What material is F436?
hardened steel washers
ASTM F436 type 1 is a standard material and dimensional specification for hardened steel washers, intended for general-purpose mechanical and structural use with bolts, nuts, studs, and other internally and externally threaded fasteners.
Are F436 washers hardened?
The chemical, mechanical, and dimensional requirements for hardened washers are covered under the ASTM specification F436. These washers are through hardened or carburized to add strength, but are physically smaller than a standard F844 flat washer.
What is ASTM F436?
ASTM F436 type 1 is a standard material and dimensional specification for hardened steel washers, intended for general-purpose mechanical and structural use with bolts, nuts, studs, and other internally and externally threaded fasteners.
How do I size a washer for bolts?
Most manufacturers usually specify size and OD in fractional inches, although some occasionally use decimal measurements. Example: If you’re determining the diameter of a washer (without knowing the package specs) and measure 5/16 of an inch, it most likely fits a bolt with a diameter of one-quarter of an inch.

What are washers made out of?
Washers are made from a variety of materials, the most popular of which are galvanized carbon steel and stainless steel. Carbon steel is stronger than stainless steel, but stainless steel will not rust or corrode like carbon steel can. Other metal washers include zinc, copper, brass and iron.
Is F436 a Grade 8?
Hardened washers go through a heat treatment process with the intent to make the metal harder.
What is the difference between SAE and USS washers?
USS are coarse threads, while SAE are fine threads. Check your state and local codes before starting any project. Follow all safety precautions. Every effort has been made to ensure the accuracy and safety of this information.
How do you know what size washer to buy?
How to Calculate the Cubic Feet of a Washer
- Measure the depth inside the washer with a measuring tape.
- Measure the diameter of the tub.
- Divide the diameter by two, and square it.
- Multiply the number calculated in Step 3 by the depth of the tub.
- Multiply the number calculated in Step 4 by pi to determine the capacity.
How do you size a washer?
Washer size refers to the diameter of the hardware’s hole and correlates with the bolt diameter. The outside diameter (OD) of a washer is always wider than the fastener. Most manufacturers usually specify size and OD in fractional inches, although some occasionally use decimal measurements.
What is a plain washer?
Plain washers, also known as flat washers, are the most common type of washer. Plain washers do not have a locking function, rather they are used to protect the mating surface from damage.
How are washers sized?
What sizes do washers come in?
Compact washers are normally 2.30 to 2.45 cubic feet, while standard and high efficiency top-load washers may range from 3.1 to 4 cubic feet. If you need one with a larger capacity, check the front loaders. They can range from 4.2 to 4.5 cubic feet. Sometimes, they can go as big as 5 cubic feet.
What is ASTM A307?
