Introduction to common bolt specifications
First, let's introduce the commonly used bolt specifications. M16*65, M20*80, M24*100 are very common. In terms of grade, there are 4.8, 8.8, and 10.9. 4.8 is ordinary strength, 8.8 and 10.9 are high strength. In terms of material, there are two options: stainless steel and iron. Stainless steel bolts are generally used in occasions that require rust prevention, while iron bolts are mostly used for ordinary mechanical connections. Remember these specifications, and you won't be afraid when looking for screws in the future!
Characteristics and applications of high-strength bolts
High-strength bolts are the stars in the engineering industry, mainly used in steel structure engineering. It uses friction-type high-strength bolts to connect, and the force is transmitted by the friction force on the surface of the steel plate, with strong bearing capacity.
Common high-strength bolt specifications include M8, M10, M12, etc., and the grades are divided into 8.8, 10.9, and 12.9. Pay attention to some details during installation. The installation must be completed on the same day, and the insertion direction must be neat and consistent. The installation of high-strength bolts also requires the use of special tool bags to prevent falling from high altitudes.
There are so many uses and features of high-strength bolts! They not only have strong load-bearing capacity, but are also easy to install and can be operated after simple training. During the transportation of steel structures, high-strength bolts can also effectively reduce maintenance workload. Isn't it very practical?
