Tamper-Proof Security Break-Away Nuts

Break-Away nuts are designed to prevent unauthorized removal and secure access to equipment and facilities. No special tool is required. Break- Away nuts are installed using a standard wrench. They are used extensively in correctional institutions, hospitals, schools, public places, and retail stores to secure a variety of products.

Break-Away nuts are suitable for applications where removal of a fixture is not intended and where prevention of tampering is important. Manufactured from ZAMAK 5 zinc alloy and 304 stainless steel. Stainless steel offers greater corrosion resistance and high-strength properties compared to zinc alloy. The nuts are tapped to standard bolt dimensions and are also available tapped oversize for hot dip galvanized fasteners.

Break-Away Nuts are a Non-Removable Security Solution
