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.
Zinc-plated steel fasteners resist corrosion in wet environments.
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.

Stainless Steel Heavy Hex Screw and Nut Kits for Pipe Flanges
Connect standard-size stainless steel or aluminum pipe flanges with these kits—they come with screws and nuts in the right size and number to match the bolt holes. The screw heads and nuts are 10% wider than standard hex fasteners, so they spread force over a larger area, and you can tighten with more torque. Made from 316 stainless steel, the fasteners in these kits have excellent resistance to chemicals and salt water. They may also be mildly magnetic. For a complete connection, you’ll also need a gasket. Screw length is measured from under the head.
All screws and nuts meet ASTM A193 or A194 standards for high-pressure and high-temperature applications. They also meet ASME B18.2.1 standards for dimensions.

Oil-Resistant Aramid/Buna-N Pipe Gaskets with Bolt Holes and Fasteners
Each gasket comes with enough bolts and nuts to create a connection between two steel pipe flanges. Commonly called full-face gaskets, they cover the entire face of flat-surface pipe flanges and align with the bolt holes. They’re made from blended aramid fiber/Buna-N rubber and resist oil, water, and aliphatic hydrocarbons such as ethylene.
Gaskets for ANSI class flanges are sized so all gasket specifications meet ANSI standards. Gaskets for ANSI Class 150 flanges are compatible with low-pressure pipe flanges. Gaskets for ANSI Class 300 flanges are compatible with medium-pressure pipe flanges.
Gaskets for DIN flange sizes are sized to fit pressure class PN16 flanges.
Adhesive-back gaskets stay in place to make installation easier.

Oil-Resistant Aramid/Buna-N Pipe Gaskets with Fasteners
Furnished with enough nuts and bolts to create a connection between two steel pipe flanges. These gaskets, also known as ring gaskets, are for use on raised-surface pipe flanges; they fit the surface inside the bolt holes and do not interfere with the bolt connection. They’re made from blended aramid fiber/Buna-N rubber and resist oil, water, and aliphatic hydrocarbons such as ethylene. Gaskets are compatible with low-pressure pipe flanges; all gasket specifications are sized to meet ANSI standards.
