HEX FLANGE NUT / SERRATED FLANGE NUT (DIN6923)

HEX FLANGE NUT / SERRATED FLANGE NUT (DIN6923)
HEX FLANGE NUTS; can either be serrated or non-serrated.
Serrated face nuts are more common. The serrated face can increase the contact surface area. The goal is to have lock nut mechanism.

INTERNATIONAL STANDARDS:

  • DIN6923
  • DIN EN 1661
  • ISO 4161
  • JIS B1190
  • IFI
  • ACCORDING TO CUSTOMER SPECIFICATION

PRODUCT APPLICATIONS

The flange may be serrated to provide a locking action.

Swivel flange nuts are mostly used in joining wood and plastic.

A self-aligning nut, also known as a spherical nut or leveling nut, is a type of nut that is used in applications where the fastener is not perpendicular to the surface the nut anchors to. It achieves this action by using a flange nut inside a specially shaped dished-out washer.

They are commonly used in the aerospace industry.

If this nut were not used the object would have to be spot faced perpendicular to the fastener.
