have a smooth, rounded head for a finished look. The square neck keeps these bolts from turning when tightening a nut.

These metric alloy-steel screws are twice as strong as standard steel Torx flat head screws.
