Hard Lock Industry

Company record

Hard Lock Industry manufactures self‑locking, vibration‑resistant lock nuts engineered for extreme vibration environments. The nuts provide a high rotation resistance and prevent loosening, can secure a screw at its midpoint, are fully reusable, and maintain bolt axial force while being installable with only a wrench. They are applied in railway systems, civil‑engineering projects, towers and pylons, wind‑turbine towers, as well as telephone, radar and power masts. The product line also includes lock bearing nuts, lock set screws and lock pins.
