Cylindrical head screws with hexagonal sockets are widely used in engineering, manufacturing, and a variety of applications. These screws have a specific design with a cylindrical head that can vary in height, and an even thread along the length of the shank.

One of the most recognizable features of these screws is the hexagonal socket in the head. This socket allows for the use of hex keys for installation and removal, providing high torsion resistance and excellent control during assembly.

These screws are available in a wide range of metric sizes, with different thread pitches (such as M3, M4, M5, etc.), lengths and materials (often carbon steel or stainless steel). The choice of size and material depends on the specific requirements of the application, such as load capacity, corrosion resistance and durability.

Cylindrical head screws with hexagonal sockets are widely used in applications that require a solid and stable connection. These may include the fixing of mechanical components, assembly of machinery or furniture, construction of metal structures and much more. Thanks to their precise design and dimensional versatility, these screws have become a key element in engineering and manufacturing.

Other sizes and galvanic finishes are available by request.
