What are the most prevalent sizes of wrenches?
1/4 inch and 3/8 inch wrenches are commonly used for mild and light tasks. Ratchet drivers, on the other hand, are 1/2 inches long. Heavy-duty wrenches, on the other hand, are larger than medium and light-duty wrenches. For heavy-duty operations, ¾ inch and 1-inch wrenches are the right sizes.
