BSM Blank Nut With Chain

BSM blank nuts with chain are designed to cap and protect hygienic BSM union ends when they are not in use. These components help maintain cleanliness and system integrity by sealing open union connections, preventing the ingress of dust, debris, moisture, or contaminants. They are commonly used in sanitary processing environments where unused or temporarily disconnected unions must remain hygienically protected between operations.

The integrated stainless steel chain is a practical feature that helps prevent loss of the blank nut during maintenance or cleaning activities. By keeping the cap attached to nearby pipework or equipment, the chain ensures the blank nut remains readily accessible and can be quickly refitted when required. This is particularly valuable in busy processing areas where components are frequently removed and replaced during wash-downs, inspections, or changeovers.

Manufactured from Grade 316 stainless steel, BSM blank nuts with chain offer excellent corrosion resistance and durability in demanding hygienic environments. Grade 316 contains molybdenum, providing superior resistance to chlorides, cleaning chemicals, and aggressive wash-down conditions compared with standard stainless grades. This makes these blank nuts well suited for food and beverage processing, dairy operations, brewing, pharmaceutical manufacturing, and other applications involving frequent exposure to moisture, steam, and sanitising agents.

The smooth stainless steel surface is easy to clean and resistant to product build-up, supporting compliance with hygiene and food safety requirements. When fitted correctly, the blank nut provides a secure protective seal that safeguards the union face and threads from damage or contamination while the connection is not in service.

BSM blank nuts with chain are available in a range of sizes to suit standard BSM union dimensions. To ensure correct fit and effective protection, select the blank nut size that matches your BSM union size.
