IFI 538 heavy-duty hex flange face bolt is a fastener produced in accordance with IFI (Industrial Fastener Institute, Industrial Fastener Association) standard 538-1982. IFI 538 heavy-duty hex flange face bolts have a larger hex head and flange face design, which increases the contact area between the bolt and the connection, thereby improving the stability and load-bearing capacity of the connection. At the same time, the flange surface design can also play an anti-loosening and anti-slip role.
