Hexagon nuts DIN 6331 are used on clamping applications which require frequent clamping and unclamping (m = 1.5 x d1).
The collar of the nut eliminates the need for washers.
The official standard sheet specifies the additional sizes M 27, M 42 and M 48. But M 14 is not forseen on the official standard sheet.
Size M10 with A/F = 17
