2、leased originally to cover hexagon flange weld nuts capable of withstanding the proof load equivalent to a property class 10. Two styles of weld projections are included, elongated and round: Elongated projections are suitable for welding to relatively thin steel with and without light duty coatings
3、. Round projections are intended for welding to relatively thicker steel and steels with heavy duty coatings such as 60G60GHD. Before selecting the projection type Engineering should consult with the welding experts in Manufacturing to ensure that the correct projection shape is specified to meet ma
4、terial and welding equipment capability. The different projection types are available in a threaded version and an un-threaded version with a hole size suitable to accept thread forming screws. The design of these nuts is similar to nuts manufactured in accordance with ISO/FDIS 21670. FIGURE 1 Formi
