Brass
 |
Softer than most metals, brass washers won't damage other fastening components.
Brass—With a warm, polished look, these washers are often chosen for their appearance. Similar to 18-8 stainless steel, brass is corrosion resistant enough to stand up to wet environments.
Material Certificate—Washers include a report with a traceable lot number.
