Open ended spanners are the most common types of spanners used to fix a glitch. They may be single or double ended and have the heads offset around 15 degrees away from the run of the shaft. Such an orientation of the open ended or ‘C’ spanner allows easy functionality of the tool in confined spaces.

Here are few specifications you should keep in mind to properly use the double open ended spanners:

• A double ended spanner should fit the nut perfectly, otherwise you may end up hurting yourselves and damaging the tool. Too loose or too tight grip is of no use.
• If the nut is too stubborn to move then use penetrating oil and let it seep. You can use the same technique for rusted nails but make sure to wire brush them first.
• If you don’t want to end up with grazed knuckles, then ensure that your hand has a clear area of movement while using the spanner. If the nut is very tight, then sudden release may cause you injury if there is no room for your hand.
• In case of working with chrome surfaces such as faucets and door knobs, use bits of leather to protect the metal from the metal jaws. As far as possible, try abstaining from using serrated jaws.
