rondelles cuvette inox, tête fraisée (6 8 10 12) assorties

The cup washers are made of stainless steel, corrosion resistant and durable, and can withstand moisture and other environmental factors without rusting. Decorative washers for countersunk screws have a concave shape, similar to a flat cup or bowl. The inner diameter is designed to fit tightly around the head of the screw or bolt, while the outer diameter provides a larger surface area to distribute the load. The main function is to ensure a smooth and even distribution of the load, which reduces the risk of fasteners damaging the surface material. In addition, this prevents the fixing head from being pulled through the material. Simply place the metal disc on the screw or bolt and insert it into the pre-drilled hole. When tightening the closure, the washers are attached to the surface and thus provide additional grip. Widely used in wood and metal processing as well as general construction to attach fittings such as screws or bolts to surfaces requiring a large bearing surface to prevent damage to surfaces. Can replace damaged washers in machinery, furniture or other objects. Specifications: Material: stainless steel. Colour: silver.
