To fasten flanges and fittings inside pipes, you need various screws, washers and nuts. We offer stainless steel screws A2 with thread in sizes M10 - M30 and screws in lengths 40 - 120 mm, also steel screws with lengths 32 - 240mm. The nuts and washers are also available in both materials. Thanks to these three components, it is particularly easy to install a fitting to a flange.
