Kuusiokoloruuvinvääntimet

Kuusiokoloruuvinvääntimet, also known as Allen keys or hex keys, are hand tools used to drive bolts and screws with hexagonal sockets in the head. They are typically made of hardened steel and are L-shaped. The longer end is used for greater torque, while the shorter end can be used in tighter spaces or for faster turning. The hexagonal shape of the tool fits precisely into the corresponding socket, providing good grip and reducing the chance of stripping the screw head.

These tools are commonly found in many applications, from assembling furniture and bicycles to working with electronics and machinery. Their simple design makes them durable and relatively inexpensive. Kuusiokoloruuvinvääntimet come in various sizes, measured by the width of the hexagonal head across the flats. Metric sizes are prevalent in Europe and Asia, while imperial sizes are common in North America. Sets of kuusiokoloruuvinvääntimet often include a range of sizes to accommodate different fasteners. Specialty versions, such as T-handle kuusiokoloruuvinvääntimet or ball-end kuusiokoloruuvinvääntimet, are also available for specific tasks. The ball-end type allows for angled insertion into the socket, which can be useful for reaching fasteners in difficult locations.
