A GI flat washer heavy duty is a galvanized iron washer used with bolts, nuts, anchor bolts, construction bolts, and other threaded fasteners. Compared with ordinary washers, a heavy duty washer is commonly selected when wider support, stronger load distribution, or a thicker washer profile may be needed for fastening applications.

Because washer requirements vary by bolt size and project use, customers should confirm the required inner diameter, outer diameter, thickness, material, finish, and bolt compatibility before purchasing.
