Justeringsstift

Justeringsstift, also known as adjusting pins or setting pins, are small mechanical components used to make fine adjustments to the position or tension of other parts. They are commonly found in mechanical devices, musical instruments, and precision engineering applications. The primary function of a justeringsstift is to allow for precise control over a mechanism's alignment or pressure.

In musical instruments, such as stringed instruments, justeringsstift are crucial for tuning. They are typically threaded and are turned to increase or decrease the tension on the strings, thereby altering the pitch. The fine threading allows for very small adjustments, enabling accurate tuning. Similarly, in mechanical clocks and watches, justeringsstift are used to regulate the rate of the mechanism, affecting how fast or slow the timepiece runs.

In industrial and manufacturing settings, justeringsstift can be employed to set the clearance between moving parts, calibrate sensors, or provide a stable reference point. Their design often involves a threaded shaft that screws into a tapped hole, with a head or tip that contacts the component requiring adjustment. The precision of the threads and the stability of the material are critical factors in the effectiveness of a justeringsstift. The term can also refer to pins used in optical equipment for aligning lenses or mirrors.
