Our range of special grades of bolts, nuts, screws gives an impression of GNS Nederland’s capabilities. Heat-resistant or (highly) creep resistant grades in, for example, hexagon socket head cap screws (DIN912), hexagon bolts (DIN931 or DIN933), washers (DIN125, DIN127 or DIN9021), countersunk screws with hexagonal head (DIN7991), hexagon nuts (DIN 934, DIN 985, DIN 6923, DIN 1587) or threaded rods (DIN 975/DIN 976)? Our range is both wide and deep, and given the enormous diversity of dimensions, only available versions are mentioned. Materials always come from renowned manufacturers where no concessions are made on quality.
