- Helical spring lock washers are the most common washers used to prevent components from loosening.
- When compressed, the lock washer will twist and flatten. This prevents loosening.
- A4 stainless steel is functionally equivalent to 316 grade and is also known as "marine grade".
- Stainless steel significantly improves resistance to tarnishing or corrosion.
