The standard choice for fastening in wet and outdoor conditions. Made of 18-8 stainless steel, these screws resist corrosion from mild chemicals and water.

Use these kits to connect standard-size stainless steel pipe flanges for ANSI Class 150 or 300.

Made from 18-8 stainless steel, these screws have good chemical resistance. A flange under the head distributes pressure over the surface, eliminating the need for a washer.

For strength comparable to that of Grade 9 steel and the corrosion resistance of stainless steel, choose these screws. They are work-hardened for extreme strength. The flange eliminates the need for a separate washer.

Made from 18-8 stainless steel, these screws have the best chemical and corrosion resistance of our wire-lockable screws. Wire these screws together for more vibration resistance than other types of hex head screws.

An O-ring under the head 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.

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.

These screws have good chemical resistance. A thread locker bonded to the threads prevents loosening from vibration.

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.

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

Made from 18-8 stainless steel, these screws are chemical resistant.

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

Press threads into plastic to create a strong hold. Use a wrench, hex socket bit, or nutdriver to securely grip the hex head and tighten these screws.

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.

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

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

Stainless steel screws have excellent corrosion resistance in most environments.

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.

Made from 18-8 stainless steel, these 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.

To vent fluid and gas trapped under the screw, these metric screws are drilled through the shaft. Made from 18-8 stainless steel, they 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.

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

These shoulder screws are angled under the head to sit flush in countersunk holes.

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.

These assortments include button head screws.

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.
