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.
316 stainless steel fasteners are more corrosion resistant than 18-8 stainless steel fasteners and have excellent resistance to chemicals and salt water.
