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.

These Grade B8 screws are made from 18-8 stainless steel and have good chemical resistance. Also known as pressure bolts, they meet the high-pressure and high-temperature regulations of ASTM A193 and are used to secure pressure tanks, valves, and flanges.

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.

Made from 18-8 stainless steel, these screws have good chemical resistance. Their flange is serrated to help prevent loosening from vibration.

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

An O-ring under the head prevents leaks and seals out contaminants.

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

Cleaned and double bagged in an ISO Class 5 (Fed. Std. Class 100) clean room, these screws are ready to use on chambers and components in high-vacuum systems.

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.

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

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.

These 18-8 stainless steel screws have a hardened steel drill point to penetrate steel and are coated to increase corrosion resistance.

18-8 stainless steel screws have good chemical resistance.

Also known as pin-in-hex, install and remove these screws with a tamper-resistant hex driver.

18-8 stainless steel screws have good chemical resistance.

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

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

With a tamper-resistant hex drive (also known as a pin-in hex drive), these metric screws are difficult to remove without special tools.

To vent fluids and gases trapped under the screw, these metric screws are drilled through the shaft.

Tighten these metric screws by turning them to the left; once fastened, they prevent loosening from counterclockwise motion.

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

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.

These metric 18-8 stainless steel screws have good chemical resistance and may be mildly magnetic. The flange is wider and thicker than our other flanged screws, so they distribute pressure the best.

Made from 18-8 stainless steel, these screws have good chemical resistance and may be mildly magnetic. A nylon patch bonded to the threads adds friction to prevent loosening from vibration.

These 18-8 stainless steel 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.

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.

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

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

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.

These shoulder screws have good chemical resistance.

With a hex socket at the tip as well as the head, you can fasten these shoulder screws from the tip when the head cannot be reached.

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

Install and remove these shoulder screws by hand or with a hex key.

These assortments include hex head screws and hex nuts.

Shoulder screws have a cylindrical shoulder under the head that allows parts to rotate around or slide along its length. They have a standard shoulder with an undersized tolerance to fit most machinery and equipment.
