Get the exact metric size your work demands. This 21 mm socket is engineered for use with pneumatic and cordless impact tools, providing the depth necessary to engage fasteners that sit deep on studs or extend well past the nut face. Mid-range metric sizes handle the bulk of automotive fastening, from lug nuts and caliper brackets to control-arm bolts and transmission-case hardware. The deep well body reaches where a shallow socket cannot, and the DIN-standard dimensions ensure the socket sits squarely on the hex without play. That tight fit matters most under high torque, where even slight slop can round a fastener and turn a five-minute job into a recovery operation. Sold individually so you replace only the size that is worn, cracked, or lost. Most complete sets include these mid-range sizes, but they are also the first to fail because they see the most action. A single replacement keeps your tray complete at minimal cost. Pair this socket with any half-inch ratchet, breaker bar, or torque wrench for controlled tightening when impact force is not appropriate. It also integrates with the Teng Tools get-organized storage system, fitting neatly into labeled trays and wall racks to keep your shop running efficiently.
