Stainless steel Locking washer&Quarter-Turn Retainer, Size 6, Stainless Steel

Lock washers are designed to be tightened to a required torque beneath an ordinary fastener. They exert a spring tension that keeps the fastener from vibrating loose. They are often attached to the nut side of the fastener.
Lock washers are made from such hardened metals as stainless steel, galvanized steel, zinc-plated steel, and silicone bronze.
Lock washer use often involves transportation, such as automotive, aircraft, or marine applications that see persistent vibration.Designed for use with square-neck bolts such as carriage bolts, these washers have teeth that dig into wood and other soft material to prevent rotation. They’re zinc-plated steel for corrosion resistance in wet environments.    

Lock washers are available in two basic types: spring action (or split) washers and tooth washers.
Split lock washers are helical-shaped split rings. When fastened, the two ends exert a spring force on the fastener to create increased friction and resistance to motion. Helical spring lock washers are the most common form of a lock washer and are best suited to applications with smaller loads. High-collar lock washers are a kind of split washer.
Internal tooth lock washers have teeth made to bite into the nut/screw head and surface it contacts. They work best on small screws or screws used in electrical grounding.
External toothlock washers (also called star washers) have teeth made to bite into the bearing surface. An external tooth lock washer is designed to provide stronger holds than internal-tooth washers as the teeth bite into a larger radius and are best suited to large screws.
When working with lock washers, consider that a tooth lock washer can leave scratches on its attaching surfaces. In addition, a tab washer is designed for harsh environments and has a tab that you can bend against the nut or fastener head to hold it in place.
Tip: Lock nuts are nuts designed to resist loosening from vibration or torque and are sometimes used as alternatives to lock washers.
