The wheel bolts are important to secure the wheels. They go through the rims, directly thread into the hub assembly, locking everything in place. It is necessary to keep the wheel bolts working well. Since most of them are made of steel, they may be rusted or corrode by oxidation overtimes. If a wheel bolt breaks due to corrosion, it may gradually loosen. As the bolt loosen enough, the wheels can fall off suddenly, which is one of the most frightening things that can happen to you.
To protect wheel bolts from corrosion-related failure, manufacturing companies often treat their bolts during production. The most common coating ways are Dacromet, Electroplating, Anodizing, and Galvanized. How the wheel bolts are coated is a critical factor in wheel bolts’ safety. So, knowing which is better for wheel bolts’ corrosion resistance helps you make the right decision. Here are two of the best corrosion protection treatments for wheel bolts.
Dacromet-coating Wheel Bolts
The Dacromet-coating wheel bolts are considered to be one of the best corrosion-resistance bolts. This type of coating gives salt spray resistances exceeding 500 hours, which makes it ideal for fasteners in the automobile industry. Most importantly, Dacromet coating does not induce Hydrogen Embrittlement, which means that high tensile components like wheel bolts and lug nuts can be safely coated.
In addition, the Dacromet-coating layer has a heat resistance temperature of above 300 ° C. At 250 ° C, the layer perform well continuously for a long time. The Dacromet treatment fluid can penetrate into the tight joint of the workpiece to form a rust-proof coating so that it can improve the rust prevention ability inside and outside. Since wheel bolts are connecting parts which lock different components in place, Dacromet-coating is effective to avoid any potential rust in the link points.
Electroplating Wheel Bolts
If you’re looking for a set of good rust-proof wheel bolts, apart from the Dacromet-coating ones, the Electroplating wheel bolts are another option. Electroplating is an immersion wet paint finishing process that uses electrical current to deposit paint on a metal surface. It is useful to protect your wheel bolts from corrosion. Every part of the surface is evenly coated with the paint, nowhere is missing. This improves the appearance of wheel bolts, especially if it’s essential to match a specific color and coat uniformly. Moreover, it also behaves greatly to stand up to extreme environments such as water, sunlight, chemicals, etc. It is used worldwide to achieve high-quality corrosion resistance for wheel bolts at a level of high efficiency and environmental compliance.
