Fiberglass Washers
 |
A lightweight alternative to stainless steel, these fiberglass washers have the best strength-to-weight ratio of all our nonmetal washers. Commonly used to distribute pressure under nuts and screws in building frames, they are a great fit when you need something more robust than plastic, but still have to stay within a certain weight limit.
Material Certificate—Washers include a report with a traceable lot number.
