Stainless Steel Hex Screw and Nut Kits for Pipe Flanges
Join standard-sized stainless steel and aluminum pipe flanges in corrosive conditions. These kits come with the right size and number of screws and nuts for the bolt holes in each pipe size. For a tight seal, you’ll also need a gasket between the flanges. All screws and nuts meet ASTM and ASME standards or DIN standards for material quality and dimensions. They may be mildly magnetic. Screw length is measured from under the head.
18-8 stainless steel fasteners resist corrosion from mild chemicals and water. They are ideal for wet environments.
316 stainless steel fasteners are more corrosion resistant than 18-8 stainless steel fasteners and have excellent resistance to chemicals and salt water.
Kits with blue PTFE-coated nuts thread together with the screws smoothly thanks to the slippery coating on the nut. The coating also resists chemicals, so it doesn't compromise their corrosion resistance.

Hex Head Screw, Nut, and Washer Kits for Plastic Pipe Flanges
Use these kits to connect plastic pipe flanges—they’re sized for Class 150 flanges made to ASME B16.5 dimensions. They come with screws, nuts, and washers that match the size and number of bolt holes for each pipe size. For a complete connection, you’ll also need a gasket. All screws and nuts meet ASTM specifications for material quality and ASME specifications for dimensions. Washers distribute the pressure from a tightened nut over the surface of the flange, which helps prevent damage. Screw length is measured from under the head.
18-8 stainless steel fasteners are more corrosion resistant than zinc-plated steel fasteners and ideal for wet and outdoor environments. They have good chemical resistance and may be mildly magnetic.

18-8 Stainless Steel Flanged Hex Head Screws
Made from 18-8 stainless steel, these screws have good chemical resistance and may be mildly magnetic. The flange distributes pressure where the screw meets the surface, so you don’t need a separate washer. All screws meet ASME, IFI, or DIN specifications for dimensions. Head height includes the flange. Length is measured from under the flange.
Black-oxide screws have a dark, matte coating for a finished look.
Match the thread spacing of mating components. Coarse threads are the industry standard; choose these screws if you don’t know the pitch or threads per inch.

Super-Corrosion-Resistant 316 Stainless Steel Flanged Hex Head Screws
More corrosion resistant than 18-8 stainless steel screws, these 316 stainless steel screws have excellent resistance to chemicals and salt water. They may be mildly magnetic. The flange distributes pressure where the screw meets the surface, so you don’t need a separate washer. Head height includes the flange. Length is measured from under the flange.
All screws meet ASME, IFI, or DIN specifications for dimensions. Screws that meet ASTM F593 specifications comply with testing standards for material quality.
Match the thread spacing of mating components. Coarse threads are the industry standard; choose these screws if you don’t know the pitch or threads per inch. Fine threads are closely spaced to prevent loosening from vibration.

18-8 Stainless Steel Hex Head Screws with Nuts and Washers
Everything you need to make a complete joint in wet and outdoor conditions. These screws come with compatible nuts and washers. Made of 18-8 stainless steel, they resist corrosion from mild chemicals and water. They may be mildly magnetic. Washers distribute the pressure from a tightened nut over the surface of your material, which helps prevent damage. All screws and nuts meet ASTM specifications for material quality and ASME specifications for dimensions. Screw length is measured from under the head.

Hex Head Screw, Nut, and Washer Assortments
Keep the most common sizes of hex head screws, nuts, and washers on hand. The length of the screws is measured from under the head.
Assortments with multiple thread sizes help you replace damaged fasteners when you don’t have a thread checker handy—just test out sizes until you find what you need. Assortments with one thread size include screws in a variety of lengths.
18-8 stainless steel fasteners are more corrosion resistant than zinc-plated and zinc yellow-chromate plated steel fasteners, so they’re better for outdoor use. They have good chemical resistance and may be mildly magnetic.
316 stainless steel fasteners are more corrosion resistant than 18-8 stainless steel fasteners. They have excellent resistance to chemicals and salt water, and they may be mildly magnetic.
Match the thread spacing of mating components. Coarse threads are the industry standard; choose these fasteners if you don’t know the pitch or threads per inch.

Flanged Hex Head Screw and Nut Assortments
Keep a variety of flanged screws and nuts on hand so you always have the size you need. The flange distributes pressure where the fastener meets a surface, so you don’t need a separate washer. They come in a metal box with a removable tray. Screw length is measured from under the flange.
18-8 stainless steel fasteners are ideal for wet and outdoor environments. They have good chemical resistance and may be mildly magnetic.
