WRENCHES 

A WRENCH DOESN'T LOOK LIKE A TROUBLEMAKER

Wrenches seem simple and safe. Yet why do they cause so many accidents? 

WHY WRENCHES CAUSE ACCIDENTS

The answer is that either the correct type of wrench isn't used or improper use of the wrench causes it to slip. The result can range from mashed knuckles to a serious fall. Slipping is caused mostly by using a wrench that is slightly oversized for the nut. If the wrench is properly sized, it applies equal pressure to the faces of the nut. But if the wrench is just a bit oversized, the pressure is applied to the corners of the nut where the jaws touch. And the wrench slips. Eventually the jaws of an improperly used wrench can become weakened or sprung. Then the wrench won't even fit the right size head. Some persons try to use shims to compensate for the wrong size wrench, but this isn't satisfactory either. 

Another reason why your wrench slips is that it isn't fully seated on the nut or bolt. This usually happens when the nut to be tightened is hard to reach. This situation calls for an offset or socket wrench.  Lt may seem like a lot of trouble to get one, but it's worth it. Always pull on a wrench and adjust your stance to prevent a fall if something should suddenly slip. 

FIXED JAW WRENCHES ARE PREFERABLE TO ADJUSTABLE WRENCHES

You should use a fixed jaw wrench that fits rather than an adjustable wrench. Box or socket wrenches are even less likely to slip. Pliers are no substitute for a wrench. 

Don't misunderstand, however. An adjustable wrench is a good tool when properly used. Always place this wrench so that the pull on the nut comes from the solid jaw and the push from the adjustable jaw.  

CHEATERS

A common mistake is using apiece of pipe or "cheater" on the handle of a small wrench to increase the leverage. This can place more stress on the wrench than it is designed to take, causing it to break or the pipe itself to slip off. In either case, the person using it can have an accident. Imagine what would happen to you if you were standing on a ladder when the pipe gave way. Don't use a wrench as a hammer or a pry bar. Lt won't do you or the wrench any good. 

FROZEN NUT

To free a frozen nut or bolt, apply penetrating oil and use a striking face box wrench.  

TAKING PROPER CARE OF YOUR WRENCHES WILL HELP MAKE YOUR WORK EASIER

No, a wrench doesn't look like a troublemaker and it doesn't have to be one, if you use it right. Keep it clean and in good repair and bear in mind the tips we have just pointed out.
