A wrench is a type of tool used for fastening and loosening nuts and bolts by applying torque. A wrench can come in a variety of shapes and sizes depending on the job it's meant to do. However, if you're an all-around fixer-upper, here are five wrenches that you should have in your toolbox:
This type of wrench is the most common type of wrench that you would see on your dad's toolbox. Created for tightening and loosening bolts or nuts, an open-end wrench has a U-shaped opening on both ends in different sizes. An open-end wrench is flat which makes it easier to fit in nuts and bolts within tight or small spaces. Another characteristic that makes an open-end wrench unique is the 15-degree angle of the head from the handle which allows for greater range of movement.
Another type of wrench that you can see in most toolboxes today, a combination wrench is a combination of two tools in one. On one end, you have a wrench and the other is a box-end wrench which looks like a grooved ring. A combination wrench comes in a variety of sizes with each piece having the same size. A combination wrench is a multi-purpose tool that you can use to tighten and loosen bolts as well as gain leverage and a firm grip by using the other end.
If you've ever built furniture, then this wrench is something you're familiar with. An Allen wrench is either a T or L-shaped with hexagonal ends to match the openings of different bolts and screws. This type of wrench is mostly used for piecing together furniture or for small nuts and bolts. An Allen wrench can also come in a variety of sizes and are usually sold in sets.
Otherwise known as a ratchet wrench, socket wrenches have a similar function as a box-end wrench with a detachable socket or a hollow cylinder where the nut or bolt goes in for tightening or loosening. Socket wrenches have a detachable head that you can use for objects of different sizes. It is an efficient tool that can be used in several angles thanks to its rotating sockets.
Perhaps one of the most useful wrenches on this list, an adjustable wrench is a flexible tool that can fit any size of nuts and bolts. Instead of replacing the head like in a socket wrench or finding the right size in your set of open-end wrench, an adjustable wrench simply adapts to the size of the nut or bolt accurately. As awesome as it is, an adjustable wrench tends to slip easily when used with too much force.
