Screw lens head - groove DIN 964 M4x25 galvanized

Product detailed description

The countersunk lens head screw with a slot according to DIN 964, ISO 2010 and ČSN 021155 is designed for applications requiring an aesthetic appearance and a reliable connection. This screw has a metric thread M4 and a length of 25 mm. It is made of steel with a strength class of 4.8, which means that it has a yield strength of 320 MPa and a tensile strength of 400 MPa. The surface treatment is performed by galvanizing, which provides increased resistance to corrosion.

The screw head is lens-shaped and countersunk, which allows it to be embedded in the material so that it does not protrude above the surface, thus achieving a smooth and aesthetic surface. The slot in the head is designed for use with a flat screwdriver, which simplifies assembly and disassembly. This type of screw is often used in mechanical engineering, furniture manufacturing and equipment manufacturing, where it is necessary to ensure a strong and aesthetically clean connection.

The screw is part of a group of fasteners known as countersunk screws with a lenticular head, which are ideal for applications where the appearance and functionality of the joints are important. Thanks to its properties, it is suitable for use both indoors and outdoors, while the zinc layer provides protection against corrosive environmental influences.
