DIN 6331

Hex Nuts

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.
