High-quality Hex Flange Bolt – Standard supplied by Valaki Enterprise, Nashik — ISO certified, bulk supply to Nashik, Pune & Mumbai.
Hex flange bolts feature an integrated circular flange beneath the hexagonal head that acts like a built-in washer. This flange distributes the clamping load over a larger bearing area, reducing surface stress and preventing bolt pull-through in thin sheet metal and softer materials. The larger contact area also reduces the risk of loosening under dynamic loads. These bolts eliminate the need for a separate flat washer, saving assembly time and reducing part count. Commonly used in automotive body panels, HVAC ductwork, electrical enclosures, and general sheet metal fabrication. Available in zinc plated and stainless steel finishes for different environmental requirements.
