Description
Rustic Look, Modern Capability: Contains all the features of a modern day flat washer, but the square design combined with the black oxide finish give it that rustic, old world look
Unique Design: Functions as any regular flat washer but in a decorative square design
Square Flat Washers provide greater bearing surface than standard washers due to increased size and shape. Square washers are designed to prevent bolt heads and nuts from pulling through material. They are most often used in channel applications. Rustic Hardware Square Flat Washers feature a black oxide finish to match the hottest trends in home hardware.
