High-quality Hex Bolt – Standard supplied by Valaki Enterprise, Nashik — ISO certified, bulk supply to Nashik, Pune & Mumbai.
Standard hexagonal head bolts are among the most widely used fasteners in structural steel, general machinery, and civil construction. The six-sided head provides a large bearing surface and allows tightening with a standard spanner or socket wrench, making them easy to install and remove in most access conditions. Available in both full thread (ISO 4017 / DIN 933) and partial thread (ISO 4014 / DIN 931) configurations, they suit a broad range of clamping applications. Manufactured from mild steel and finished with zinc plating for corrosion protection, these bolts deliver reliable performance in indoor and sheltered outdoor environments. Custom lengths, special grades, and hot-dip galvanised finishes are available on request for project-specific requirements.
