Center Bolt for Steel Plates

Name: Center Bolt for Steel Plates
Brand: YONGYI

Product Introduction Steel plate center bolts are specialized fasteners engineered for automotive sheet metal assembly, crafted from high-strength carbon steel or alloy steel via precision forging and quenching-tempering treatment. Featuring a centered threaded structure and a flat bearing surface, these bolts ensure uniform force distribution during installation, effectively preventing sheet metal deformation or cracking caused by uneven stress. The product surface is available with anti-corrosion treatments such as electro-galvanizing, hot-dip galvanizing or dacromet coating, which significantly enhances its resistance to rust and wear, adapting to the harsh working environment of automobile chassis and body. With high dimensional accuracy and strong compatibility, it can perfectly match with corresponding nuts and washers to achieve reliable fastening effect. Product Application Mainly applied to the fixation of key sheet metal components in automobiles, including the connection of chassis steel plates, the assembly of body frame structural parts, the installation of cab metal plates and the fastening of cargo compartment sheet metal components of commercial vehicles. It is also widely used in the assembly and maintenance of agricultural vehicles, construction machinery and other equipment with sheet metal structures, serving as an indispensable core fastener to ensure the overall structural stability and safety of the vehicle.
