Studs - Metal end ≈ 1d, 1.25 d, 1.5 d, 2d

This standard has been drafted in a way to highlight the studs with an installation length of 1.5 d, the most commonly used. However, it was useful to also provide in this standard studs with implantation lengths of 1 d, 1.25 d and 2 d which correspond to more specific needs.
