Washer for wooden structures DIN 440R M6 / 6.6 stainless steel A4

Product detailed description

Stainless steel washer for wooden structures according to DIN 440R, ISO 7094 and ČSN 021727 is designed for use in connection applications where it is necessary to ensure uniform pressure distribution under the head of the screw or nut. This washer is made of A4 grade stainless steel, which is known for its high resistance to corrosion, which makes it suitable for use in outdoor and humid environments.

The washer has an inner diameter d1 of 6.6 mm and an outer diameter d2 of 22 mm, which corresponds to the standard size for use with M6 screws. The thickness of the washer is 2 mm, which provides sufficient strength and stability in the connection. The product belongs to the strength class 100 HV, which indicates a material hardness in the range of 100 on the Vickers scale, ensuring resistance to deformation when pressure is applied.

This washer is part of the product class C, which includes flat washers with an extra large diameter, intended for use in wooden structures where the risk of the washer being pressed into softer material needs to be minimized. Due to its dimensions and material properties, it is ideal for applications where long-term reliability and durability of the joints need to be ensured.
