Small Washer

Small washer is a fastener with an inner bore diameter within the range of 1.6–3.6 mm. The technical requirements for fasteners in this category are regulated by GOST ISO or DIN.

Fasteners with such small parameters are used for joining small components in the assembly and repair of electrical equipment, high-precision instruments and automation systems, in mechanical engineering, and in the medical industry. Small washers are made of stainless steel or carbon steel with electroplated zinc coating.

The small washer ensures joint strength, protects the bearing area of the working surface from deformation, and prevents self-loosening of nuts and bolts. Working with small fasteners requires high precision in fitting all components.
