Stainless Steel SS304 316 316L Plain 12 Point Flange Head Metal Bolt 12mm 20mm 50mm

Offering superior corrosion resistance and a clean, professional appearance, this range of 12-point flange bolts is available in a choice of premium stainless steel grades: SS304, SS316, and SS316L. These materials are renowned for their ability to withstand rust and chemical attack, making them ideal for applications where longevity and hygiene are paramount. The bolts feature a plain (natural) finish, showcasing the inherent luster of the stainless steel and providing a smooth, crevice-free surface. The 12-point flange head combines the load-distributing benefits of an integral washer with the high-torque capabilities of a multi-point drive. Available in popular lengths of 12mm, 20mm, and 50mm, these bolts offer a versatile and durable fastening solution.

The excellent corrosion resistance of these stainless steel bolts makes them the go-to choice for harsh and hygienic environments. They are extensively used in marine applications (boat fittings, dock hardware), food processing equipment, and chemical plants where exposure to moisture, salts, and chemicals is constant. SS316 and 316L, with their molybdenum content, are particularly suited for environments with higher chloride exposure, such as coastal areas or pharmaceutical manufacturing. The clean, plain finish is also favored in architectural applications, outdoor furniture, and medical equipment where aesthetics and easy cleaning are required. The compact 12-point head allows for use in tight spaces in these varied assemblies.

The primary advantage is superior, long-term corrosion resistance provided by the 300-series stainless steel, drastically reducing maintenance and replacement costs in corrosive environments. The choice between 304, 316, and 316L allows for precise material selection based on the specific chemical and environmental demands of the application. The 12-point flange head allows for higher clamping torques compared to a hex head of the same size, ensuring a strong, vibration-resistant joint. The plain finish is free from coatings that could chip or wear, ensuring the corrosion resistance is uniform and durable for the life of the fastener.
