Fasteners used in automobiles are nuts and bolts. Nuts secure the attachment of bolts and screws to a given surface, and they use interior female threading. Bolts are normally threaded with pins and rods; they are characterized by heads and are employed for constructing the wheel.

You should ensure that there is a higher level of tension holding together the head bolts in the critical areas than the fasteners’ load capacity. The joints need to be bound with absolute tightness; insufficient joint tension will result in a combination of force and vibration that serves only to loosen the bolt. On the other hand, an excess level of tension could damage the fastener. Hence, it is important to strike the right balance.
