hexpääruuvit

Hexpääruuvit, also known as socket head cap screws or Allen screws, are a type of fastener characterized by a cylindrical head with a hexagonal socket for driving. This hexagonal recess allows for high torque application compared to slotted or Phillips head screws. The design facilitates installation in recessed areas where a standard screwdriver might not fit.

The primary advantage of hexpääruuvit is their ability to transmit significant rotational force without the driver slipping out of the socket, which is a common issue with other screw types. This makes them ideal for applications requiring a strong and secure fastening. They are commonly manufactured from steel, often with various plating or hardening treatments to enhance strength and corrosion resistance. Stainless steel variants are also available for environments prone to rust.

Hexpääruuvit are widely used across numerous industries, including automotive, aerospace, machinery, and furniture manufacturing. They are essential in machine assembly, structural components, and anywhere a flush or low-profile head is desired. The size of the screw and the corresponding hex key or driver are standardized, ensuring interchangeability. Removal and installation are typically done using an L-shaped Allen wrench, also known as a hex key.
