Screw lens head - groove DIN 964 M8x25 galvanized

Product detailed description

The lens-shaped head and slotted screw according to DIN 964, ISO 2010 and ČSN 021155 is designed for applications where it is necessary to achieve an aesthetic appearance and at the same time ensure a strong connection. This screw has a metric thread M8 and a length of 25 mm, which makes it suitable for a wide range of industrial and construction applications.

The screw head is lens-shaped, which means that it has a slightly convex shape that allows it to be embedded in the material, while the surface remains smooth. The slot on the head is designed for use with a flat screwdriver, which is a traditional and frequently used method of assembly.

The screw material is steel of strength class 4.8, which means that it has a yield strength of 320 MPa and a tensile strength of 400 MPa. This strength class is suitable for applications where extreme demands are not placed on mechanical resistance, but reliability and consistent quality are required.

The surface treatment of the screw is electroplating, which provides protection against corrosion and increases resistance to external influences. This treatment is ideal for use in environments where exposure to moisture or other corrosive substances may occur.

The screw is part of the group of fasteners with countersunk heads, which means that it is designed so that after installation it does not protrude above the surface of the material into which it is fastened. This is especially advantageous in cases where a smooth surface or aesthetic appearance of the structure is important.
