F436M Washer/Heavy Washer, M12-M100, Plain/Dacromet
Standard:F436M
Description:
The F436M washer, also known as a heavy washer, is a metric-sized washer commonly used in structural applications alongside high-strength bolts. These washers help distribute the load and provide a larger bearing surface under the bolt head or nut.
The M12-M100 size range indicates that F436M washers are available in various metric diameters, ranging from M12 to M100.
In terms of surface finish options, F436M washers can be available with a plain finish or a Dacromet finish.
Plain finish refers to washers without any additional surface treatment. They are made of plain steel and do not have any specific coating or finish applied to them. Plain F436M washers are suitable for applications where corrosion resistance is not a primary concern or where additional measures are taken to protect against corrosion.
Dacromet is a high-performance coating that provides excellent corrosion resistance. It is a thin, organic coating applied through a dip-spin process. Dacromet coatings offer superior protection against rust and corrosion, even in harsh environments or exposure to chemicals. This makes them suitable for applications where long-term corrosion resistance is required.
The choice between plain and Dacromet finishes depends on the specific requirements of the application, including the level of corrosion resistance needed and the operating conditions the washer will be subjected to. Dacromet-coated F436M washers offer enhanced protection against corrosion and are often preferred in applications where durability and resistance to rust are critical factors. However, if corrosion resistance is not a major concern, plain F436M washers may be suitable for your application.
