Materials & strength

Insert locking with load spread

The nylon collar resists vibration loosening while the integral flange spreads the clamping load like a built-in washer.

Frequently asked

What is a DIN 6926 flange nut?

DIN 6926 covers hexagon flange nuts with a nylon locking insert, combining the washer-like bearing face of a flange nut with nylon insert-style resistance to loosening. It suits vibration-prone joints where load spreading is also wanted.

What is the difference between DIN 6926 and ISO 7043?

The standards are closely related, although dimensional or technical differences may exist. If your drawing specifies ISO 7043, send us the requirement and we can identify the appropriate product.

How does DIN 6926 differ from DIN 6923?

DIN 6923 is an all-metal flange nut whose serrated version locks by biting into the surface, while DIN 6926 locks through a nylon insert and is less likely to mark the mating face than a serrated flange. The choice usually comes down to surface finish and service temperature.
