Ratchet Wrench

A ratchet wrench, also known as a socket wrench or ratchet, is a hand tool designed for turning nuts and bolts. It typically consists of a handle, a ratcheting mechanism, and a socket that fits onto the fastener. The ratcheting mechanism allows the user to turn the fastener in one direction while the tool remains engaged, making it more efficient than traditional wrenches that require the user to lift and reposition the tool for each turn. This design enables faster and more convenient tightening or loosening of nuts and bolts in various applications, such as automotive repair, construction, and general maintenance.

Universal Socket Wrench

A universal socket wrench, also known as a universal socket or universal joint socket, is a versatile hand tool designed for turning various types of fasteners, such as nuts and bolts. Its distinctive feature is the presence of a universal joint mechanism, allowing the socket to articulate and flex at different angles. This flexibility enables the wrench to access fasteners in tight or awkward spaces where a regular socket wrench might be challenging to use. Universal socket wrenches typically have a square drive on one end for attaching different-sized sockets, providing adaptability to a range of fastener sizes and types.
