Compared with ordinary bolts, hexagon flange bolts have a larger ratio of support area to stress area, higher preload, better relaxation performance, and high precision and durability of decoration. The hexagon flange bolt head is small with holes, and the slotted bolt can be locked more firmly in case of slight deformation; The flange plate can be divided into flat bottom and toothed shape according to the needs of the industry, and the latter can play a more tightening role.
