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.
Plastic screws are chemical and oil resistant, nonconductive, and lightweight.
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.
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. Use these low-profile screws where space is limited.
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.
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.
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.
These screws have good chemical resistance. A thread locker bonded to the threads prevents loosening from vibration.
These general purpose flanged screws distribute pressure where the screw meets the surface, eliminating the need for a washer.
Serrations under the head grip the material's surface for mild vibration resistance. The flange distributes pressure across the material's surface, eliminating the need for a washer.
A rubber O-ring under the head of these screws prevents leaks and seals out contaminants.
Drilled through the head and shaft, these screws vent fluid and gases trapped below the screw, making them good for vacuum applications.
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.
316 stainless steel screws resist corrosion from chemicals and salt water better than 18-8 stainless steel screws. They may be mildly magnetic.
These metric alloy steel screws are nearly twice as strong as stainless steel button head screws.
18-8 stainless steel screws have good chemical resistance and may be mildly magnetic. A Torx drive has more points of contact than other drives, allowing you to tighten the screw without damaging the recess.
These metric alloy steel 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.
Made from 18-8 stainless steel, these metric screws have good chemical resistance and may be mildly magnetic. They have a flange that distributes pressure across a wide surface, eliminating the need for a separate washer.
Made from 18-8 stainless steel, these metric button head screws have good chemical resistance and may be mildly magnetic. The tamper-resistant Torx drive (also known as a pin-in Torx drive) makes them difficult to remove without special tools.
Made from 18-8 stainless steel, these metric button head screws have good chemical resistance and may be mildly magnetic. The tamper-resistant hex drive (also known as a pin-in hex drive) makes them difficult to remove without special tools.
These metric 18-8 stainless steel screws have good chemical resistance and may be mildly magnetic.
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 brass screws are electrically conductive, nonmagnetic, and have good corrosion resistance.
