Nut with collar DIN 6923 M20 |08| zinc

Product detailed description

The collar nut according to DIN 6923 and ISO 4161 is a hexagonal connecting element with a metric thread M20. This nut is made of steel with a strength class of 8, which guarantees its high resistance to mechanical stress. The surface treatment is white zinc plating, which provides increased corrosion protection, thereby extending the service life of the component in harsh conditions.

The nut has a diameter d of 20 mm and the total diameter of the collar d1 is 42.8 mm. The height of the nut is 20 mm, the width across the surfaces (s) is 30 mm, the width across the edges (e) is 32.95 mm and the width of the collar (c) is 3 mm. The metric thread has a pitch of 2.50 mm, which is standard for this type of thread and allows a reliable connection with compatible screws.

The collar on the nut increases the contact surface, effectively distributing the pressure over a larger area. This allows the nut to be used without the need for additional washers, which simplifies assembly and reduces the risk of the joint loosening during vibration. This design is particularly suitable for applications where joints are subject to dynamic stress.

The DIN 6923, ISO 4161 and EN 1661 standards, according to which the nut is manufactured, guarantee that the component meets internationally recognized standards of quality and precision. This nut is ideal for use in various industrial sectors where high reliability and durability of joints are required.
