3/8" Sockets
3/8 inch drive sits right in the sweet spot between the fiddly 1/4 inch and the bulky 1/2 inch, which is why it's the go-to size for most general mechanical work. This range covers standard and deep 3/8 inch sockets, impact-rated sockets built to handle powered tools, and oil filter socket sets and wrenches for routine servicing. Sealey and Draper offer strong value across single sockets and boxed sets, while Milwaukee and Laser add options built for tougher, more frequent use. Buy individual sizes to fill gaps in an existing set or a complete set to start from scratch — everything's in stock with fast dispatch.
