Hexagon cap nuts high form DIN 1587-brass chrome-plated M12

The wrench sizes for hexagon bolts and nuts are specified in ISO 272: 1982-01. The nominal wrench size on the workpiece (e.g. bolt, nut) is the same as that on the tool. However, there is some play between the two to allow the tool to be fitted without difficulty. The relationship between the nominal diameter d of the thread and the wrench size s is standardised in EN ISO 4014 and EN ISO 4017 for hexagon bolts, and in EN ISO 4032 for hexagon nuts (dimensions in mm).

Chrome plating is carried out in accordance with DIN EN ISO 1456 Metals such as steel, stainless steel, aluminum, bronze, iron, brass, copper and die-cast zinc can be chrome-plated. The chrome surface is applied to a thick nickel undercoat. This is a durable and robust application that is less susceptible to wear and scratches.
