Besides squares, what type of nut is used w machine screws?

• A. Oblong
• B. Hexagonal
• C. Round
• D. Octagonal

Answer: (B)

Hexagonal nuts are the standard choice with machine screws. The six flat sides give multiple wrench surfaces, so you can tighten securely with a wrench or socket from different angles, apply good torque without rounding the corners, and keep the nut aligned as you thread it on. Squares were used in the past, but they’re harder to grip and torque effectively. Round, oblong, or octagonal nuts aren’t as compatible with the common tools and fastener systems, so hex nuts fit best with machine screws.
