The phrase “what holds a car wheel in place?” refers to the lug nuts and bolts that are used to secure the wheel to the axle and hub of a car. Lug nuts are typically made of steel or aluminum and have a tapered shape that allows them to be tightened against the wheel and hub. Bolts are typically made of steel and have a threaded end that screws into the lug nuts. When the lug nuts are tightened, they pull the wheel against the hub and prevent it from coming loose.
It is important to ensure that the lug nuts are properly tightened to the correct torque specifications. If the lug nuts are not tight enough, the wheel can come loose and cause an accident. If the lug nuts are overtightened, they can damage the wheel or the hub. It is also important to check the lug nuts regularly for signs of wear or damage.
