High Strength Galvanized Hex Flange Bolts For Industrial Machinery

High Strength Galvanized Hex Flange Bolts For Industrial Machinery are widely adopted connecting fasteners for heavy-duty industrial assembly, covering carbon steel base materials with 4.8, 8.8, 10.9 and 12.9 mechanical property classes. The integrated hexagonal flange design eliminates the need for separate gaskets, which cuts assembly steps and improves fitting tightness. Multiple surface treatments including zinc plating, color galvanization and black oxide are available to match different anti-corrosion standards. Ningbo Gangtong Zheli Fastener Co., Ltd strictly implements ISO 898 mechanical testing standards to guarantee consistent tensile performance of all finished bolts.

Core Advantages & Product Parameter Classification

High Strength Galvanized Hex Flange Bolts For Industrial Machinery adopt hot forging and integral heat treatment processes recognized by global machinery industry standards. The flange tooth design of partial specifications increases friction resistance, effectively avoiding loosening under long-term vibration working conditions. Full size stock range from M6 to M12 covers mainstream industrial assembly demands, and all raw materials are sourced from certified domestic steel mills with complete material inspection reports.

This product series supplies four standard strength grades including 4.8, 8.8, 10.9 and 12.9, each grade matches fixed tensile strength standards specified by ISO 898. Multiple surface finishes including silver zinc, color zinc and black oxide can be freely selected according to client site environment demands, and each surface craft undergoes 48-hour neutral salt spray testing before delivery to verify anti-rust performance.
