Clevis pin with head (ISO 2341 / DIN 1444)
Clevis pin with head, type A (plain) or type B (with a split-pin hole), d 4 to 24 mm, any length, with catalogue sizes as presets (type B).
Geometry
Head of diameter dk and height k; shank of the nominal diameter d and length l under the head; for type B a cross hole d1 for the split pin, its axis le (min) from the end. The head's edge radius and the shank's end chamfer are not modelled. The head's bearing face is on the XY plane at the origin, the head above it, the shank along -Z; the cross hole runs along Y.

ISO 2341:1986, Clevis pins with head, dimension table: dk (h14), k (js14), d1 (H13), le min (mm), read from the reproductions at https://www.globalfastener.com/standards/detail_252.html (with the tolerance limits, which confirm k 5.5 for d 22 and 6 for d 24) and https://www.fasteners.eu/standards/ISO/2341/. fasten.it's DIN EN 22341:1992-10 page gives k 5 and 6.3 for d 22 and 24 (the d1 values, apparently shifted into the k column); the ISO 2341 values are used.
