F436 Washer/Heavy Washer, 1/4" - 4", Zinc plated/HDG
Standard:F436
Description:
F436 washers, also known as heavy washers, are commonly used in structural applications to provide a larger bearing surface and distribute load under the bolt head or nut. They are often used with high-strength bolts.
In terms of surface finishes, two common options for F436 washers are zinc-plated and hot-dip galvanized (HDG).
Zinc-plated F436 washers have a thin layer of zinc coating applied to the surface. This coating provides corrosion resistance and helps protect the washer from rusting. Zinc-plated washers are suitable for applications where moderate corrosion resistance is required. However, they may not provide the same level of protection as HDG coatings in more corrosive environments.
Hot-dip galvanized (HDG) F436 washers undergo a process where they are immersed in molten zinc, resulting in a thicker and more durable coating compared to zinc plating. HDG coatings offer superior corrosion resistance and are well-suited for applications exposed to harsh or corrosive environments.
The choice between zinc-plated and HDG F436 washers depends on the specific requirements of your application, including the level of corrosion resistance needed and the operating conditions the washer will be subjected to. HDG-coated washers generally provide greater corrosion protection and are preferred in more demanding environments.
