- Made In USA for excellent quality conformance
Fiberglass washers are insulators of both thermal and electrical energy. They are chemically resistant, and have a high strength to weight ratio. This series is available from stock in sizes from numbe 2 thru 1" bolt sizes. Larger sizes have an oversized outside diameter, which protects and insulates.
Polyster Glass Laminates (Fiberglass) come in light tan and green colors, this material meets General Purpose NEMA (National Electrical Manufacturers Association) GPO-1 Standards.Temperatures up to aprox 200 degress are not a problem for this material
Made in the USA. These flat washers are produced in the USA for excellent quality conformance. One of the significant differences between less expensive imported products and ours are the way we stamp. Many cheap imports are produced on gang dies that produce 10 or more washers per stroke of the press. Using such a large die means that the individual washer sets are not adjustable - when the punch wears, the dimensions change and there is no way to fix this as the press produces washers, leading to a large variation in the finished part.
Materials available in many other countries are not as consistent as the domestic steels we use, which gives the imports a cheaper cost, but can lead to failures and inconsistencies when the products are used. The Defense Federal Acquisition Regulation Supplement (DFARS) was created to address this problem. Our materials are DFARS compliant although we do not supply the certification except on special order.
