High Tension Bolt 8.8

The steel construction joint is a critical part and determines the overall strength of the structure. If you use a bolt, the strength depends on the quality specifications. In building planning referring to SNI there are two types of high quality bolts namely A325 and A490. For bridges that refer to the PU Bridge Bolt Installation Guidelines (2015), the choice is more varied. There is a grade 8.8 quality equivalent to A325; and grade 10.9 & F10T equivalent to A490. Equivalent in a sense, strong melting and strong pull, the same.
