Flanged Stover Nut (DIN 6927)

DIN 6927 Flanged Stover Nuts are hex all-metal prevailing torque self-locking nut with an integrated washer. It is sometimes referred to as being ‘washer faced’.

In brief, this locknut is:

  • An all-metal prevailing torque self-locking nut, with an incorporated non-spinning washer.
  • A flange nut version of the DIN 980V Stover Nut.
  • Reusable.

The flange further reduces the risk of this nut loosening – and the nut is considered vibration resistant.

The self-locking function of this Flanged Stover Nut is still effective after a number of applications, meaning that it can be reused many times and remains resistant to shocks, vibration and dynamic loads. The integrated washer distributes the load over the covering area of the application, further reducing the risk of loosening over uneven surfaces.

The locking function is achieved by the deformation of part of the nut, and the nut will run smoothly until it reaches the deformed part, when the clamping force subsequently increases.

Available in Steel grades 8, 10 and 12, with thread diameters ranging from M5 to M20 in standard pitch, fine pitch and extra fine pitch.

Non-standard sizes, materials and finishes are available to order as specials, including small volume manufacture, modifications and custom parts made to drawings.
