kuusiokantaruuvit

Kuusiokantaruuvit, also known as socket head cap screws or Allen bolts, are a type of fastener characterized by a cylindrical head with a hexagonal socket for driving. The socket, also known as a hex socket or Allen key drive, is typically engaged by a hexagonal wrench, often referred to as an Allen key. This design allows for the application of torque with a tool that inserts into the head, providing a neat and compact fastening solution.

These screws are manufactured from various materials, including steel alloys (such as alloy steel, stainless steel, and carbon steel), brass, and aluminum, offering a range of strength and corrosion resistance properties. They are commonly produced to specific international standards, like DIN 912 or ISO 4762, which define their dimensions, thread types, and material specifications.

The primary advantage of kuusiokantaruuvit lies in their ability to be used in applications where space is limited or where a flush or counter-sunk finish is desired. The cylindrical head can sit flush with the surface of the material being fastened, or it can be seated within a counterbore. This makes them popular in machinery, automotive components, electronics, and furniture manufacturing. Their relatively high tensile strength and the secure grip provided by the hexagonal socket contribute to their widespread use in various industrial and domestic applications.
