Product Description

Locking nuts and bolts are fasteners designed to prevent loosening under vibration or shock loads. These products are commonly used in industries such as aerospace, automotive, and heavy machinery, where joint reliability and safety are paramount.


The locking mechanism of these nuts and bolts comes in different forms, including nylon inserts, deformed threads, and prevailing torque designs. The materials used to manufacture these fasteners vary depending on the application requirements. For example, stainless steel and titanium alloys are commonly used in harsh environments where corrosion resistance is critical.

Locking nuts and bolts offer several advantages over standard fasteners, such as improved joint integrity, reduced maintenance costs, and increased safety. Additionally, their use can eliminate the need for lock washers or other secondary fastening methods.
