The standard for high-strength fastening.

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

Use these general purpose 18-8 stainless steel screws for a variety of fastening applications. They have good chemical resistance.

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

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.

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

Bronze screws are about 40% stronger than brass screws and provide more corrosion resistance to salt water, gases, and sewage. They are nonmagnetic and electrically conductive.

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.

More corrosion resistant than 18-8 stainless steel screws, these 316 stainless steel screws have excellent resistance to chemicals and salt water. Their ultra-low-profile lets them fit in the tightest spaces.

For use where sideways forces are a concern, these screws have a precisely measured unthreaded portion (grip) for a strong hold. Their flanged head distributes pressure where the screw meets the surface, so you don't need a washer.

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.

Seal out contaminants and prevent leaks—a rubber O-ring under the head prevents leaks and seals out 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.

The nonmarring brass tip is electrically conductive and harder than nylon, but soft enough to conform to most surfaces and reduce damage from metal-on-metal contact.

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

Comparable in strength to Grade 8 steel. These screws have inch thread sizes.

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.

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 screws have inch thread sizes.

These shoulder screws are chemical resistant, nonconductive, and lightweight.

These have a head height about one-third the head height of a standard shoulder screw.

These shoulder screws have good chemical resistance.

Screw these shoulders onto a stud.

Made of 416 stainless steel, these shoulder screws are almost twice as strong as 18-8 stainless steel and have the same corrosion resistance.

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

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.

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 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 nylon set screws are chemical resistant, lightweight, and nonconductive. 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.

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.

Stainless steel set screws have excellent corrosion resistance in most environments.

A nylon locking patch grips threads to resist loosening.

These 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.

Stainless steel set screws have excellent corrosion resistance in most environments.
