Torquejuhised

Torquejuhised, a term originating from Estonian, translates loosely to "torque instructions" or "torque guidelines." In a technical context, it refers to the specific tightening values or sequences required for fasteners, such as bolts and nuts, to ensure proper assembly and functionality of mechanical components. Adhering to torquejuhised is crucial for preventing both under-tightening and over-tightening. Under-tightening can lead to loose connections, vibrations, and potential failure, while over-tightening can strip threads, deform parts, or even cause breakage.

These instructions are typically found in technical manuals, assembly guides, or engineering specifications for various products, ranging from automotive engines and bicycle parts to industrial machinery and aerospace components. Torquejuhised are usually expressed in units of torque, such as Newton-meters (Nm) or foot-pounds (lb-ft), and may also include specific tightening sequences, especially for multi-bolt applications like cylinder heads or wheel hubs, to ensure even pressure distribution. The precise torque values are determined by engineers based on factors like the material strength of the fastener and the connected components, the desired clamping force, and the operational environment.

Using a calibrated torque wrench is essential for accurately applying the specified torque. Deviations from the recommended torquejuhised can compromise the integrity and safety of the assembled product. Therefore, skilled technicians and mechanics meticulously follow these guidelines during assembly, maintenance, and repair operations to guarantee reliable performance and longevity.
