  1. Right choice of steel alloy (4140 or 416), incorrect choice of the particular piece of steel.

    I’ve made hitch pins in the past for my tractors and such with 4140 QT steel. Worked fine. But you really do want to maximize the diameter of the pin – it’s not the pulling force that usually causes hitch pin failure, it’s hitting the brakes with a load behind the tractor that typically has no brakes of its own.
