About This Item

 

Full Description

This International Standard specifies the dimensions of plain, hexagonal nuts, reduced height, reduced across flats. with MJ threads, of classifications: 450 MPa1)/425 C2), 600 MPa1)/235 C2), 600 MPa1)315 C2), 600 MPa1)650 C2), 900 MPa1)235 C2), 900 MPa1)730 C2) and 1100 MPa1)/GOO C2).

Nuts provided with holes are intended to be used with lockwire in conformity with ISO 245.

This International Standard is only applicable for the compilation of aerospace product standards.

1) Corresponds to the minimum tensile stress which the nut is able to withstand at ambient temperature without breaking or cracking when tested with a bolt of a higher strength class.

2) Maximum temperature that the nut is able to withstand, without permanent alteration to its original characteristics, after ambient temperature has been restored. The maximum temperature is conditioned by the material or by the surface treatment.
