Wrench Tools

If you own a car, you have seen or you have used a wrench tool. Another name for a wrench is a spanner tool, normally used to allow a mechanical advantage or a grip. Its common role is to fasten bolts or nuts so that they do not keep on spinning. The user must exert slight pressure when using a wrench. You can find different wrench tools styles and each has a unique role.  If you go to the UK or British land, you will have to use the word spanner when you mean wrench, in American English. Both words refer to the same tool. The manufacturers of these devices make chrome-plated tools to prevent rust. Spanners come in different sizes, shapes, and lengths and have other unique characteristics. The very common or ordinary spanners are:

The Open-end wrench or spanner – This is a one-piece wrench that has u-shaped openings. It grips two opposite bolt or nut’s sides. It is usually a two-ended tool and one of its sides has a different sized opening, from the other. Each end aligns at an angle of about fifteen degrees to the longitudinal axis of the handle. This design allows a bigger range of motion by tossing the wrench tool over.

Box end spanner – This is also called the ring wrench and it is a one-piece tool which has an encircled opening. This opening grips the sides of the nut or of the bolt. It is very useful when you want to fasten or unfasten six sided or hexagonal shaped nuts or bolts.  The good thing is that the tool comes in many sizes. This allows the user to use the twelve points or an eight points wrench tools with square shape nuts or bolt heads. This tool has two ends and comes with offset handles to make-work easier.

The combination spanner/wrench – This is a dual ended tool but each end has a different design. Once side looks like a ring end spanner’s ends while the other side looks like an open-end spanner’s ends. The amazing thing is that both the open end and the ring end fit the same size bolt head.

Crowsfoot spanner/wrench – This has many other names including the line wrench, the tube wrench and the flare nut wrench.  You can use it to hold nuts on the tubes’ ends. This tool does not encircle a nut totally like a ring-end wrench would do. It has a slightly narrower opening to fit over the tube. It is normally useful where the nuts are prone to damage, if you use an open-end tool with them.

The adjustable wrench or spanner – This is the shifting spanner in other words.  It features a movable jaw that makes the tool flexible to handle different sized nuts or bolts. This comes in different forms such that you can find a monkey wrench, which has soft jaws and a straight handle. Another type is the adjustable end tool, which is the most popular because of its modern design. The above wrench tools are just a few, compared to the varieties available for you.
