Nut left thread low DIN 439B M30x1.50 |04| zinc

Product detailed description

Low-profile left-hand thread nut according to DIN 439B, ČSN 021403 and ISO 4035 is designed for applications where it is necessary to ensure a connection in a limited space and at the same time require the opposite direction of the load. This nut has a metric left-hand fine thread with a diameter of M30 and a pitch of 1.50 mm, which allows for precise and reliable fastening in specific technical applications.

The height of the nut is 15 mm, which makes it one of the low nuts, suitable for applications with limited space above the connection. The width between the surfaces (s) is 46 mm and the width between the diagonals (e) is 50.85 mm, which corresponds to the standard dimensions for hexagonal nuts in this category.

The nut is made of steel with strength class 4, which means that it is suitable for less demanding applications where high strength is not required. The surface treatment is white zinc plating, which provides basic protection against corrosion and increases the resistance of the nut to external influences.

This nut is ideal for use in light joints where it is necessary to ensure reliable fastening with the opposite direction of load, for example in mechanisms with reverse movement or in applications where it is necessary to prevent spontaneous loosening of the joint due to vibrations or other dynamic loads.
