This silo bolt is designed for connecting metal sheet structures in bulk material storage facilities such as grain silos, cement tanks, and feed bins. The bolt body is made of carbon steel with a zinc-plated finish to resist corrosion in industrial environments. It features a colorful plastic cap on the head, which prevents dust, moisture, and contaminants from entering the threaded area, reducing the risk of rust and product contamination.
Some models include a rubber washer to enhance sealing performance, making them suitable for applications requiring leak prevention. The caps are available in multiple colors (red, yellow, blue, black), allowing for visual identification and classification during installation or maintenance. The bolt can be used with hex nuts for secure fastening and is reusable after disassembly. Commonly used in prefabricated steel silos, storage hoppers, conveyor systems, and industrial buildings where sheet metal joints require reliable sealing.
