Washer for rivets DIN 9021 M6 / 6.4 stainless steel A4

Product detailed description

The DIN 9021 rivet washer is designed for applications requiring an extended contact area, which increases stability and load distribution when used with rivets. This particular washer has an inner diameter of 6.4 mm, which is suitable for use with M6 rivets. The outer diameter is approximately three times the hole diameter, namely 18 mm, which complies with ISO 7093 and ČSN 021726 standards for large flat washers. The thickness of the washer is 1.6 mm, which provides sufficient strength and resistance to deformation under load.

The washer material is A4 grade stainless steel, which is known for its excellent corrosion resistance, making it suitable for use in harsh environments, including outdoor applications and environments with high humidity or exposure to chemicals. Class A4 is often used in the marine industry and in applications where high acid resistance is required.

The washer falls into product class C, which indicates a standard processing quality suitable for common industrial applications. It is part of the fastener group, specifically the washer category, and is compatible with DIN 9021, ISO 7093 and ČSN 021726, which guarantees its versatility and wide range of applications within international standards.
