A ratchet spanner is an interchangeable set of sockets

Ratchet spanners are an affordable and convenient alternative to traditional square head sockets. They have 72 finely geared positions that make tightening and loosening easy. They are also available in a wide range of sizes.

Ratchet spanners are more cost-effective than square-head sockets
A ratchet spanner is an interchangeable set of sockets, which eliminates the need to buy separate tools for different types of fasteners. Socket sets are available for virtually every type of screw, and they often include a ratchet of the same "set size" in the package. They can also handle a variety of different sizes of bolts and nuts. They are more convenient to use than individual tools.

The hex form is more versatile than the square head and makes wrenching easier in confined spaces. The hex shape also reduces the amount of arc required to reposition the wrench on the next set of flats. This makes ratchet spanners more cost-effective and useful in more professional applications.

Ratchet spanners have a wider range of uses than square-head sockets. Ratchet spanners can be used for fastening hex nuts, whereas square-head sockets are better suited to large, threaded nuts and bolts. However, they do have a higher price tag and require specialist training. However, they are incredibly useful for a wide range of service tasks.

They can be used to tighten and loosen in tight spaces
These spanners have a unique feature: a ratchet on one end and an extension arm on the other end. These extensions allow users to reach hard-to-reach nuts and bolts. They are available in lengths ranging from half an inch to 20 inches. You can also purchase extensions in one to three-inch increments. These extension arms typically feature knurled sections for better gripping.

When buying a ratchet wrench, choose a size that matches the size of the fastener. The socket should fit snugly in the ratchet head. The ratchet head should have a quick-release button. Once the socket is on the ratchet, turn the socket handle counter-clockwise to tighten the nut, and turn it clockwise to loosen it.

Ratchet spanners can be used on a wide variety of workpieces, including those in tight spaces. However, they should not be used on a workpiece that is too deep for the ratchet head to reach. These tools are also not useful when the workpiece is attached via sliding mechanisms.
