DIN EN 1665 heavy-duty hexagonal flange bolt is a kind of fastener, mainly composed of hexagonal head, flange plate and screw rod. Heavy-duty hex flange bolts have some unique advantages over regular bolts. First, the flange part has a thinner part that can be slightly deformed to make the connection stronger. Secondly, because the bolt head is small and the flange has a tightening effect, it can be used safely even on softer, non-wear-resistant materials without causing punctures. Additionally, because flange bolts have smaller heads, they can be easily installed into the holes using specialized tools, similar to how hexagon socket head bolts are installed.
