Which fastener is used in high shear, low tension stress areas?

• A. Clevis Bolt
• B. Eye Bolt
• C. Fillister
• D. Plain Washer

Answer: (A)

When a connection is expected to take mainly shear rather than pulling apart in tension, you pick a fastener whose strength comes from the shear plane. A clevis bolt is designed for this kind of loading: the shank carries the load in shear as parts slide past each other, providing solid shear resistance and keeping the joint from relying on the threaded portion to carry the load. Eye bolts, by contrast, are intended for lifting where tension is primary, so they are not optimal for shear and can fail where shear is dominant. Fillister head screws and plain washers don’t offer the same reliable shear performance in joints: a fillister head screw is a small machine screw not specialized for high shear, and a plain washer merely distributes load without acting as a fastener itself.
