Notes
- A plain shank with a head on one end and a cross-hole for a split pin near the other. The shank length L is measured under the head, so each file is L plus the head height overall (Ø3 × 12 is 13 long, Ø8 × 40 is 43).
- Head Ø × height, cross-hole Ø and hole axis from the shank end, by pin Ø: 3 → 5 × 1, 0.8, 1.6; 4 → 6 × 1, 1.0, 2.2; 5 → 8 × 1.6, 1.2, 2.9; 6 → 10 × 2, 1.6, 3.2; 8 → 14 × 3, 2.0, 3.5.
- The shank is drawn at the pin Ø exactly. The holes it passes through on a clevis or link are drawn at the same Ø; which joints turn on the pin and which hold it fixed is listed under Mating features.
- The cross-hole takes an ISO 1234 split pin of the same nominal size (0.8 hole, 0.8 split pin). The R-clips in this library have a 1.2 wire, which passes the Ø1.2, Ø1.6 and Ø2.0 cross-holes of the Ø5, Ø6 and Ø8 pins.
