Metalliruuvi

Metalliruuvi is a Finnish term that translates to "metal screw" or "metal screw fastener." It refers to a type of screw specifically designed for use in metal or for fastening metal components together. These screws typically have threads that are sharper and more closely spaced than those found on wood screws, allowing them to cut into metal surfaces more effectively.

The material of a metalliruuvi is crucial for its application. They are often made from hardened steel, stainless steel, or brass, chosen for their strength, corrosion resistance, and compatibility with the materials being joined. The head types of metalliruuvi vary widely, including hex heads, pan heads, flat heads, and button heads, each suited for different assembly needs and aesthetic requirements.

Common applications for metalliruuvi include assembling machinery, constructing metal frames, attaching components in automotive and aerospace industries, and securing fixtures. They are often used in conjunction with nuts or tapped holes to create strong, permanent or semi-permanent joints. The specific type of metalliruuvi used will depend on the thickness of the metal, the required holding strength, and the tools available for installation.
