High Strength Galvanized Hexagonal Bolts

Steel structures, bridges and industrial engineering projects require reliable connecting fasteners. High Strength Galvanized Hexagonal Bolts undergo strict heat treatment to achieve stable tensile capacity, and customers can select matched anti-corrosion surface treatments according to actual service environments. Ningbo Gangtong Zheli Fastener Co., Ltd. implements complete raw material screening and finished product testing procedures to guarantee consistent mechanical performance of each batch of fasteners.

Material & Structural Advantages

Carbon steel is adopted as raw material, and the optimized hexagonal head structure brings larger bearing area and uniform force distribution during installation. Precise rolling thread ensures tight assembly and avoids loosening under long-term vibration. Our testing laboratory carries out tension and hardness tests to verify reliability of High Strength Galvanized Hexagonal Bolts for heavy load applications.

Specification Support & Custom Service

We can supply a rich selection of dimensions covering mainstream sizes favored by global hardware purchasers. Besides standard specifications, customized dimensions and alternative surface treatments are available to satisfy diversified project requirements. Ningbo Gangtong Zheli Fastener Co., Ltd. provides free samples for global wholesalers to inspect High Strength Galvanized Hexagonal Bolts before placing formal orders.
