(Last Updated On: April 27, 2018)

An impact lug wrench is a kind of socket wrench designed specifically to clear out lug nuts. A lug nut can be a nut having a rounded base, popular to install wheels on automobiles. Lug wrenches will also be called wheel wrenches, wheel nut wrenches, or wheel braces. The term “tire iron” is additionally used, but a real tire iron can be a lever for separating tube tires from your wheel rim. There are three major sorts of lug wrenches.

Socket Wrench: This is simply a socket mounted on a protracted, angled handle. Most cars have such type of wrench, filled with either the abdominal fat or even the jack. Sometimes such a wrench could have a tapered prybar-like end for removing hubcaps. Wrench designs consist of manufacturer to manufacturer with respect to the nut size, nut torque, and safe-keeping available. This has made older OEM wrenches very collectable the type of restoring antique cars to original condition.

Four Way: These lug wrenches use two metal rods welded together for making an “X” shape. Some four ways can have a socket each end, or three sockets and another end using a prybar for removing hubcaps. Aftermarket wrenches are nearly always bought from this method.

Center Lock Wheel Nut Wrench: Instead of using several small nuts, some custom high-performance wheels employ a single large locking center nut. Wheels created for drag racing come having a socket to use through an impact wrench while wheels created for street use could have a wrench using a leveraging wrench allowing drivers to put on the huge degrees of torque was required to tighten the nut securely. For example, the wheel nuts on latest Porsche GT3 requires over 360lb-ft of torque yet light finger pressure is sufficient tighten the nut while using included wrench.

There are six common sizes of lug nuts on passenger cars and light-weight trucks: 17mm, 19mm, 21mm, 13/16-inch, 7/8 inch, and one inch. Four-ways are roughly split into car sizes (17mm-21mm) and truck sizes (21mm-1 inch.)

Some cars have “Locking” lug nuts. These employ an engineered head that cannot be removed with common tools. Cars typically consist of an adapter nut that suits inside lug wrench, allowing it to turn the lock nut. Some cars utilize a similar system to lock the hubcap within the lug nuts. These could have a different wrench, typically set with the chubby tummy.

Lug nuts really should be screwed on employing a star pattern, moving towards the nut furthest on the last one that had been tightened. Alloy wheels is usually slightly misaligned when tightened personally that may cause vibrations at high speeds. This vibration may be remedied by tightening the nuts to spec utilizing a torque wrench.

Some older vehicles include tin-capped nuts. These caps can function loose as they age, lowering the nut’s exterior size. For example, a 21mm lug nut without it cap is all about 20mm. Using a lug wrench on these could round over bolt. The best option would be to make use of a socket together with the correct fit or make use of a loose cap as a possible adapter about the wrench.
