※ Characteristics :
Spring washers are locking elements that are used as a simple screw lock to prevent loosening. They are optimally mounted between the screw head and a nut as well as a washer. The bent shape creates a certain pre-tension on the connection, which absorbs vibrations and prevents it from loosening on its own.
The function of the spring washer is that after the nut is tightened, the spring washer gives the nut an elastic force and tightens the nut, making it difficult to fall off. The basic function of the spring is to give a force to the nut after the nut is tightened, which increases the friction between the nut and the screw.
Flat brake pads are generally not used when spring pads are used (unless you want to protect the surfaces of fasteners and mounting surfaces).
A2 stainless steel is commonly referred to as 304 or 18/8 because it contains 18% chromium and 8% nickel. A2 is an austenitic stainless steel and almost non-magnetic, but it easily sticks to a magnet due to the cold forming process. A2-70 is the most commonly used grade, the 70 stands for a tensile strength of 700 N / mm2.
A2 is suitable for a variety of uses in many different industries such as the automotive industry in applications such as body panels and bumpers etc., the food industry and the hospitality industry and architecture, A2 because of its easy cleaning and corrosion resistance, which are also widely used in engineering, is also preferred by remote control and model making enthusiasts. Also a favorite for many different DIY jobs in and around the house and garage for jobs where a standard BZP closure is not enough.
In general, A2-70 is ideal for a whole range of applications that require a good finish for indoor or outdoor use.
