Which fastener is used for shear load and is secured with flat washer and cotter pin?

• A. Rivet
• B. Clevis Pin
• C. Wing Nut
• D. Plate Nut

Answer: (B)

The fastener designed for shear loads and secured with a flat washer and cotter pin is the through pin used in hinge-like connections. This type of pin goes through aligned holes in the parts being joined, carrying the load mainly in shear as the two pieces slide laterally past each other on the pin. A cotter pin is inserted through a hole in the pin’s shank to lock it in place and prevent it from pulling out, while a flat washer helps spread the load and protect the hole surfaces from wear. Rivets are permanent and don’t use cotter pins, wing nuts rely on threads for retention, and plate nuts are threaded inserts rather than removable, pin-secured joints.
