Sizing for cotter pins is determined by which two factors?

• A. Length and diameter
• B. Width and strength
• C. Thickness and weight
• D. Diameter and material

Answer: (A)

Sizing for cotter pins primarily depends on their length and diameter. The length of the cotter pin ensures it fits properly within the application, providing enough reach to secure the components effectively. If the pin is too short, it won’t be able to perform its function correctly, while if it’s too long, it may protrude unnecessarily and create a hazard. Diameter is equally critical, as it has to fit snugly in the hole of the components it is meant to secure. If the diameter is too small, the cotter pin won't hold the parts together securely, and if it's too large, it may not fit at all or could cause damage to the installation area. The other factors listed, such as width, strength, thickness, weight, and material, may play roles in the overall performance and durability of the cotter pin, but they are not primary determinants in the sizing process. Sizing focuses specifically on ensuring a proper fit for the application at hand, which is why length and diameter are the essential measures.
