High‑strength serrated locking rings for secure fastening in machinery, automotive, and industrial assemblies. Custom sizes & materials available. Request a quote now!
A serrated locking ring is a precision engineered metal fastening component featuring inward and/or outward serrations (toothed edges) designed to engage mating components securely and resist loosening under vibration and torque. When installed, the serrations dig into the parent material or mate with serrated inserts, creating a reliable locking mechanism for bolts, studs, connectors, or assemblies.
These locking rings are used across industrial, automotive, aerospace, and heavy‑duty machinery applications where secure fastening and anti‑loosening performance are critical.
Our serrated locking rings are optimized for performance, durability, and reliability:
High‑Strength Construction: Made from premium metal alloys such as hardened steel for long service life.
Enhanced Grip Locking: Serrations on inner/outer diameters lock securely with mating parts to prevent rotation or slip.
Wide Compatibility: Ideal for assemblies with bolts, studs, threaded inserts, and lock components.
Anti‑Vibration Stability: Engineered to maintain locking force even in high vibration and dynamic loads.
Easy Installation: Designed for efficient press‑fit or driven installation into housings or components.
Serrated lock rings are used in a range of industrial fastening solutions including:
✔ Automotive assemblies and chassis components
✔ Heavy machinery and equipment fastening points
✔ Aerospace and defense locking hardware
✔ Commercial and industrial engine assemblies
✔ OEM production lines requiring high‑strength lock solutions
These rings are widely referenced with NSN standards and catalog listings, confirming their use in professional industrial supply chains.
