coating on the handle, most are left as plain steel.
Using an adjustable wrench is fairly simple; there are two parallel flat metal jaws, one is fixed and the other is adjustable by turning a screw that can be turned using the knurled or ridged edges of the threads.
The important idiom to remember when using an adjustable wrench is “righty tighty, lefty loosy” which is basically an easy way to remember that almost all fasteners will go forward (or tighten or go in) if you turn them to the right (clockwise) and reverse (or loosen or come out) if you turn it to the left (counterclockwise).
However, getting the most out of this simple tool take some effort. Most of the fasteners you will be turning with an adjustable wrench will not be easily accessible from all sides, this means that the wrench will have to be removed and repositioned after each swing of the handle, which only turns the handle a fraction of one full revolution. The adjustab le wrench’s angled handle can assist with this, allowing you to get a swing of the handle turn each time. In a tight space the wrench can be flipped so that the angle of the handle allows it to fit around an obstruction on one side of the other. With all of this removal and readjustment, however, there is a high probability that the jaw will become misadjusted, therefore it is very important to ensure that the jaws are tight around the fastener at every turn. If they become loose and you still turn the wrench, the bolt can become “rounded over” meaning that the sharp angled corners of the nut or bolt become blunted and eventually will not allow the wrench to grab onto them to rotate the screw. This makes it very difficult to turn the nut or bolt. If you come across a fastener that will not turn with the wrench, or where it is impossible to use with the wrench in its proper position (i. e. with the jaws parallel and in the same plane as the fastener) do not attempt to use it to turn the fastener, it could cause damage to the fastener or the nut and possibly cause injury. There are several other more specialized tools and techniques that can be used on stubborn or difficult to access fasteners and I will address these in a future post.
However, if access is not an issue with the fastener, there is a right and a wrong way to turn the wrench to minimize wear to the adjustment mechanism. If you turn the wrench with the movable jaw towards the direction you’re turning the wrench it will put less strain on the movable jaw and protect the mechanism. Another thing to keep in mind is to try to keep dirt and debris out of the adjustment mechanism, it is good to keep the mechanism as tight as possible, leaving very little “play” or space between the teeth in the underside of the movable jaw, and the screw, but if too much debris gets in, the jaw can become extremely difficult to adjust, making the tool hard to use. To alleviate problems with the adjustment mechanism there is a small screw on the edge of the wrench that will make the mechanism looser or tighter by moving the adjustment mechanism.
screw is the flat-head screw directly above the word "China."Some simple lubricating oil available at any reputable hardware store or home center can also help keep the mechanism running smoothly.
Like hammers, many folks have adjustable wrenches laying around in attics or garages that may have belonged to a grandparent or aunt or uncle. Maybe a handy relative has one that they will let you have. It’s not very important to have a brand new wrench or a top quality one; it’s a very simple tool that is easy to use. If you are buying a new one, top quality adjustable wrenches can cost up to 30 dollars or more, which is quite a bit for a tool that may only be used a few times a year. If you head out to a hardware store or home center, simply look for the cheapest wrench that feels solid. A good way to check if an adjustable wrench is well-made is to wiggle the adjustable jaw, on a well-made wrench the jaw should not wiggle more than 1/16th of an inch in either direction.
As far as safety goes, make sure that you follow all of the usage instructions laid out earlier in the post. In addition, make sure that you have enough clearance to safely swing the handle of the wrench when turning a fastener and that you make sure that your fingers are clear of any obstructions when you turn the wrench so you don’t whack your hand. Also, make sure that the fastener you are turning is in good condition and has relatively defined corners so that the jaws can grip it tightly. Make sure that the jaws are very tight to the sides of the fastener when turning as mentioned earlier in this post. And finally make sure that you don’t try to use it on a fastener that is too big for the wrench or is not accessible to the jaws.
And finally, wearing gloves and safety glasses is, as with any project using tools, a good idea.
