The bolts of high-strength bolts are not only the tensile strength of the material, but also the mechanical properties of the torque. So after everyone talked about high-strength bolts, we can talk about bolts below. What are the differences between ordinary bolts and high-strength bolts? How should everyone treat high-strength bolts correctly, and how to reflect the high-strength of bolts, everyone can give a general detailed explanation, hoping to bring beneficial help to friends in front of the monitor. Many consumers can't tell the difference between high-strength bolts and ordinary bolts. In fact, they can be easily identified as long as they grasp their characteristics such as models and specifications. In short, high-strength bolts are special-made bolts with high strength and high fatigue resistance that are often used in special mechanical equipment or construction projects. Of course, generally high-strength nuts are used with high-strength bolts to achieve stronger expected results. You generally see in the market that many bolts with M-heads are ordinary bolts, not high-strength bolts. The correction side of ordinary hexagonal head bolts is the following format file M30. Among them, M30 marks the thread specification, that is, The inner diameter of the pipe thread is 30mm, the grade 10 marks the performance parameter grade of the bolt, and tZn is the surface treatment method. The above is the difference between high-strength bolts and ordinary bolts brought to you by Xiaobian. I hope it can help you.
