If you can’t find a cotter pin that fits the exact length requirements of your item, choose a larger-sized cotter pin and cut the materials down to the ideal size. Length: Look at the length of the holes you need to secure and compare this number to the shortest leg of the cotter pin - the length of the hole should be shorter than both cotter pin prongs to ensure the cotter pin performs effectively and dependably.Head size: Find a cotter pin head size that is large enough to prevent the pin from moving over time with constant vibrations but no so large that it could prevent movement of other pieces or that it could become jammed.Width: Measure the diameter of the hole where the cotter pin needs to fit, and find a pin in the biggest possible size to fit in the corresponding material hole.When choosing the best cotter pin for your application, consider: Pin lengths range from ¼ inch to 6 inches.
