The uses and precautions of double-headed bolts
2025-09-10
Double-ended bolts, also known as double-ended screws or double-ended studs, are used for the fixed connection function of machinery. Double-ended bolts have threads at both ends and a middle shank, which can be thick or thin. They are generally used in mining machinery, bridges, automobiles, motorcycles, boiler steel structures, cranes, large-span steel structures, and large buildings, etc.
They can be used in mechanical seal seats, observation mirrors, reducer frames, and other equipment parts that require frequent disassembly and assembly.
When the thickness difference of the connecting body is large or the bolt length is long, double-ended bolts can provide stable support.
To ensure the connection reliability of double-ended bolts and prevent safety accidents, regular inspections, the use of anti-loosening nuts and high-strength bolts, and other measures should be taken.
Double-ended bolts, with their convenience, adaptability, and safety, are widely used in mining machinery, bridges, automobiles, construction, and other fields, especially in engineering scenarios with high loads and frequent disassembly.
