Self-locking nut DIN 980 M12 stainless steel A4

Product detailed description

The DIN 980 M12 stainless steel A4 self-locking nut is a hexagonal all-metal nut designed for applications where it is necessary to ensure a reliable and strong connection even when exposed to vibrations and higher loads. This nut is made of A4 stainless steel, which provides excellent corrosion resistance, making it suitable for use in harsh environments such as the chemical industry or marine applications.

The nut has a metric thread with a diameter of M12 and a pitch of 1.75 mm, which ensures compatibility with commonly used threaded rods and screws. Its height is 12 mm, the width between the surfaces (s) is 19 mm and the width between the diagonals (e) is 21.1 mm. These dimensions are in accordance with DIN 980 and ISO 7042 standards, which define the requirements for hexagon nuts with a locking effect.

The design of the nut includes a deformed threaded part that creates a self-locking effect. This mechanism ensures that the nut remains firmly in place even under dynamic loads, minimizing the risk of the joint loosening. Since it is an all-metal nut, it does not contain any plastic or other non-metallic parts, which contributes to its resistance to high temperatures and chemicals.

The nut is supplied without surface treatment, which is common for stainless steel materials, as their natural resistance to corrosion eliminates the need for additional protection. This feature, together with the A4 strength class, makes this nut an ideal choice for applications where high reliability and durability in harsh conditions are required.
