High-quality Flange Button Head Screw supplied by Valaki Enterprise, Nashik — ISO certified, bulk supply to Nashik, Pune & Mumbai.
The Flange Button Head Screw combines a low-profile button head with a wide integrated flange base that significantly increases the bearing surface area. This design eliminates the need for a separate washer while distributing clamping loads evenly across the mating surface, reducing the risk of surface damage or deformation.
Engineered for high-vibration environments, these screws are widely used in automotive assemblies, sheet metal fabrication, plastic panels, and light-structure brackets. Available in mild steel with zinc plating and stainless steel grades, offering excellent corrosion resistance across diverse application conditions.
