___ nails are made from hardened steel to prevent them from bending when being driven into concrete or other masonry.

• A. Box
• B. Bright
• C. Common
• D. Masonry

Answer: (C)

Hardness and stiffness matter when you drive a nail into concrete or brick. Masonry nails are made from hardened steel to resist bending as they punch into hard masonry and secure into place. That toughness helps the nail stay straight and hold up under the forces of mortar and hard substrates. Other nails meant for wood or finishing work are softer or thinner and can bend or fail when used in masonry. So, nails designed specifically for masonry, with hardened steel construction, are the appropriate choice for concrete or brick.
