Heavy duty split ring lock washers for secure fastening
✔️ 18-8 stainless steel black oxide finish pack of 100

Pack of one hundred number eight split ring lock washers keeps nuts and bolts tight when things shake loose. These star-shaped metal pieces sit flat against surfaces and apply constant spring tension to hardware. They prove pretty handy for truck suspensions, trailer rigs, deck joists, and workshop gear that takes a beating.

✅ 18-8 grade stainless steel resists rust and corrosion
✅ Black oxide coating adds scratch protection and smooth threading
✅ Inner diameter fits standard number eight hex nuts securely
✅ Spiral cut design locks out slippage and reduces maintenance downtime

💡 What causes fasteners to loosen repeatedly on moving equipment?
The problem usually comes down to friction loss and harmonic shaking over time. A proper lock washer system solves this by maintaining steady clamping force. Here is how the setup works for lasting reliability:
- spiral gap compresses against fastener head to block backward spinning
- hardened alloy metal handles extreme torque without flattening out
- surface coating reduces galling and stops moisture from eating through threads
