NE Retaining Nut

This series was the continuance of the original SAE series developed at the turn of the century. In 1930, after years of use indicated the original thread design was not the most practical and economica, the sizes 15 through 40 of this series were changed from eleven threads per inch to the twelve or eight threads per inch and designated AN rather than N.

This series is provided for maintenance and repair operations of equipment manufacture many years ago. They are increasingly expensive because of declining demand. WHITTET-HIGGINS, however, as the full line manufacturer will continue to provide them to service fully the needs of industry.
