Product detailed description

The flat set screw with a groove according to DIN 551, ISO 4766 and ČSN 021181 is a specific type of fastener designed for applications where precise adjustment and securing of the position of components is required. This type of screw is characterized by a flat end and a continuous groove, which allows easy adjustment using a screwdriver.

The dimensions of the screw are defined by the metric thread M3 with a diameter of 3 mm and a length of 3 mm. The groove diameter is 2 mm and the groove width (B1) is 1.5 mm. The screw has a metric thread with a pitch of 0.50 mm, which guarantees accuracy and reliability during adjustment.

The screw material is steel with a strength class of 14H, which provides high resistance to mechanical stress. The screw is supplied without surface treatment, which is suitable for applications where additional corrosion protection is not required.

This screw is ideal for use in mechanical assemblies where precise adjustment and positioning of components is required without the use of a head. Due to its properties, it is widely used in mechanical engineering and industrial applications where precision and reliability of the connection are important.
