Metallikiinnikkeet, or metal fasteners, are mechanical components used to join or affix materials together. They are widely utilized in construction, manufacturing, automotive, and various other industries due to their strength, durability, and ease of installation. Common types of metal fasteners include screws, bolts, nuts, washers, rivets, pins, and clips, each serving specific purposes depending on the application.

Screws and bolts are among the most frequently used fasteners. Screws typically have a threaded shaft and a head designed for turning with a tool, while bolts require a nut to secure them in place. Washers, often placed under the head of a bolt or screw, distribute the load and prevent damage to the surface being fastened. Rivets, on the other hand, are permanent fasteners that join materials by deforming under pressure, creating a secure bond without the need for threading.

In construction, metal fasteners are essential for assembling structural components like beams, columns, and frameworks. They must withstand significant stress and environmental factors such as corrosion, which is why materials like stainless steel, galvanized steel, or coated fasteners are often preferred. In automotive applications, fasteners ensure the integrity of engine parts, chassis, and body panels, where precision and reliability are critical.

The selection of the appropriate metal fastener depends on factors such as load requirements, material compatibility, environmental conditions, and ease of installation. Proper installation techniques, including correct torque application and surface preparation, are vital to ensure the longevity and performance of the fastened assembly. Advances in materials science and manufacturing have led to the development of specialized fasteners, such as self-tapping screws or high-strength alloys, further expanding their applications in modern engineering.
