Steel Spring Washer are often called spring washers in the screw
industry. Its material is stainless steel and carbon steel, carbon
steel is iron. The commonly used spring washers are M3, M4, M5, M6,
M8, M10, M12, M14, M16. These specifications are more commonly
used. Spring washer national standard GB/T 94.1-87, the standard
specifies the standard type spring washer with the specification of
2-48mm.
Carbon steel is the earliest use of modern industry, the largest
amount of basic materials. While endeavoring to increase the output
of low-alloy high-strength steels and alloy steels, various
industrialized countries in the world have also paid great
attention to improving the quality of carbon steels and expanding
their variety and application scope.It is not only widely used in
the construction, bridges, railways, vehicles, ships and various
machinery manufacturing industries, but also in the modern
petrochemical industry, the ocean Development and other aspects
have also been a large number of applications.
Spring washers in the screw industry, often called spring washers.
Its material is stainless steel and carbon steel, carbon steel is
iron. Commonly used spring washers size specifications M3, M4, M5,
M6, M8, M10.M12, M14, M16. These specifications are more commonly
used.

Classify:
1. Internal tooth washer, external tooth washer
There are a lot of sharp, flexible thumbs on the circumference that
press against the bearing surface to stop the fastener from
loosening. Internal rubber washers are used under the heads of
smaller head size; external rubber washers are mostly used under
the head of bolts and nuts. The toothed elastic washer is smaller
in size than ordinary spring washers and has even force on the
fastener to prevent loosening and reliable, but should not be used
in the usual disassembly place.
2. Wave spring washer
Wave washers divided into WG type, WL type, WN type
3. Disc spring washer
Disc spring washer Belleville spring washer, also known as
Belleville French. HDS Series is a very effective bearing load and
elastic recovery. Bolt tension can withstand slack due to wear,
creep, relaxation, thermal expansion, shrinkage, or seal
compression of the consumable parts. The HDS series multiples the
elasticity of the screw several times, effectively replacing
conventional spring washers, but not suitable for locking washers
and flat washers.
