Washer flexible corrugated DIN 137B M4 / 4.3 stainless steel A2

Product detailed description

The spring washer, corrugated according to DIN 137B, with a size of M4 and an internal diameter of 4.3 mm, is made of stainless steel class A2, specifically 1.4310. This type of washer is also known under the designation according to the Czech standard ČSN 021733. Spring corrugated washers are structurally designed to provide elastic resistance in joints, thereby increasing stability and preventing loosening of bolted joints due to vibration or dynamic loading.

The A2 stainless steel from which the washer is made is known for its resistance to corrosion, which makes it suitable for use in environments with higher humidity or outdoors. The material 1.4310 is an austenitic chromium-nickel steel that provides good flexibility and mechanical properties, making it ideal for applications where flexibility and wear resistance are required.

The washer has a wavy disc shape, which allows for even pressure distribution on the connecting elements and increases friction between the connecting parts. This design is particularly effective in applications where thermal expansion or contraction of materials needs to be compensated, thus minimizing the risk of the joint loosening.

The use of this flexible washer is suitable in various industrial sectors, including mechanical engineering, automotive and construction, where it is necessary to ensure the reliability and long-term functionality of the joints. Due to its properties, it is ideal for applications where the joints are exposed to dynamic forces or vibrations.
