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

Tighten these screws by turning them to the left; once fastened, they prevent counterclockwise-moving parts from loosening. Made from 18-8 stainless steel, these screws have 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.

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

More corrosion resistant than stainless steel screws, nickel alloy screws have excellent resistance to salt water and some acids.

Aluminum screws are one-third the weight of steel and have good corrosion resistance.

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.

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.

With a head one and a half times taller than a standard socket head, these screws are easier to install in deep counterbored holes and other hard-to-reach places.

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.

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

Stainless steel screws have excellent corrosion resistance in most environments. They have a split lock washer to create tension and resist loosening from vibration.

These general purpose flanged screws distribute pressure where the screw meets the surface, eliminating the need for a washer.

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

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

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.

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.

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

18-8 stainless steel screws have good chemical resistance and may be mildly magnetic. The flange distributes pressure across a wide surface, eliminating the need for a separate washer.

Made from alloy steel, these screws are nearly twice as strong as stainless steel button head screws. They have a flange that distributes pressure across a wide surface, eliminating the need for a separate washer.

These aluminum screws are lightweight and resist corrosion in wet environments. They have a flange that is wider and thicker than our other flanged screws, so they distribute pressure the best.

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

Tighten these screws by turning them to the left; once fastened, they prevent loosening from counterclockwise motion. Made from 18-8 stainless steel, these screws have good chemical resistance and may be mildly magnetic.

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

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

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

Stainless steel screws have excellent corrosion resistance in most environments.

A tamper-resistant hex drive (also known as pin-in hex drive) makes these screws difficult to remove without special tools.

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

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

These steel screws have corrosion-resistant finishes.

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.

With inch-sized threads the same diameter as the shoulder, these screws can handle heavy loads. They’re 18-8 stainless steel for good chemical resistance.

Screw these shoulders onto a stud.

These shoulder screws come with a traceable lot number and material test report.

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

Comparable to Grade 8 steel, these screws are the strongest precision shoulder screws we offer.

These 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.
