Loose bolts/nuts/washers M33 acid-resistant or galvanised

M33 bolts, nuts and washers are sold here as loose components, so you can assemble exactly the bolt set the flanged joint requires without ordering complete kits. The bolts are available in lengths from 140 to 220 mm, covering different flange thicknesses and gaskets with the same thread. The components are available in acid-resistant A4 or galvanised steel, so the design can be chosen to suit the environment around the joint. M33 is the bolt size used in several larger flanged joints, including PN10 in DN1000, PN16 in DN600 and DN700, and PN25 in DN400 to DN500. A washer is used against the nut during installation, and the number of bolts per flange is determined by the flange's size and pressure class.
