Universal joints allow turning a nut or bolt with the handle at an angle. They are available in which drive sizes?

• A. 1/4 inch, 3/8 inch, and 1/2 inch drive units
• B. 1/8 inch, 1/4 inch, and 3/8 inch drive units
• C. 3/16 inch, 1/4 inch, and 1/2 inch drive units
• D. 1/2 inch, 3/4 inch, and 1 inch drive units

Answer: (A)

Drive sizes are the square shanks that fit into a ratchet, so universal joints must come in the standard drive sizes that tools use. The most common and widely available options are 1/4 inch, 3/8 inch, and 1/2 inch drive units. This set covers small, medium, and large fasteners and matches the drives on typical ratchets. Smaller drives like 1/8 inch or 3/16 inch aren’t as standard for universal joints in everyday tool kits, while larger drives like 3/4 inch or 1 inch are uncommon for standard hand tools. So the best-supported combination is 1/4, 3/8, and 1/2 inch drive units.
