Åtdragningsvärde

Åtdragningsvärde is a Swedish term that translates to "tightening torque" in English. It refers to the specified rotational force applied when fastening a threaded component, such as a bolt or screw, to a particular level of tightness. This value is crucial in mechanical engineering and assembly to ensure proper joint function, prevent over-tightening or under-tightening, and maintain the integrity and safety of the assembled parts.

The åtdragningsvärde is typically measured in units of torque, such as Newton-meters (Nm) or foot-pounds (lb-ft). It is determined by factors including the size and thread pitch of the fastener, the materials being joined, and the intended application. For instance, a higher åtdragningsvärde might be required for structural components that experience significant stress, while a lower value might be suitable for less critical applications to avoid damaging delicate materials.

Achieving the correct åtdragningsvärde is usually done using a torque wrench, a specialized tool that indicates or limits the amount of torque applied. Engineers and technicians must adhere to these specified values to guarantee that fasteners are neither too loose, which could lead to slippage or failure, nor too tight, which could strip threads, fracture the fastener, or damage the workpiece. Maintaining the correct åtdragningsvärde is fundamental for the reliability and longevity of mechanical assemblies.
