A hex socket set is a collection of tools used for tightening and loosening bolts and nuts with hexagonal heads. The set typically includes a range of hex sockets of different sizes, along with a socket wrench or ratchet handle for turning the sockets.
Hex socket sets can include a range of sizes, typically ranging from 4mm to 19mm or larger. Some sets may include smaller or larger sizes depending on the intended use.
Hex socket sets are commonly made from chrome vanadium steel, which is a durable and high-strength material that is resistant to wear and tear. Other materials such as carbon steel, stainless steel, and impact-resistant materials may also be used depending on the intended use and application.
