Stainless steel hex flange nut is an integrated threaded fastener combining a hexagonal nut body and a circular flange at the bottom. It is used with bolts to spread clamping force onto the surface of the connected component during tightening.
Made of 304 or 316 stainless steel, this nut features excellent rust and corrosion resistance, adapting well to outdoor, humid and corrosive working environments. The one-piece flange structure expands the bearing area, disperses fastening pressure and avoids the need for extra washers. Many versions come with anti-slip serrations on the flange face to strengthen locking performance and prevent loosening under vibration. It simplifies assembly procedures and is widely applied in machinery, vehicle equipment, frames and pipeline systems.
