Lock Nuts

Lock nuts are designed to provide secure fastening with added resistance to loosening under vibration and movement. Commonly used in mechanical, automotive and structural applications, these nuts incorporate a locking feature to maintain a firm connection over time. Manufactured in zinc plated steel, A2 and A4 stainless steel, and brass, they offer durability and corrosion resistance for both internal and external environments.

Available in commonly used metric sizes and thread types, these nuts ensure accurate fit, secure locking performance and consistent reliability across general engineering, maintenance and assembly applications.
