M8 x 90mm Hexagon Bolts (DIN 931) - A2 Stainless Steel Hexagon Bolts are very versatile screws, which are tightened and loosened with a spanner matching the head diameter (across the flats). Their Hexagonal Head allows for a great amount of torque to be applied to this screw making them ideal in heavy duty applications. Hexagon Bolts are partially threaded and have a section of plain unthreaded shaft below their head, whereas Hexagon Setscrews have a fully threaded shaft. These Hexagon Bolts are made from A2 Stainless Steel which provides corrosion and oxidation resistance.
