Machinery and Equipment Connections
Long bolts play a crucial role in machinery and equipment, often used to connect major components such as engines, transmission systems, support frames, gearboxes, reducers, clutches, transformers, and more. These components need to withstand significant tensile and shear forces, and long bolts, with their large diameter and length, provide sufficient strength and stability to ensure the normal operation of machinery and equipment.
