Keep fasteners secure in challenging conditions with the Hillman 0.19 in. diameter zinc-plated steel split lock washers — a dependable 100-pack designed for durability and ease of use. Engineered to resist vibration and preload loosening, these washers are a smart addition to any mechanical, furniture, automotive, or outdoor project.
What makes a split lock washer effective
A split lock washer uses a carefully formed gap that creates spring tension against the bolt and the nut. As vibrations or dynamic loads occur, the downward bite of the washer increases friction and resists rotation, helping fasteners stay tight without continual retightening. The result is a more reliable, long-lasting connection in assemblies that see movement, impacts, or thermal cycling.
Why Hillman zinc-plated steel stands out
Made from sturdy steel and finished with corrosion-resistant zinc plating, these washers offer reliable performance in both indoor and outdoor settings. The zinc coating helps guard against rust and wear, making them suitable for projects where moisture or humidity may be a factor. The 0.19 in. diameter provides a compact yet effective option for lightweight fasteners, while the boxed packaging keeps the entire 100-count set organized and ready for use.

- Ensure fasteners are clean and free of debris; a light dab of lubricant may be used on threads to facilitate assembly, but avoid over-lubricating as it can reduce friction.
- For high-vibration or outdoor applications, consider using additional locking methods (e.g., thread-locking compounds) in conjunction with the washer for added security.
