When a nut or bolt is extremely tight, a lubricant is used so that the teeth in the ratchet head are not damaged.
<h3>What is a lubricant?</h3>
A lubricant refers to the oil that is applied on the metal parts of objects to prevent rusting or damage. A good ratchet is often identified by the number of teeth it has and since its parts are metallic in nature, it is vital that they are regularly lubricated to keep them in shape.
Sometimes, the ratchet can also be degreased during maintenance. The problem that most ratchets tend to have stem from torquing excessively.
