What is a cap bolt characterized by?

• A. A smooth shank with large cutting threads
• B. A flat point and threaded down the entire shank
• C. A round head with square shoulders
• D. A hexagonal head for wrenching

Answer: (B)

A cap bolt is specifically characterized by having a flat point and threads that run down the entire length of the shank. This design allows the bolt to be fully engaged in the material it is fastening, providing a strong hold. The flat point enables easier alignment and insertion into pre-drilled holes, ensuring precise fitting and stability in applications where a secure connection is vital.

In terms of design characteristics, a round head with square shoulders, which suggests a different type of fastener, does not apply here. Similarly, a hexagonal head, typically found on fasteners designed for use with wrenches, is not indicative of a cap bolt. The smooth shank with large cutting threads also reflects characteristics associated with another type of fastener, designed more for cutting into material than for securing it like a cap bolt would.
