Function:
Using lift form inclination to improve rub bond stress can reach better fixed effect of the expansion screw anchor. Expansion bolt type specification45, 50, 60, 70, 80, expansion bolts grade and its materials can be mainly classified as austenite A1, A2, A4, martensite and ferrite C1, C2, C4. For example, A2-70, "--" represents bolt material and 70 represents strength grade. The following is the full expansion bolt specification table. Bolt materials commonly are Q215, Q235, 25 and 45 steel. For important or special purpose of threaded connection15Cr, 20Cr, 40Cr, 15MnVB, 30CrMrSi, alloy steel with high mechanical properties would be good choice.
