Steel Gr4.8 Galvanized Flange head bolt
Flange bolts are composed of hexagonal heads and flanges. The "ratio of supporting area to stress area" is larger than that of ordinary bolts. Therefore, this type of bolt can withstand higher pre-tightening force and has better anti-loosening performance, so it is widely used. Used in automobile engines, heavy machinery and other products.
