| LOCK NUTS | |

Lock nuts are very useful and are used by engineers
and mechanics. The diagram opposite shows a wheel pushed onto a
threaded shaft. Washers are placed on either side of the wheel and a
lock nut is finally threaded in position. This is a highly effective
method of securing a wheels on shafts / axles. |
|
A close look at the lock nut shows that it has a nylon sleeve. As the
nut is tightened, the thread on the shaft / axle cuts into the nylon,
holding it firmly in position. |

|
|
| An alternative is to use two threaded nuts as seen in the drawing above. The second locks the first in position and in this way keeps the wheel firmly in position. | |
