Half as thick as regular hex nuts, these nuts fit into spaces with low height clearances. They are about half as strong as medium-strength steel, and are often used for light duty applications, such as securing access panels. Also known as jam nuts, they can be threaded together to form a locknut that won’t move or loosen due to vibration. When fastening threaded rod, you can use two nuts to create a point for tightening the rod with a wrench. These nuts have less tensile strength than a standard hex nut when used alone.
DIN 439 ISO4035 Hexagon Thin Nut
Use for
Thin hex nuts ISO 4035/DIN439 are used in bolted connections,
e.g. as lock nuts to lock components and prevent accidental loosening, turning or shifting.
In addition, the nuts are also used together with indexing plungers, cam action indexing plungers, guide bushings or rod end bearings.
