Bronze Washer

A bronze washer is a fastener component that reinforces the bearing area under the head of a bolt, wood screw, or nut.

Tightening a fastened joint with a washer can be done with greater force, while the surface of the joined parts is protected from damage. A bronze washer helps prevent self-loosening of the fastener.

Bronze washers are used in the following cases:

• when it is necessary to reduce wear on moving parts;
• in environments with high humidity;
• in chemical and food production, as well as in the hydropower industry.

Bronze washers are divided into two types: standard ones with a flat working surface, and lock washers. Lock washers are distinguished by notches, teeth, tabs, or projections. The shape can be wave, dished, spring, convex, or in the form of a retaining ring — a washer of any configuration other than flat can be considered a lock washer. The material is bronze of various grades, for example BrO5Ts5S5, BrAZhMts10-3-1.5, or BrA10ZhZMts2.
