Adapters are devices that change the drive size of the handle or socket; they may change from small to large or from large to small. They are available for all socket sets. In which directions can adapters change drive size?

Adapters are devices that change the drive size of the handle or socket; they may change from small to large or from large to small. They are available for all socket sets. In which directions can adapters change drive size?

• A. Small to large or large to small
• B. Only small to large
• C. Only large to small
• D. They cannot change drive size

Answer: (A)

Adapters are designed to let you connect sockets to tools that have different drive sizes, and they work in both directions. They have a square drive on each end, but the sizes differ, so you can step up or step down as needed. For example, you can use a 1/4-inch drive ratchet with 3/8-inch sockets by using a 1/4-to-3/8 adapter, or you can use a 3/8-inch drive ratchet with 1/4-inch sockets by using a 3/8-to-1/4 adapter. This flexibility is why adapters are found in many socket sets—they let you mix sizes without buying separate handles for every socket.
