Structural Nut Bolt

A structural nut bolt is a high-strength fastener used to join heavy steel members like beams, columns, and rafters. City Steel supplies high-tensile structural nut bolt sets that carry the heavy loads of a factory frame without stretching or failing, keeping your building stable for over 20 years. You get certified ASTM A325 or Grade 8.8 bolts with hot-dip galvanized coating to stop rust in humid environments. Every set comes with a matching heavy hex nut and hardened washer to ensure the joint meets international safety standards. These fasteners provide a secure friction connection that prevents the steel plates from moving under wind or crane loads. These fasteners are used for PEB warehouses, industrial sheds, and multi-storey buildings across Bangladesh. Whether you need standard sizes or custom lengths, we provide project-ready supply for your construction site.
