Bolts are typically defined as fasteners that require a nut to secure two or more components together. They are used with pre-drilled holes and are often accompanied by a washer to distribute the load. Bolts are designed for higher load-bearing applications and provide a strong, secure connection. Screws, on the other hand, are fasteners that create their own threads as they are driven into the material. They do not necessarily require a nut and are often used for wood, metal, or plastic assemblies. Screws are generally easier to install but might not offer the same level of strength and security as bolts.

When it comes to car washing, car owners must remember these three taboos, getting it wrong can ruin your car, but many people don’t know that! The first point: the high-pressure water gun should be fan-shaped. High-pressure water guns are essential for car washing, but high-pressure water guns can also damage car paint. Be sure to adjust to the fan-shaped water outlet when using it. The fan-shaped water outlet causes less damage to the car paint and the force-bearing area is small, so it will not damage the car paint!

In fact, regular buffing and waxing can help protect your paint and keep it in good condition. However, there are some things to remember: Correct Techniques: When polishing and waxing your car, it is important to use the correct techniques and tools. Applying too much pressure, using abrasives, or using the incorrect polishing pad can damage the paint. Frequency: While regular buffing and waxing is beneficial, too much frequency can wear away the clear coat over time. Varnish is the protective layer on the paint surface, and over-polishing can cause it to thin over time. It is generally recommended to buff and wax your car a few times a year, or as needed depending on the condition of the paint.

Mistake : take the wheel by “appearance”, ignore the hub parameters. The change of wheel hub style has an immediate effect on the appearance of the vehicle. But if only pay attention to the hub appearance did not pay attention to the hub parameters to match the original car data, it is easy to replace the hub and wing plate, calipers, shock scratch and even can not be loaded. The following important parameters of the wheel hub are related to the loading of the wheel hub, which needs special attention: Hole spacing (PCD) : must be exactly the same with the original car data. Offset: If the offset is not appropriate, the hub is easy to interfere with the shock absorber or wing plate. Center hole (CB/HUB) : If the center hole of the hub is small, it cannot be loaded at all. Size (Size) : the size of the modified hub should match the model. Too big or too small will have loading problems.

One is size: don’t blindly increase the hub. Some people increase the wheel hub to improve the performance of the car. Under the condition that the outer diameter of the tire remains unchanged, the large wheel hub is bound to match the wide and flat tire. The lateral swing of the car is small, and the stability is improved. pass by. However, the flatter the tire, the thinner the thickness, the worse the shock absorption performance, and the greater the sacrifice in terms of comfort. In addition, the tires are easily damaged if there are some roadblocks such as stones. Therefore, the cost of blindly increasing the hub cannot be ignored. Generally speaking, it is most appropriate to increase one or two sizes according to the size of the original wheel hub. Read extra details on jjjwheel.com.
