Spline

— spline can be described as a kind of dodecahedral head, the working surface of which is not a polygon, but a star with 12 rays. In addition to the standard advantages of a 12-point socket (for example, a small angle between the edges, which increases the number of possible tool positions during work), heads of this type are versatile — they are compatible not only with "native" bolt heads, but also with conventional 6- and 12 -faced, square, E-profile, etc. At the same time, when working with non-standard fasteners, care should be taken due to the increased likelihood of failure.
