GB 5789 heavy Stainless Steel Flange Bolts are usually made of high-strength materials such as low-carbon alloy steel or medium-carbon steel, and are heat-treated to improve their strength and durability. GB 5789 Stainless Steel Flange Bolts have the characteristics of high tensile strength, compression resistance, torsion resistance, and shear resistance, and can withstand high tightening force and pressure. Depending on the position of the flange bolt, the size requirements of the flange are also different. In addition, the flange can be flat or toothed. The toothed flange has an anti-slip effect. Its unique flange surface design increases the support force, allowing the bolt to disperse more pressure when tightening, and improves the reliability of the connection. GB 5789 heavy Stainless Steel Flange Bolts are widely used in the fastening of various mechanical equipment and products, including but not limited to automobile engines, heavy machinery, aerospace and other fields. Its excellent performance and reliable connection quality make it the preferred fastener in many industrial occasions. In order to meet the need for locking after installation, some bolts are also designed with holes in the rod to prevent the bolts from loosening during vibration.
