High-quality Button Head Flange Bolt supplied by Valaki Enterprise, Nashik — ISO certified, bulk supply to Nashik, Pune & Mumbai.
Button Head Flange Bolt combines the low-profile button head with an integrated washer flange at the base that distributes clamping load over a larger area. This eliminates the need for a separate washer and reduces surface damage by spreading stress more evenly across the mating surface.
Available with serrated flange options for superior vibration resistance, these bolts are ideal for sheet metal assemblies, plastic panels, automotive body components, and any application requiring a secure joint with anti-loosening characteristics. The zinc-plated mild steel construction provides good corrosion protection for indoor and light outdoor use.
