What are the requirements for the nuts used with anchor bolts?
Thread Content
For the anchor bolts specified in the equipment design, whose material is Q235 and Q345, what should be the corresponding nuts? What are the standards for material, precision, and performance?
Carbon steel will do! The grade cannot be higher than that of the bolt! The range of choices is very limited!
The stress on the Q345 bolts is 170; since the nuts used are of the Q245 type (with a stress of 147), will there be no problems?
No! Nuts generally have one level lower strength than bolts!
Thank you all. I always think that nuts should match bolts, and bolts made of different materials should be paired with nuts made of different materials as well
