The Hirschmann GDM 3011-7 and GDM 3011-8 center screw are very similar. Both are size M3 x 35 and are made from steel with knurled heads. The GDM 3011-8 is mainly a predecessor to GDM 3011-7 and is discontinued, so it is limited to what is left in stock. The GDM 3011-7 is also available with either a gray or black head, while GDM 3011-8 is only available in gray.
