Metric shoulder screws come in various sizes, and their dimensions are typically specified by the diameter of the screw, the length of the shoulder, and the thread size. The dimensions are typically given in millimeters (mm).
For example, a common metric shoulder screw designation might look like this:
M6 x 20mm
This indicates a shoulder screw with a metric thread size of M6 (6mm diameter) and a shoulder length of 20mm. The "M6" refers to the thread size, and the "20mm" refers to the length of the unthreaded portion (shoulder) between the head and the threaded portion.
Sizes can vary widely, and you can find metric shoulder screws with different thread sizes (M4, M5, M6, etc.) and shoulder lengths to suit various applications. It's important to choose the right size and specifications based on the requirements of your specific project or application.
