Self-locking nut DIN 985 M20 stainless steel A4

Product detailed description

The self-locking nut DIN 985 M20 made of A4 stainless steel is a hexagonal nut with an integrated nylon insert, which serves to prevent self-loosening. This design is particularly suitable for applications where joints are exposed to vibrations and dynamic loads. The nylon insert creates additional friction on the thread, thereby increasing resistance to loosening.

The nut is manufactured according to DIN 985, which is equivalent to ISO 10511 and ČSN 021492. It has a metric thread with a diameter of M20 and a pitch of 2.50 mm. The height of the nut is 14 mm and the total height including the nylon insert is 20 mm. The width between the faces (s) is 30 mm, while the width between the peaks (e) is 32.95 mm.

The material used for manufacturing is A4 grade stainless steel, which provides excellent corrosion resistance, making it ideal for use in harsh environments, including the chemical industry and marine applications. The nut has no additional surface treatment, which is typical of stainless steel components that rely on the natural resistance of the material.

This nut is part of the category of fasteners used for the safe and reliable fastening of components in various industrial sectors. Due to its properties, it is ideal for applications where it is necessary to ensure the strength and stability of the joint even when exposed to adverse conditions.
