3. [Stainless Steel, brass and plastic]

1. Castle Nut- hex nut with castle like section on one side, used with a split/ cotter pin and bolt with pre-drilled hole.

2. Nut is attached and the pin passed through the castle like notches into the hole within the bolt which prevents the nut from turning, can withstand a lot of vibration and movement.

3. [Stainless Steel, Steel, brass, aluminium and plastic]

1. Split Spring Washer- circular disc (rectangle or square profile) which is split, with one end slightly raised.

2. Used with nuts and bolts to aid in tightening and the split applies tension to prevent fasteners e.g. nuts from loosening.

3. [Stainless or carbon steel, brass, copper]

1. Plain Washer- thin circular metal disc (can be square)

2. Prevents the surface of an object getting damaged when a nut is tightened upon it by distributing the load of the fastener
