M5 Heavy Hex Nut to UNI 5587 in A2 Stainless Steel - UNI 5587

This high type nut is also known as a heavy hexagon nut. It follows the same dimensions as the DIN 934 hex full nut, but the thickness of the nut is greater. This gives the nut greater strength and thread engagement, making the joint more robust. The extra height of the nut makes them less likely to loosen or separate, as well as making it easier for the wrench to grip the nut, which in turn, allows for more torque to be applied.
