Packed in a sturdy three hundred count box, these heavy split helical spring lock washers deliver serious anti vibration grip for bolting down tough assemblies. You will find them locking nuts tight on industrial trailers, wood framing projects, metal fabrication jigs, and heavy equipment maintenance builds that see constant torque and shakeout.

✅ Nominal outer diameter measures exactly 1-1/8 inch
✅ Cut from cold formed carbon steel for solid tensile strength

✅ Rated Rockwell C38 C46 hardness handles high clamp loads
✅ Compliant with ASME B18.21.1 standards for consistent fit

💡 How do thick split lock rings keep hex nuts from spinning loose on vibrating equipment?
The twisting action applies steady upward pressure under the bolt head so threaded connections stay locked tight through rough work. These rings do three main jobs:
- The coiled shape acts like a spring wedge that fights rotational slippage during shock loading
- Heavy cut steel keeps clamping force consistent across temperature swings and frame flex
- Corrosion resistant plating blocks moisture and road grime while letting tools bite down hard
