Stainless steel Hexagon Flange Bolts

Product  introduction

Stainless steel flange bolts are made of high-quality austenitic stainless steel materials such as 304 and 316. With excellent corrosion resistance, they can work stably for a long time in harsh environments like humidity, acid, and alkali, effectively preventing rust and ensuring long-lasting and firm flange connections.​

Through precise forging and heat treatment processes, the bolts have good strength and toughness, with a tensile strength of 520MPa – 780MPa. They can withstand significant pressure and tension, preventing loosening and breakage. The products come in a wide range of specifications, with thread sizes ranging from M6 to M48 and lengths from 20mm to 300mm, suitable for flanges of different sizes. The surface is smooth and can meet the requirements of general environments without additional treatment. Polishing, passivation, and other treatments can also be carried out as needed to further enhance aesthetics and protection performance.​

Widely used in industries with high corrosion resistance requirements, such as food and beverage, pharmaceutical and chemical, shipbuilding, and marine engineering, our products are manufactured and tested in strict accordance with domestic and international standards such as GB, ISO, and ASTM. We provide comprehensive pre-sales selection guidance and after-sales technical support, offering reliable fastening solutions for customers.
