Standard:F436
Description:
The F436 washer is a standard flat washer used in structural applications. However, if you are looking for non-standard washers with the same finishes, such as plain, Dacromet, black oxide, zinc plated, or HDG (hot-dip galvanized), it is possible to find custom-made washers with those finishes.
Non-standard washers typically refer to washers that do not conform to standard sizes or dimensions. These washers are often made to order based on specific requirements. You can contact us to inquire about non-standard washers with your desired finishes.
When communicating with us, provide us with detailed specifications including the dimensions, material, finish, and quantity of the washers you need. We will be able to assist you in creating the non-standard washers with the desired finishes you are looking for.
