HAND TOOLS

1. Mark needs to drive a nail into a wooden board, but he notices that the nail keeps bending when he strikes it. What should Mark do to avoid this problem?

• Strike the nail at an angle to avoid bending.
• Use a hammer with more force.
• Use a hammer with a larger head and hit the nail squarely.

• Choose a larger nail without pre-drilling.

Answer explanation

A larger hammerhead distributes force more evenly, and striking the nail squarely reduces the chance of bending.
