1. What are hex flange bolt?
Hexagon flange bolt is a fastener composed of hexagonal head, flange and screw.
2. What are the performance grades of hexagonal flange bolts?
Grade 8.8/10.9/12.9
3. What are the advantages of hexagonal flange bolts?
The common bolt head is very thick, so it is difficult to deform. If it vibrates after being fastened, it needs to be tightened again. The flange has a thin part, which can be slightly deformed and locked more firmly. That is, if you go up into the hole, ordinary bolts can't use tools. The head of flange bolts is small, and the flange below also plays a fastening role, but special tools can be used to go up into the hole, which is about the same as the principle of hexagonal bolts. Then there is the flat pad at the top of the flange, which is safer on the softer, non-wear resistant material and will not cause perforation.
